If x2 = 30, what is the value of x? A. ±60
B. ±15
C. ±square root of 30
D. ±square root of 15

The answer is B. 15

Step-by-step explanation:

x2=30

when you plug 15 in u get the equation 15x2=30

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.

graph them on a graphing calculator, press 2nd trace. select intersect. hit enter until it says answer. ti 84 works best
