So you would get the square root of 6/ the square root of 6 which just = 1
Answer:
530 in ^2
Step-by-step explanation:
The figure given is a triangle
We use the formula for the area of a triangle
A = 1/2 bh where b is the length of the base and h is the height
The height is perpendicular to the base( at 90 degrees)
A = 1/2 ( 26.5) * ( 40)
= 530 in ^2
the answer is B. 2
Both are close to 2 but a little under or a little over
50 = 7x - 6 -Add 6 to both sides of the equation
50 + 6 = 7x - 6 + 6
56 = 7x -Divide both sides by 7
8 = x
Hope this helps you! Happy Thanksgiving!
