Answer:
(n + 4)(n+ 22)
Step-by-step explanation:
One way to determine which factored expression is accurate is by asking the question: "Which two numbers multiply to 88, but add to 26?" If you are having difficulty using this method, you can always try the guess-and-check method with a multiple choice question. This way involves multiplying the terms inside one set of parentheses with the terms inside the other set of parentheses.
Step #1: Multiply the first terms
(n + 4)(n + 22) ----> n x n = n²
Step #2: Multiply the inside terms
(n + 4)(n + 22) -----> 4 x n = 4n
Step #3: Multiply the outside terms
(n + 4)(n + 22) -----> n x 22 = 22n
Step #4: Multiply the last terms
(n + 4)(n + 22) -----> 4 x 22 = 88
Step #5: Write the new expanded equation and simplify
(n + 4)(n + 22) -----> n² + 4n + 22n + 88 -----> n² + 26n + 88

Answer:
4x=20+4(10); x=15
Step-by-step explanation:
20+4(10)=4x
This is where x is the number of stickers per sheet.
This is the equation because she has 20 stickers.
To find the original number of stickers, we have to add back the amount given.
She has 4 sheets and gave 10 stickers from each sheet. This means she gave away 4*10 stickers.
Now, we can solve the equation:
20+40=4x
60=4x
x=15
