Answer:
Step-by-step explanation:
Each triangle has a formula of 1/2 a*b
So one triangle = 1/2 * 12 * 15 = 90
So the other one is the same area of 90 square feet.
Together they make 180 square feet.
You can check this by simply multiplying a*b = 12 * 15 = 180 square feet.
4(7a+6)
Factor 28a+24
28a+24
=4(7a+6)
15/56
3*5=15 * 8*7=56

I think the value of o would be 6
