Answer:

B. x = -5 +/- √30.

Step-by-step explanation:

2x^2 + 20x = 10

2(x^2 + 10x) = 10

2[ (x + 5)^2 - 25 ] =10

2(x + 5)^2 - 50 = 10

2(x + 5)^2 = 60

(x + 5)^2 = 30

x + 5 = +/- √30

x = -5 +/- √30.

What is the area of this triangle?

Ganezh [65]

Answer:

$\boxed{\bold{120 \ Units^2}}$

Step By Step Explanation:

Area Of Triangle: $\bold{\frac{1}{2}Base \ \cdot \ Height}$

Base: 10

Height: 24 (This triangle has a right angle, so we use the height based off of the 90° angle, which is 24)

Insert Numbers Into Equation

$\bold{\frac{1}{2}10 \ \cdot \ 24}$

$\bold{\frac{1}{2}}$ 10 = 5

$\bold{5 \ \cdot \ 24 \ = \ 120}$

➤ $\boxed{\bold{Mordancy}}$
