80* 4/5
Cross out 80 and 5
You can divide by 5 for both of the numbers
80/5=16
5/5=1
16*4= 64
Answer is 64
Answer:
D) (x - 2)(x² - 8)
Step-by-step explanation:
Separate the polynomial into two groups of two terms and factor out the common value from each group. If the values factored out from each group are the same, then you can use the grouping method. The factors will be the outside terms and the common factor.
x³ - 2x² + -8x + 16
= x²(x - 2) + -8(x - 2)
= (x² - 8)(x - 2)
Answer:
See attached.
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
y = (2x - 2) / 4 Interchange x and y
x = (2y - 2) / 4 Multiply both sides by 4
4x = 2y - 2 Add 2 to both sides.
4x + 2 = 2y Divide both sides by 2
4x/2 + 2/2 = 2y / 2
2x + 1 = y
Now put 3 in wherever you see an x
2*3 + 1 = y
6 + 1 = y
7 = y
