7x7(12+9) to the power of 3
Answer:
\frac{2x^2}{3} =24
Step-by-step explanation:
times both sides by 3
2x²=72
divide both sides by 2
x²=36
sqrt both sides
x=+/-6
x=-6 or 6
-6<6 so -6 is the smallest solution
Answer:
symmetrical means the sides are the same
Answer:
17.71359378 = x
Step-by-step explanation:
cos theta = adj/ hyp where adj means adjacent side and hyp means hypotenuse
cos 49 = x /27
Multiply each side by 27
27 cos 49 = x
17.71359378 = x
1. x = 7, -7
5. d = 5, -5
7. m = 10, -16
