Answer:
{-6}
Step-by-step explanation:
Step 1 Raise both sides of the equation to the index of the radical in the case 2
Step 2 Factor
(x + 6)(x + 6) = 0
x + 6 = 0
x = - 6
Step 3 Check -6
We need to distribute the term 4x to x - 6. Basically, we need to multiply 4x by x, which gives us 4x², and 4x by -6, which gives us -24x. Putting our two derived terms together, we get 4x²- 24, which is your answer. Hope this helps and have a great day!
Area=legnth times width=31
the frame must go around the frame with equal legnth, x
so
the total area (meaning the frame +picture) is 5+x by 6+x
31=(5+x)(6+x)
expand
31=30+11x+x^2
minus 31 both sides
0=-1+11x+x^2
x^2+11x-1=0
answer is third one
Slope -- -4/3
y intercept --- -7
hope this helps!
