Question

Find the value of x. If necessary, round to the nearest tenth

Answer 1

A) 7.0 in.
B) 11.9 in.
C) 9.9 in.
D) 14.0 in.

Answer 2

base *height*1/2=A
x*x*1/2=49

Answer 3

Before you solve for x, you need to simplify the equation, which becomes x^2*1/2=49.

Answer 4

To solve for x, you would use order of operations, and multiply by sides by 2, which makes x^2=98. To find x, you find the square root of both sides, which gives you x= square root of 98. The square root of 98 is about 9.9, so 9.9 is your answer

Answer 5

\[\frac{x^2}{2}=49 \]\[x=7 \sqrt{2} \]
