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
I would say the answer is b, because it is a rhombus gape and all sides are congruent and there are 4 sides
51=?
60 100
Then you cross-multiply the 51 and the 100 and get 5,100.
Next you take the 5,100 and divide it by the 60 which gives you your final answer of 85%.
Answer: the answer would be 66

Answer:
6x2+8x−8
Step-by-step explanation:
6x3+26x2+16x−24
x+3
=
6x3+26x2+16x−24
x+3
=
2(x+2)(x+3)(3x−2)
x+3
=
6x2+8x−8
