Zx and Zy are supplementary angles. Zy measures<br> 156°<br> What is the measure of Zx?

cupoosta [38]

Answer:

Zx = 24 degrees

Step-by-step explanation:

since it is supplementary it adds up to 180 degrees. so you have part of the angle (156 degrees) so the equation would be 180 - 156 = Zx (origionally Zx + 156 = 180).

Write g(x) = 4x2 + 88x in vertex form. The function written in vertex form is g(x) = ___ (x +11)2 +____.

wel

$The\ vertex\ form:\\\\f(x)=a(x-h)^2+k$

$\text{Use}\ (a+b)^2=a^2+2ab+b^2\qquad(*)$

$g(x)=4x^2+88x=4(x^2+22x)=4(x^2+2\cdot x\cdot11)\\\\=4(\underbrace{x^2+2\cdot x\cdot11+11^2}_{(*)}-11^2)=4[(x+11)^2-121]=4(x+11)^2+(4)(-121)=4(x+11)^2-484$
