1 and -2
Step-by-step explanation:
-2x^2=2x-4 so 2x^2 + 2x -4 = 0
2(x^2+x-2)=0
x^2+x-2 = (x-1)(x+2)
x=1 x=-2

Answer:
5.14
Step-by-step explanation:
36x^2-49
this closely matches the binomial formula of (a+b)*(a-b)=a^2-b^2
so we know:
a^2=36x^2
a=6x
b^2=49
b=7
so (a+b)*(a-b)=(6x+7)*(6x-7)=36x^2-49
1 yd = 3 ft
area= pi r ^2
area=3.14 • 3^2
area= 3.14 • 9
area= 28.26ft^2
rounded to nearest 10th: 28.3 ft^2
ANSWER: J. 28.3 ft 2
