Answer:
-2(x^2 - x - 1).
Step-by-step explanation:
3x - 2x^2 - x + 2
= 2x - 2x^2 + 2
= -2(x^2 - x - 1)
Answer: 180= 38+(17x+1)+(3x+1), All the angles in a triangle add up to 180 degrees, so I made all the add measures equal to 180 degrees.
Just solve that equation to find x. Then used then plug in the x value to (17x+1). After you solve that put it equal to 2y to solve for y.
So the y equation would look like: 2y=(17x+1) (but you would have solved for x and then plugged it in to the equation)

Answer: 12.5 in. high
Step-by-step explanation: to get from 4 to 10, you have to muliplty by 2.5.
if you multiply 5 by 2.5, the answer is 12.5
<span>6x-7y=-84
7y = 6x + 84
y = 6/7(x) + 12</span>
