Answer:
40
Step-by-step explanation:
PEMDAS
Do what is in the parentheses first.
-8 * -9 = 72
-9 - 8 + (72) - 15
-9 - 8 - 15 = -32
-32 + 72 = 40
The answer is 42
explanation: if you break the triangle into two triangles, the smaller triangle’s formula would be 1/2 x 6 x 2 which is 12. for the larger triangle the formula would be 1/2 x 12 x 5 which is 30. then you add the areas together. 30+12=42
hope this helped;)
