prove me wrong

Answer:

My answer is 1170 but the way I figured out the problem was by listing numbers 1-30. the problem state that the 1st row had 10, 2nd row had 12, and 3rd row had 14 and so forth. So I basically did the same method till I got to 30 and then add up all the numbers which gave me the answer of 1170.

Step-by-step explanation:

Answer:

1170

Step-by-step explanation:

hey there,

(the other person just calculated each number themselves then added them up which i guess is okay but not in the long term for when you're taking a test for example or your teacher asks you this kind of question so it's better to memorize a formula.)

< There are two types of sequences: arithmetic and geometric. So also two formulas for finding sums of each. This situation is an arithmetic sequence.

Formula for the sum of an arithmetic sequence: [tex]S_n=\frac{n}{2} (a_1+a_n)[/tex]

We know there are 30 total rows so n = 30. a1 is the very first term of a sequence so this is 10 in this situation. Before we fill in the formula, we should find what an is equal to.

For this, we will use the basic formula you learned previously: [tex]a_n=dn+c[/tex]

d (the common difference) = a2-a1 = 12-10=2

c (the common ratio) = a1-d = 10-2 = 8

an = dn + c = 2(30) + 8 = 68

Now that we have found what a_n is equal to, we can plug everything into the sum equation.

[tex]S_n = \frac{30}{2} (10+68)=1170[/tex]

So 1170 is your final answer. >

Hope this helped! Feel free to ask anything else.

Answer:

Option C

Step-by-step explanation:

Given polynomial is,

x² - 3x - 18 = x² - 6x + 3x - 18

                 = x(x - 6) + 3(x - 6)

                 = (x + 3)(x - 6)

We can rewrite the polynomial in factored form as,

x² - 3x - 18 = (x - 6)(x + 3)

Therefore, (x - 6) will be one of the factors of the given polynomial.

Option (C) is the answer.

Answer:

The answer is -5 + 1/8

Step-by-step explanation:

If you use the distributive property, which is mandatory with parenthesis you first multiply -1/2 by 10 which is -5. The next step is to multiply -1/2 by 1/4 which is -0.125 or -1/8, which the closest answer to it is -5 + 1/8. Hope this helps :)

Answer:

x+y=9....(i)

2x-6=y....(ii)

then putting the value of y in (i) eqn

x+2x-6=9

3x=15

x=5

Now, putting the value of x in (ii) eqn

then 2*5- 6 =4

Step-by-step explanation:

SO the value of x is 5 and y is 4

Step-by-step explanation:

Answer:

x = 14

Step-by-step explanation:

Hey there! When it comes to the problem here, both of the degrees should be equal to each other. Setting it up, 4x+1=57 would be how it would be written out, and then you would subtract the 1 to get the 4x by itself. From there, you'd divide 56 by 4, getting you 14. I hope this helped! <3

Answer:

15 nickles 12 quarters

Step-by-step explanation:

Answer:

Suppose: M, N, P, Q are the midpoints of AB, BC, CD, AD respectively

=> MNPQ is the quadrilateral inside ABCD

connect B to D, ΔABD has : M is the midpoint of AB

                                              Q is the midpoint of AD

=> MQ is the midpoint polygon of ΔABD

=> MQ // BD and MQ = 1/2.BD (1)

ΔBCD has: N is the midpoint of BC

                  P is the midpoint of DC

=> NP is the midpoint polygon of ΔBCD

=> NP // BD and NP = 1/2.BD    (2)

from (1) and (2) => MQ // NP ( //BD)

                            MQ = NP  (=1/2.BD)

=> MNPQ is a parallelogram.​

=>  the quadrilateral inside ABCD is a parallelogram.​

Answer:

2x-13

Step-by-step explanation:

Answer:

x = 5cm.

Step-by-step explanation:

Let the number be x

Given the following data;

Length of rectangle = x + 3

Width of rectangle = 2x + 6

Perimeter of rectangle = 48 cm

The formula for the calculating the perimeter of a rectangle is;

Perimeter = 2(L+W)

Substituting into the equation, we have;

48 = 2(x + 3 + 2x + 6)

48 = 2(3x + 9)

48 = 6x + 18

48 - 18 = 6x

30 = 6x

x = 30/6

x = 5

Answer:

A: product of powers

B: quotient of powers

E: negative exponent

Step-by-step explanation:

Let's evaluate to see which several rules we would be applying in each step

[tex] \frac{((-8)^4)^{-5}}{(-8)^6} [/tex]

[tex] \frac{((-8)^{4*-5}}{(-8)^6} [/tex] (power of a power)

[tex] \frac{(-8)^{-20}}{(-8)^6} [/tex]

[tex] (-8)^{-20 - 6} [/tex] (quotient of powers)

[tex] (-8)^{-26} [/tex]

[tex] \frac{1}{(-8)^{26}} [/tex] (negative exponent)

Thus, the rules of exponents we have applied to far are:

A: product of powers

B: quotient of powers

E: negative exponent

Answer:

product of powers

quotient of powers

negative exponent

Answer:

she started with 50 marbles

Step-by-step explanation:

The total is 100 than you just subtract 20 and 30 becasue that is what is added later on. After you subtract 20 and 30 from 100 you will get 50. Therefore Sara had started out with 50 marbles.

Hope that helps :)

Answer: 50 marbles

Step-by-step explanation: Working backwards we ended with 100 marbles so subtracting the 30 marble we're told she bought at the store and subtracting an additional 20 marbles she received for her birthday leaves her with 50 marbles or mathematically 100-30-20=x where x=50

Answer:

$52

Step-by-step explanation:

To find an original price you must find how much of a percent was left before the discount.

100% - 15% = 85%

You then take this percentage a DIVIDE it by the new price.

$44.20/85% = $52 is the original price of the jeans.

Step-by-step explanation:

When f(x) = g(x),

-0.5x + 2 = 2x - 3.

=> 2.5x = 5, x = 2.

The input value that gives the same output in both charts is 2.

Answer:

m = x+y-z

Step-by-step explanation:

Given the expression.

(a^x a ^y) ÷ a^z = a^m

We are to express m in terms of x, y and z.

Using the multiplicative law of indices, the expression becomes:

a^{x+y} ÷ a^z = a^m

Applying the division rule in indices

a^{x+y} ÷ a^z = a^{x+y-z}

The equation becomes

a^{x+y-z} = a^m

Cancel out the base and equate the powers as shown:

x+y-z = m

Hence the expression of m in terms of x, y and z is m = x+y-z
