S=2(lw+lh+wh) solve for w

Mathematics

we have

s=2(lw+lh+wh)

Solve for w means that clear variable w

s=2(lw+lh+wh)\\s=2lw+2lh+2wh

Group terms that contain the variable w, and move the other terms to the opposite side of the equation

(s-2lh)=(2lw+2wh)

Factor the variable w

(s-2lh)=w(2l+2h)

Divide both sides by (2l+2h)

(s-2lh)/(2l+2h)=w(2l+2h)/(2l+2h)

w=(s-2lh)/(2l+2h)

therefore

<u>the answer is</u>

w=(s-2lh)/(2l+2h)

The expression y2 – 10y + 24 has a factor of y – 4. What is another factor of y2 – 10y + 24?
charle [14.2K]
We may answer the question above by dividing the expression y² - 10x + 24 with the given factor, y - 4. The division would give an answer of y - 6. Thus,

                                <span>y² - 10x + 24 = (y - 4)(y - 6)

The answer is the fourth choice, y - 6.</span>
