3(x + 5) − 3 = 52 − 2x

Anna11 [10]

Answer: The value of x is 8

Step-by-step explanation:

3(x + 5) − 3 = 52 − 2x

First open the bracket, and do multiplication

3x + 15 - 3 = 52 - 2x

3x + 12 = 52 -2x

Collect like terms, and make the whole expression equal to zero

3x + 12 - (52 - 2x) = 0

3x + 12 - 52 + 2x = 0

3x + 2x + 12 - 52 = 0

5x - 40 = 0

5x = 40

Divide both sides by 5

5x/5 = 40/5

x = 40/5

x = 8

Answer:

$\large\boxed{h=\dfrac{\sqrt{703}}{2}ft\approx13.26ft}$

Step-by-step explanation:

Look at the picture.

Use the Pythagorean theorem:

$leg^2+leg^2=hypotenuse^2$

We have:

$leg=\dfrac{9}{2}ft\\\\hypotenuse=14ft\\\\leg=h$

Substitute:

$\left(\dfrac{9}{2}\right)^2+h^2=14^2$

$\dfrac{81}{4}+h^2=196$ multiply both sides by 4

$81+4h^2=784$ subtract 81 from both sides

$4h^2=703$ divide both sides by 4

$h^2=\dfrac{703}{4}\to h=\sqrt{\dfrac{703}{4}}\\\\h=\dfrac{\sqrt{703}}{\sqrt4}\\\\h=\dfrac{\sqrt{703}}{2}\\\\h\approx13.26$
