To find a perimeter, add all sides together:

9) 12 + 12 + 8 + 8 = 20 + 20 = 40 in
10)  3 + 3 + 3 + 3 = 6 + 6 = 12 cm

To find area, multiply length and width, or base and height:

11) 3 x 6 = 18 
12) 10 x 30 = 300 ft
13) 12 x 12 = 144 cm
14) 7 x 4 = 28 m

15) 
Perimeter: 2(2) + 2(16) = 4 + 32 = 36
Area: 1 x 16 = 16


hope this helps

navik [9.2K]

Answer:

3.3

Step-by-step explanation:

Hour : H

subtract the 75 from both sidesso the variable would be on one side and the knowns would be on the other side

45H + 75 = 225

        -75      -75

Divide by 45 from both sides

45H = 150

÷45     ÷45

Someone please help me with math linear equations 3x + 2y = 12
vodka [1.7K]
3x + 2y = 12
subtract 3x from both sides
2y = -3x + 12
divide all terms by 2 so that you can have only the y on the left side
y = -3/2x + 6
And that is your answer!

Hope this helped!! :)

Geometry math question no Guessing and Please show work thank you

Theorem

In a triangle, the measure of an exterior angle equals the sum of the measures of its two remote interior angles.

x + y = z

4n - 18 + n + 8 = 133 - 6n

5n - 10 = 133 - 6n

11n = 143

n = 13

z = 133 - 6n = 133 - 6(13) = 133 - 78 = 55

Answer: C. 55

WORTH ALL MY POINTS PLEASE HELP

Answer:

  (a)  = 7 +3·5

Step-by-step explanation:

The given expression evaluates to ...

  6 +2^4 = 6 +16 = 22

The offered choices evaluate to ...

  7 +3·5 = 7 +15 = 22

  4·10^3 +96 = 4·1000 +96 = 4096

  7^2 = 49

  3·10 +2 = 30 +2 = 32

The only choice that will form a proper equation is the expression that evaluates to 22:

  6 +2^4 = 7 +3·5
