A piece of fabric is 1/3 yard by 3 5/8 yards. Irma solves 1/3 .3 5/8 to find the area of the fabric in square yards.
Enter numbers to complete Irma's calculation for the area.

1/3 x 3 5/8 = (1/3 x 3) + (1/3 x 5/8)

= 3/3 + 5/24

= 29/24

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.

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
