Answer/Step-by-step explanation:
Parallelogram A:
Area = 5x + 20
Base = x + 4
Height = h = ?
Area of Parallelogram = base * height
Plug in the values
5x + 20 = (x + 4) * h
Divide both sides by x + 4
[tex] \frac{5x + 20}{x + 4} = h [/tex]
[tex] \frac{5(x + 4)}{x + 4} = h [/tex]
[tex] 5 = h [/tex]
Height = 5
Parallelogram B:
Area = 8x - 24
Base = b
Height = 8
Area of Parallelogram = base * height
Plug in the values
8x - 24 = b * 8
Divide both sides by 8
[tex] \frac{8x + 24}{8} = b [/tex]
[tex] \frac{8(x + 3)}{8} = b [/tex]
[tex] x + 3 = b [/tex]
Base = x + 3
Parallelogram C:
Area = 12x + 6y
Base = 6
Height = h = ?
Area of Parallelogram = base * height
Plug in the values
12x + 6y = 6 * h
Divide both sides by 6
[tex] \frac{12x + 6y}{6} = h [/tex]
[tex] \frac{6(2x + y)}{6} = h [/tex]
[tex] 2x + y = h [/tex]
Height = 2x + y

x+2y=13
3x-5y=6
what is (x,y)?
Answer:
x+2y=13
Step 1: Add -2y to both sides.
x+2y+−2y=13+−2y
x=−2y+13
Answer:
x=−2y+13
Step 1: Add 5y to both sides.
3x−5y+5y=6+5y
3x=5y+6
Step 2: Divide both sides by 3.

Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define Systems
x + 2y = 13
3x - 5y = 6
Step 2: Rewrite Systems
x + 2y = 13
Subtract 2y on both sides: x = 13 - 2yStep 3: Redefine Systems
x = 13 - 2y
3x - 5y = 6
Step 4: Solve for y

Equality PropertiesStep-by-step explanation:
Step 1: Define
2/5(x - 2) = 4x
Step 2: Solve for x
Distribute 2/5: 2/5x - 4/5 = 4xSubtract 2/5x on both sides: -4/5 = 18/5xDivide both sides by 18/5: -2/9 = xRewrite: x = -2/9Answer:
x = -2/9
Step-by-step explanation:
Multiply both sides by 5
2(x - 2) = 4x*5
2x - 4 = 20x Subtract 2x from both sides
-4 = 18x Divide by 18
-4/18 = x
x = -2/9

What’s the value of 2/3 * 1/8
Answer:
The simplified value is 1/12.
Step-by-step explanation:
Since we need to multiply these fractions, we can just multiply the numerators and denominators together in order to find the answer.
2/3 x 1/8 =
2/24 =
1/12
Therefore, the simplified value is 1/12.

Answer:
x = 6
Step-by-step explanation:
The angle bisector divides the triangle proportionally. Here, the top segment on each half is double the length of the bottom one, (8 = 2·4), so ...
x = 2·3
x = 6
_____
If you like, you can write that as a proportion:
x/3 = 8/4
x = 3(8/4) = 3·2 . . . . . multiply by 3 to get x by itself
x = 6

That is my question
Answer:
I need one more brainliest!!!
Step-by-step explanation:
6.14-(9+8)2
6.14-17(2)
6.14-34=
-27.86
Hope this helped!
The required simplified value of the 6.14-(9+8)2 is -27.86.
Given that,
An expression is given, 6.14-(9+8)2
A simplified value is to be determined.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
What is arithmetic?In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
Here,
= 6.14-(9+8)2
Using the PEMDAS rule,
Using distributive property in order to solve the parenthesis first.
= 6.14 - 17 * 2
Following PEMDAS solve 17 * 2 first.
= 6.14 - 34
Now, subtraction
= -27.86
Thus, the required simplified value of the 6.14-(9+8)2 is -27.86.

I need to find the answer to S
Answer:
65º
Step-by-step explanation:
(the sum of the angles of a triangle) 180- 65= 115
65= 30+ 35
180- 115=65
Answer:
I'm pretty sure the answer is 65
Step-by-step explanation:
30+35=65
180-65=115
So the 3rd angle in the triangle is 115°
Then you subtract 115 from 180 and get 65°
So S equals 65°

i need help with a function
Answer:
one: 9
Two: D
Step-by-step explanation:
One
The symbol used is x≥8 so 8 is included in the function part. That would mean that F(x) = 9
Two
The value you need to use is -4x + 3. That's because -2≤x and the symbol ≤ makes - 2 inclusive.
-4(-2) + 3 = 8 + 3 = 11
3a
The function is decreasing over -4x + 3
It goes from 11 to -29 roughly. That means it's going from a positive to negative number. Definitely decreasing
3b
The function is a constant when x≥8. The value of the function is 9 no matter what x is.
3c
The function is increasing from - 2x to 8 which is going from -9 to 11
