The two cars drove a combined total of 900 miles, and the sum of their fuel efficiencies was 35 miles per gallon. What were the fuel efficiencies of each of the cars that week? Please help

i think is 3 and 6. this took me 10 min to think.hope to and hope that my answer is brainliest.(follow me )

2 equivalent expressions to represent the area of a rectangle and the top is n-3 and the side is 2

area of the rectangle = length * width

given length = n - 3

width = 2

replace it in the area

so area of the rectangle = (n-3) *2

= 2(n-3)

one of the expression is 2(n-3)

to get another expression we distribute 2 inside the parenthesis

2(n-3) is 2n - 6

so another expression is 2n - 6

two equivalent expression are

2(n - 3)   , 2n - 6
