Answer:
A and C.
Step-by-step explanation:
to get rid of the square root & n, you would have to multiply it by n on both sides of the equation, giving you r^n=a.
also to get rid of the square root & n, you can also multiply both sides of a and r by the exponential fraction with n as the denominator:
![\sqrt[n]{a} =r \\(a)^\frac{1}{n} = r\\a\frac{1}{n} = r](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Ba%7D%20%3Dr%20%5C%5C%28a%29%5E%5Cfrac%7B1%7D%7Bn%7D%20%3D%20r%5C%5Ca%5Cfrac%7B1%7D%7Bn%7D%20%3D%20r)
As you can probably tell, this is a 30, 60, 90 triangle. That means the degree measures are 30, 60, and 90. These are special triangles. For every 30, 60, 90 triangle in the world, the shorter leg (in your case, x) is ALWAYS two times shorter than the hypotenuse (6). 6/2=3, so x=3. Also, the longer leg for a 30, 60, 90 triangle is always equal to the shorter leg times the square root of 3. So, 3 times the square root of 3 is about 5.2. So, y=5.2. Hope it helps!
Answer:
x = 5
Step-by-step explanation:
x/2 = 15/6
6 * x = 15 * 2
6x = 30
x = 30 / 6
x = 5
Answer:
1.4x - 1.55
Step-by-step explanation:
We have to simplify the expression as 0.5(1.1 - 2x) + 2.4x - 2.1
Now, 0.5(1.1 - 2x) + 2.4x - 2.1
= 0.5 × 1.1 - 0.5 × 2x + 2.4x - 2.1 {Using the distributive property of multiplication}
= 0.55 - x + 2.4x - 2.1
= 1.4x - (2.1 - 0.55)
= 1.4x - 1.55 ( Answer )
