The area of the triangle above is 21. What is the value of x ?

Veronika [31]

Answer:

Step-by-step explanation:

area = ½×base×height

21 = ½(x+1)x

42 = (x+1)x

x² + x - 42 = 0

(x+7)(x-6) = 0

x = -7, 6

-7 is an extraneous solution, so x = 6

Solve the equation for x.

Advocard [28]

ANSWER

D. x=55

EXPLANATION

The given radical equation is

$\sqrt{x - 6} + 3 = 10$

Add -3 to both sides

$\sqrt{x - 6} = 10 - 3$

$\sqrt{x - 6} =7$

Square both sides.

${ (\sqrt{x - 6})}^{2} = {7}^{2}$

$x - 6 = 49$

Solve for x to get:

$x = 49 + 6 = 55$
