<h3>
Answer: x*a^2 or a^2*x</h3>
======================================
Work Shown:
a^(b+2) = a^b*a^2 ... break up the exponent
a^(b+2) = x*a^2 ... replace a^b with x
We don't know the value of 'a' nor the value of x, so we cannot evaluate further. This is the same as a^2*x because order of multiplication does not matter. For example, 2*3 = 6 and 3*2 = 6, so 2*3 = 3*2.
We simply replace a with -9
k(-9) = 4 * -9 - 4
k(-9) = -40

You would use HL to prove they are congruent! To prove of they were triangles you wouldn't use any of those I don't think.
Answer:
56
Step-by-step explanation:
If there are 70 total magazines, and 80% are womens, then you just multiply 70 * .80 = .56
