99 plus 9 tens?? if so, 189
I would say that y=x2+4x+8 simply because it matches what the original equation
Answer: A. 9x^2+2x-5
Step-by-step explanation: its just adding the two numbers from right to left so +3-8= -5 then -5x+7x=2x then 6x^2+3x^2= 9x^2 so putting them together equals 9x^2+2x-5
(9x+1)=(7x+13)
2x+1=13
2x=12
x=6
7(6)+13
42+13
55
180-55
125
y= 125°
