Answer:
x²
Step-by-step explanation:
Given: 2x(2x - 3) - 3x(x - 2)
Distributive Property: a(b + c) = ab + ac
1. Distribute
⇒ 2x(2x) + 2x(-3) + -3x(x) + -3x(-2)
⇒ 4x² - 6x - 3x² + 6x
2. Combine like terms
⇒ 4x² - 3x² - 6x + 6x
⇒ x²

Answer:
Step-by-step explanation:
we know that
The inscribed angle is half that of the arc it comprises.
so
In this problem
Let
x-----> the measure of an arc intercepted by an inscribed angle
We have to find the slope of these lines using the slope formula
<span>slope = (y2 - y1) / (x2 - x1) </span>
<span>Line WX : </span>
<span>(-1,2) x1 = -1 and y1 = 2 </span>
<span>(4,12) x2 = 4 and y2 = 12 </span>
<span>now sub into the slope formula </span>
<span>slope = (12 - 2) / (4 - (-1) </span>
<span>slope = 10/(4 + 1) </span>
<span>slope = 10/5 which reduces to 1/2 </span>
<span>so the slope of line WX = 1/2 </span>
<span>Line YZ : </span>
<span>(5,8) x1 = 5 and y1 = 8 </span>
<span>(-2,-6) x2 = -2 and y2 = -6 </span>
<span>now we sub into slope formula </span>
<span>slope = (-6-8) / (-2-5) </span>
<span>slope = -14/-7 </span>
<span>slope = 1/2 </span>
<span>so the slope in line YZ = 1/2 </span>
<span>Line WX and line YZ are : (D) parallel because the slopes are the same.</span>
If x is under a square root (
) then x cannot equal a negative number. If x is in the denominator of a fraction (
) then x cannot equal zero.
