I will assume that you meant (4/5)x - 9 = 3. In other words, (4/5) is the coefficient of x.

Start by adding 9 to both sides: (4/5)x - 9 + 9 = 3 + 9, or (4/5)x = 12.

To isolate x, mult. both sides by (5/4): (5/4)(4/5)x = (5/4)(12)

Simplifying this result, x = 15

the area formula is a parallelogram is equal to (Base)*(height). If the area if a parallelogram is given by the trinomial x^2-14

abruzzese [7]

Answer:

x-12

Step by step explanation:

Here it is given that the area of a parallelogram is given by base * height. And if the area is represented by ,

$\longrightarrow A = x^2-14x+24$

And the base of the parallelogram is given by,

$\longrightarrow Base = x-2$

Substituting the values in the given formula, we have;

$\longrightarrow Area = base \times height$

$\longrightarrow x^2-14x+24=h(x-2)\\$

Divide both sides by (x-2) .

$\longrightarrow h =\dfrac{x^2-14x+24}{x-2}$

Factorise the term in numerator,

$\longrightarrow h =\dfrac{x^2-12x-2x+24}{x-2}\\$

$\longrightarrow h =\dfrac{x(x-12)-2(x-12)}{x-2}\\$

$\longrightarrow h =\dfrac{(x-2)(x-12)}{x-2}$

Simplify,

$\longrightarrow \underline{\underline{ height= x-12}}$

This is the required answer!

Dan will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of 53.96

Alja [10]

53.96+0.17x =57.96+0.12x
0.17x-0.12x=57.96-53.96
0.05x=4.00
x=80 mi
