Answer:
I dont really understand it but I think it's the first one cuz that's the only one that makes sense to me hope it helped tho:))))))))
Polynomials are perfect squares when the first term (term x2) and the third term (term 49) are both squares. In order to find the value of b, you must take the square root of the third term and multiply by the exponent in the first term. This means since the sqrt(49) is 7, and 7x2=14; then the correct answer is C. 14.
-- Remember this only works on perfect square polynomials.
18b^2 : 45b
Divide by 3b
6b : 15
Divide by 3
2b : 5
<h3>Answer:</h3>
A. 5/4 . . . or . . . 1.25
B. see below
<h3>Explanation:</h3>
B. The dilation factor is the ratio of the image lengths to the original lengths. Here, for example, that could be
... d = E'F'/EF = (-4-(-9))/(-2-(-6))
... d = 5/4
A. The result of the calculation of part B is 5/4 = 1.25.
