Answer:
B. 24 in
Step-by-step explanation:
Add the known sides = 19 in
To solve for the two unknown sides -
Side across from the vertical 3 in is the same, so add another 3 inches to 19 = 22 in
For the side across from the 7in you need to subtract the horizontal sides next to it that you already know.
7 = 3 + 2 +x
x = 2
so add 2 in
22 + 2 = 24in
The coefficient would be 1
before every variable, there is a one
So, x is equal to 1x
x+x is 2x
hope this helps:)
