Answer:
x = 31
Step-by-step explanation:
For the sum of the saved amounts to be 286, we must have ...
(5x +4) +(4x +3) = 286
9x = 279 . . . . . . . . . . . . . subtract 7
x = 31 . . . . . . . . . . . . divide by 9
The value of x would be 31.
The solution to the answer is as follows:
We have...
y = (x + 9)(x + 6)
Then...
<span>y = (x + 5(9)) (x + 5(6))
</span>
= (x + 45) (x + 30)
<span>Hence, the x-intercepts are -45 and 30.
