Answer:
x = −10 and x = 4
Step-by-step explanation:
x2 + 6x = 40
Subtract 40 from each side
x^2 + 6x -40 =0
Factor, what 2 numbers multiply to -40 and add to 6
10 * -4 = -40 10+-4 = 6
(x+10) (x-4) = 0
Using the zero product property
x+10 =0 x-4=0
x=-10 x=4
4 10/8 breaks down to 5 2/8 = 5 1/4
3 1/2 + 1 3/4
3 1/2 = 3 2/4
3 2/4 + 1 3/4 = 4 5/4
the correct answer is 5 1/4
so yes, your answer IS correct!
