Answer:
C. 850,668
Step-by-step explanation:
Since order doesn't matter, we use the combination equation: nCr
We first need to find n, which would be 42. Then we find r, which is 5.
We plug them into either the equation or a calculator
(42!)/(5!(42-5)!) = 850,668
Answer:
(z+6)(z+6): z ^ 2 + 12z + 36
(x+5)(x+5): x ^ 2 + 10x + 25
Step-by-step explanation:
For the trinomial to be a perfect square trinomial the coefficient for the x^2 term must. E a perfect square.
Letter C
9=3^2
3^(2x)=(3^2)^(3x-4)
3^(2x)=3^(6x-8)
2x=6x-8
0=4x-8
8=4x
2=x
