Answer:
a = 5
Step-by-step explanation:
According to the factor theorem, if x + 2 is a factor, then by dividing the polynomial by the binomial, we are meant not to have a remainder
In this case, the remainder would be zero
So, if we set the binomial equals zero and substitute the x-value into the polynomial, we are supposed to have 0
So we have this as;
x + 2 = 0
x = -2
-2^3 -2(-2)^2 -2(a) + 6 = 0
-8-8-2a + 6 = 0
-16 + 2a + 6 = 0
2a -10 = 0
2a = 10
a = 10/2
a = 5
X+2 < 7
Subtract both sides by 2
x < 5
Any value where x was less than 5 would be correct.

Answer:
she will have read 15 books in all
Step-by-step explanation:
if she has read 10 books in 2 months that means she has read 5 books each month, because 10 ÷ 2 = 5.
so if another month passes by that means she reads another 5 books.
10 + 5 = 15
so in total britney has read 15 books in total
