Subtract four times the quantity 2x +5 from three times the quantity 7x-8

13x-44

Step-by-step explanation:

three times the quantity we get 21x-24

four times the quantity we get 8x+20

then we collect like terms 21x-8x and -24-(+20)

21x-8x we get 13x

-24-(20) we get -44(use of direct numbers)

13 x - 44

Step-by-step explanation:

3 (7 x - 8) - 4 (2 x + 5)

21x-24-8x-20

21x-8x-24-20

13x-44

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
