Answer: 
Step-by-step explanation:
First, we divide the composite figure into two distinct geometric shapes. This would be a triangle and a square. To find the triangle we use the formula:
A = 1/2bh
To find the base of the triangle we can add:
9 + 9 + 18 = 36
Now we plug in and solve:
A = 1/2bh
A = 1/2(36)(27)
= 1/2(972)
= 486
To find the square, we can use length x width:
18×18 = 324
Now, we add the sums together:
486 + 324 = 810
7 is in the ones place value.
9 is in the tens place value.
Hope this helps.

First, you multiply all terms by 2.8 to get rid of the denominator:
m-13.72 = -19.908
then, you isolate the m on one side of the equation and all other terms on the other side:
m = -19.908+13.72
m = -6.188

Answer:
X= -13
Step-by-step explanation:
The goal is to get x by itself!
<em>Rule of thumb: whatever you do to the left, you MUST do to the right</em>
Step 1: Subtract 8 from the left side of the equation (the = sign)
x + 8 = (-5)
- 8 --> this gets x by itself
Step 2: Subtract 8 from (-5) on the right side <em>(because you did it on the left</em>
x = (-5)
- 8
*<em>note: x is now by itself*</em>
Step 3: Solve!
x = (-5) - 8 -13
x = -13
