D

Answer 2

Which of the following shows 8x3y + x2 - 14z - 2 + 5y2x written in standard form?
a. -14z + 8x3y + 5y2x - 2 + x2
b.8x3y + 5y2x + x2 - 14z - 2
c.8x3y + x2 + 5y2x - 14z - 2 x2 - 2
d.- 14z + 5y2x + 8x2y

Answer 3

8x3y + 5y2x + x2 - 14z - 2

Answer 4

B

Answer 5

how?

Answer 6

there are 2 others that are bigger than that..just look for the one's with the bigger exponents(the small numbers on top)

8x^3y is the biggest because it has an exponent of 3.

Answer 7

k!

Answer 9

Mike packed an equal number of flashlights in each of x gift boxes. The number of compartments in each gift box was 3 more than the number of boxes. The number of flashlights in each compartment of a box was 2 more than the number of compartments in each box. The expression below shows the total number of flashlights that Mike packed in all the boxes:

x(x + 3)(x + 5)

Which expression shows the number of compartments in each gift box?
x + 3
x + 5
(x + 3)(x + 5)
x(x + 3)(x + 5)

Answer 10

c

Answer 11

again how?

Answer 12

let's say there were 3 boxes. This would mean x = 3. The number of compartments in each box would be 5, and the number of flashlights in each compartment would be 8.
Multiply 8 by the number of compartments in each box (5) and we get 40. Plug x = 3 into each equation, and see which one comes out to 40
the number of compartments in each box would be 6, which would mean the solution would be 48
