If I pick 10, then 2(10)+13=33
If I pick 15, then 2(15)+13=43
If I pick 12, then 2(12)+13=37
10) 7(2m+3)
11) 3(3r-1)
12) 2p(5q+4)
Answer:
True
Step-by-step explanation:
If you subtract 16 on both sides... x will be alone. Therefore 51-16=35
x=35 (B)
Answer:
<em>The binomial is a factor</em>
Step-by-step explanation:
In order to show that x+3 is a factor of the polynomial, then;
f(a) = 0
Get a by equating x+3 to zero
x+3 = 0
x = -3
Get f(-3)
f(-3) = (-3)^4 + 8(-3)^3 + 11(-3)^2 -11(-3) + 3
f(-3) = 81 - 216 + 99 + 33 + 3
f(-3) = 216-216
f(-3) = 0
<em>Since the remainder of the polynomial when divided by x+3 is zero, this shows that x+3 is a factor of the given polynomial</em>
