A cell phone company charges $40 per month plus a one time $35 activation fee. Write an expression for the total cost for m months.
40m + 35
Simplify the expression
-7x^2-6x+10x^2-3-2x
3x^2-8x-3
Expand and simplify
-4(1 + 6f) - 10
After being expanded, it would be:
-4 - 24f - 10
So the final solution is:
-24f - 14

7(2 + 6p - 5)
Translate the sentence to a numerical expression:
Add q and p, then subtract 5 from the result
(q + p) - 5
A rectangle has side lengths of 18x - 3 and 12y + x
What is the total perimeter?
There would be 2 of each side length, so the perimeter would be:
38x + 24y - 6
Write the perimeter of the rectangle as an algebraic expression
18x + 10
Expand and simplify
-2(5y + 7) - 11y + 12
After expansion:
-10y - 14 - 11y + 12
After simplifying:
-21y - 2

Lunch in the cafeteria costs y dollars. Grayson buys lunch each day in the cafeteria using a $5 off coupon. Write an expression to represent his total cost if he purchases lunch using a coupon for 5 days in a row.
Cost of lunch after coupon:
y - 5
Cost of discounted lunch for 5 days
5(y - 5)
Write the perimeter of the rectangle as an algebraic expression
12x - 10
Expand and simplify
4 ( 3x + 4 ) - 5 ( x - 7 )
When expanded:
12x + 16 - 5x + 35
The final solution is:
7x + 51
Factor the expression completely
-14g - 21p + 49
-7 (2g + 3p - 7)

Raise x to the 5th power, triple the result, then add n to what you have
3x5 + n
or
3(x5) + n
A triangle has a side length of 12n. The other 2 sides are each twice the size of the first side. What is the total perimeter?
The side lengths would be 12n, 24n, and 24n so the perimeter would be:
60n
Jenna’s age is represented by the expression 5c+3. Her brother Nick is 4 years younger than her. Their youngest brother, Tim, is x years younger than Jenna and Nick's combined age.
Write an algebraic expression to represent Tim's age.
Jenna = 5c + 3
Nick = (5c + 3) - 4 or 5c - 1
Jenna and Nick combined would be 10c + 2
So, Tim would be 10c + 2 - x
Expand and simplify
-6( 3x + 2) - 8( x - 10)
When expanded:
-18x - 12 - 8x + 80
The final solution is:
