X(x - 2) = 4 [upon multiplying and moving the 4 becomes x² - 2x - 4 = 0] x(2x + 3) = 12 [upon multiplying and moving the 12 becomes 2x² - 3x - 12 = 0] 3x(x + 8) = -2 [upon multiplying and moving the -2 becomes 3x² + 24x + 2 = 0]

Triangle abc is a right traingle if side ac=7 and side bc= 10 what is the measure of ab?
Artist 52 [7]
<span>Use the Pythagorean theorem for the right triangle ABC, where

AB is the hypotenuse of the triangle;

AC and BC are the other two sides.


So,

(AC)^{2}+(BC)^{2}=(AB)^{2}\\\\ 7^{2}+10^{2}=(AB)^{2}\\\\ (AB)^{2}=49+100\\\\ (AB)^{2}=149\\\\ AB=\sqrt{149}

A) y=(-0.49)x²+23.38x+996.03
B) 1267.63

Using the equation from part A, substitute 20 in place of x:
y=(-0.49)(20²)+23.38(20)+996.03
y=1267.63
