7 x (9 - 5) divided by 2 use pemdas and write 3 steps

ok if 7 is multiplied by (9-5) divided by two I got you

Step-by-step explanation: First you subtract 9 from 5 since it is in parentheses. You got 4 now so your equation is 7 x 4 divided by ( / ) 2 so m comes before d so you multiply 7x4= 28

Now your equation is 28/2 so you get 14.

Step-by-step explanation:

= ( 7 × ( 9 - 5 ) )÷ 2

= ( 7 × 4) ÷ 2

= 28 ÷2

= 14

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
