For f(x)= 2x+1 and g(x)=x²-7, find (f-g)(x)
a. x²-2x-8
b.-x²+2x-6
c.-x²+2x+8
d.2x²-15

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!

6 and 24

step-by-step explanation:

6 x 4 = 24

180°

step-by-step explanation:

sum of equilateral triangle=180°

< n=60°

< m=120°°[angle supplementary of equilateral angle]

< m+< r+< x=360°(sum of exterior angle of triangle)
