Answer:

2y + 3d +14\\2(y+7)+3d

Step-by-step explanation:

We remove the bracket and rearrange the numbers to add them. Only similar variables can be added together.

(2y+9)+(3d+5)\\2y+9+3d+5\\2y + 3d + 9 +5\\2y + 3d + 14\\2(y+7)+3d

Answer:

2y + 3d + 14

Step-by-step explanation:

(2y+9) + (3d+5)

First, let us clear the bracket. In doing so, we obtained the following:

2y + 9 + 3d + 5

2y + 3d + 14

What’s the length of three pipes, when combined they equal 72m, how do I find the answer
allochka39001 [22]

Answer:

Each pipe is 24m

Step-by-step explanation:

<u>Given:</u>

  • three pipes
  • combined equal 72m
  • let the variable x represent the length of 1 pipe

<u>Algebraic Expression</u>:

3 pipes times length equals 72m (the total length)

3x = 72, we want x to be alone so divided both sides by 3

3x / 3 = 72 / 3

x = 24

The function f is defined by f(x) = x^2 + 3x -10 , if f(x + 5) = x^2 + kx + 30, k=
boyakko [2]

Answer:

k = 13

Step-by-step explanation:

substitute x = x + 5 into f(x) , that is

f(x + 5) = (x + 5)² + 3(x + 5) - 10 ← expand squared factor using FOIL

          = x² + 10x + 25 + 3x + 15 - 10

         = x² + 13x + 30

compare this with f(x + 5) = x² + kx + 30

for the 2 expressions to be equal , then k = 13
