Answer:
It simplifies to 2x + 2.
Step-by-step explanation:
Let the number be x, then the expression is
x + 5 + (x - 3)
= x + 5 + x - 3
= x + x + 5 - 3
= 2x + 2.
8 * 5 = 40
40 * 4 = 160
160 * 12 = 1,920
Answer: $1,920

Answer:
Step-by-step explanation:
1 In general, given a{x}^{2}+bx+cax
2
+bx+c, the factored form is:
a(x-\frac{-b+\sqrt{{b}^{2}-4ac}}{2a})(x-\frac{-b-\sqrt{{b}^{2}-4ac}}{2a

2 In this case, a=1a=1, b=-2b=−2 and c=-2c=−2.
