B - 8 = 5
------ ---
b + 9 2
Cross Multiply
2(b-8)=5(b+9)
distribute
2b -16 = 5b + 45
subtract 5b from both sides
-3b - 16 = 45
add 16 to both sides
-3b = 61
divide both sides by -3
b = -61/3 or -20 1/3
Answer:
8 square units
Step-by-step explanation:
First, split this figure into 3 known figures:
2 unit by 2 unit triangle
2 unit by 2 unit square
2 unit by 2 unit triangle
Then solve all these areas:
2 x 2 = 4 / 2 = 2
2 x 2 = 4
2 x 2 = 4 / 2 = 2
Then add all these areas:
2 + 4 + 2 = 8
