Pls show work. 3.14 for pi
stepan [7]
The easiest way to do this is to split each figure into smaller shapes.  
1. a rectangle and a triangle
2. 3 separate rectangles
3. triangle and rectangle
... so on
You then find the areas of the smaller shapes and then add them together.
1. (for rectangle) 6*3 = 18
    (for triangle) (12*15)/2 = 90         90 + 18 = 108
2. 4*8 = 32
    8*4 = 32
    12*12 = 144           32 + 32 + 144 = 208
...so on

Which would not be a step in solving 5x + 15 + 2x = 24 + 4x?
Klio2033 [76]

Answer:

A. Use the distributive property.

Step-by-step explanation:

We cannot use the distribute property because there are not parentheses to distribute a number through.

5x + 15 + 2x = 24 + 4x

We can collect the terms, and isolate the variable

Alenkinab [10]

Answer:

\huge\boxed{\sf t = 0.6}

Step-by-step explanation:

\sf 0.15(10t-9) = 0.75(4t-3)\\\\Resolving \ Parenthesis\\\\1.5t-1.35 = 3t - 2.25\\\\Combining \ like \ terms\\\\-1.35 + 2.25 = 3t-1.5t\\\\0.9 = 1.5t\\\\Dividing \ both \ sides \ by \ 1.5\\\\0.9/1.5 = t\\\\0.6 = t\\\\OR\\\\\bold{t = 0.6}

Hope this helped!
