The rectangle below has an area of x^2-7x+10x square meters and a width of x-5x meters. What expression represents the length of
sergey [27]

Answer:

The area of a rectangle is:

\sf A=lw

Plug in what we know:

\sf x^2-7x+10=l(x-5)

Factor the left side:

\sf (x-2)(x-5)=l(x-5)

Divide (x - 5) to both sides:

\sf l=\boxed{\sf x-2}

So the length is x - 2 meters.

Square root of 5u+2 = square root of 3u+14
alina1380 [7]
Sqrt(5u + 2) = sqrt(3u + 14)
Square both sides to clear the square root.
5u + 2 = 3u + 14
subtract 3u from both siides
2u + 2 = 14
subtract 2 from both sides
2u = 12
divide both sides by 2
u = 6
When you square a square root you MUST check the solution.
sqrt(5*6 + 2) = sqrt(3*6 + 14)
sqrt(32) = sqrt(32)

Find the inverse of the following function​
KatRina [158]

f-¹(x)=\frac{2-7x}{x+2}

Answer:

Solution given:

f(x)=\frac{-2x+2}{x+7}

Let f(x)=y

y=\frac{-2x+2}{x+7}

Interchanging role of x and y

x=\frac{-2y+2}{y+7}

doing crisscrossed multiplication

x(y+7)=-2y+2

now solve it:

xy+7x=-2y+2

keep like terms in one side

xy+2y=2-7x

take common

y(x+2)=2-7x

make a value of y

y=\frac{2-7x}{x+2}

So,

f-¹(x)=\frac{2-7x}{x+2}
