Oneta writes an algebraic expression with three terms. The y-term has a coefficient of -3, and the x-term has a coefficient of 1. The expression does not have a constant term. Which expression could she have written?
x minus y squared minus 3 y
x minus 3 y + 6
x + 3 y squared + 3 y
x + 3 y + 7

Step-by-step explanation:

If X + 3y + 7 is squared by 3y then your answer should be X + 3y sq. + 7 = 10x sq.

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
