to find the area of compound shapes, you break them apart and find each shapes area then add it together.
to find the area of a square, use A=l * w
to find the area of a triangle, use, A= 1/2 b * h
Negative exponents mean that the base is on the wrong side of the fraction line. For example, x^-2 is the same as 1/x^2. In this example, 1/2^-2 would be 2.
2/1^2 = 2
Answer: -12r-12
Step-by-step explanation: There is no equals sign so you can't solve it but you can simplify it. You start out with -3(4r-8)-36. Then, you use PEMDAS. (-3×4r)+(-3×-8)-36. Then, it turns into -12r×+24-36. You just continue to simplify until you can't anymore. You end up with -12r-12.
