A. Translate each of the following into algebraic expressions: (1 point each)
1.x plus y squared ---> x + y^2
2.8 times a number, x, decreased by y ---> 8x - y
3.the sum of x and y, squared ---> (x + y)^2
4.3 times the difference of x and y ---> 3( x - y)
5.6 less than x cubed --- > x^3 - 6
B. Translate the following phrases into algebraic expressions. Explain,
in complete sentences, the difference between the two. (3 points)
´twice the sum of x and y ---> 2(x + y)
´the sum of twice x and y ---> 2x + y
The first one adds first x and y, and then doubles the result, while the second one first doubles de value of x and the adds y.
C. Create your own example of a mathematical phrase you might hear in
the real world and provide the translation for it. Be sure to identify
what part of the phrase i
The sales of this year exceeded the sales of last year in tweny millions.
y = x + 20,000,000, where x represents the sales of last year and y represents the sales of this year,

Hope this helps
Good Luck
It’s A. $25.20
You find the rate you dividing the cost ($18) by how many gallons (5). Then you multiply by what you are looking for (7 gallons). You get 25.20.
The answer i choose is $5.50 because i added $3.00 and $2.50. so thats how i got my answer
