Mika used division to rewrite 5/ 40 as 0.125. Explain what she should do next to convert 0.125 to a percent.

Mika changed the fraction to a decimal by dividing. Now she can change the decimal to a percent by moving the decimal two places to the right and adding a percent sign.

r and t.

both are 64 degrees.

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

mrb
