Answer:
the answer is X=-8 or X= 2
Step-by-step explanation:
subtract 10 from both sides in order to eliminate 10.
x^2 + 6x -16
find two factors of -16 that sum up to 6.
-2 and 8 are two factors of -16 that sum up to 6.
(x-2)(x+8)
x-2= 0, x= 2
x+8= 0, x = -8
Answer:
4(n+7)=
Step-by-step explanation:
4 times the sum of the equation n plus seven
So plug in the 5 for x. it would look like 7(5+4). you do PEMDAS and then looks like 7(9) and 7 multiplied by 9 equals 63.
Answer:
80
Step-by-step explanation:
Circle circumference = 2*pi*r
160*pi = 2*pi*r
(160*pi)/2*pi = (2*pi*r)/2*pi
80 = r
