A triangle has an area of 45 square inches, and its base, x, is 6 inches more than its height, yWrite an equation involving x and y to express the fact that "the triangle has an area of 45 square inches." Write an equation involving x and y to express the fact that "its base is 6 inches more than its height." Use substitution to merge the two equations together into one equation involving only one variable. Solve the equation from part Show all work/steps to solve the equation. Identify the height, y, of the triangle:Identify the base, x, of the triangle:

d. is the correct answer

step-by-step explanation:

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
