4z - ( - 3 z)
= 4 z + 3 z = 7 z
Answer:
a) GCF = 8
Step-by-step explanation:
b)
Formula of the area of triangle
A=(1/2)a*b*sin(C)
a, b - sides
C- an angle between sides a and b.
Probably, this question means that you need to know sin of the angle.
I agree with you on this problem. It is A. If that is the final answer, the negative exponent must be flipped in order to be positive. According to the equation, it is not positive so it is not a simpflied polynomial.
