Roy has a 120-meter strip to work with.
How many 1 decimeter pieces can be cut from his strip

1,200 one decimeter pieces can be cut

Step-by-step explanation:

Find how many 1 decimeter pieces can be cut by converting the 120 meters to decimeters.

In 1 meter, there are 10 decimeters.

So, convert 120 meters to decimeters by multiplying it by 10:

120(10)

= 1,200

So, there are 1,200 decimeters in the strip. This means that 1,200 one decimeter pieces can be cut, since 1,200 divided by 1 is 1,200.

So, 1,200 one decimeter pieces can be cut

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
