Pani-rosa [81]

D. (y-3)
I'm assuming that they want you to find the factors of the quadratic expression, which are (y-5)(y-3). (y-5) isn't up there, so (y-3) is the only solution that's really possible.

Answer:

Step-by-step explanation:

This triangle is a 3-4-5 Pythagorean Triple. 9 is 3*3, 15 is 5*3, so b is 4*3, which is 12. Alternatively, you could use the Pythagorean Theorem's converse, sqrt(15^2-9^2), and get 12.

Answer:

115°

Step-by-step explanation:

1. Calculate the value of x

$\begin{array}{rcc}m\angle GFM + m\angle NFE & = & m\angle GFE\\4x + 10 + 14x + 3 & = & 157\\18x + 13 & = & 157\\18x & = & 144\\x & = & \dfrac{144}{18}\\ & = & 8\\\end{array}$
