Here is rectangle A. Block A. Rectangle B is ¹/₅ longer than A Block B. Rectangle C is ¹/₃ longer than B Block C. The total length of all three rectangles is 133 cm. How much longer is rectangle C than B?

Rectangle C is 14 cm longer than B

Step-by-step explanation:

Let  x be the length of Rectangle A. Rectangle B is ¹/₅ longer than A Block B,

Therefore the length of rectangle B is:

Rectangle C is ¹/₃ longer than B, therefore the length of rectangle c is:

The total length of all three rectangles is 133 cm.

Length of rectangle A + Length of rectangle B + Length of rectangle C = 133 cm

Therefore the length of rectangle A is 35 cm, the length of rectangle B is and the length of rectangle C is

Rectangle C is ¹/₃ longer than B, which is 14 cm (42\3) longer than B

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

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

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!
