Answer:
150.72
Step-by-step explanation:
3² × 3.14 × 6 - 1² × 3.14 × 6 = (3² - 1²) × 3.14 × 6 = 150.72
The answer is d because 12c=20 = c=65/12 divide by both sides
Answer: A - sin 63
Step-by-step explanation:
Answer:
(3/7)^7
Step-by-step explanation:
When multiplying exponents we can use the formula: a^m x a^n = a^m+n.
In this case, we can plug in 3/7 for a, and their respective exponents as m and n.
(3/7)^3 x (3/7)^4= (3/7)^3+4= (3/7)^7
Hope this helps!

By the way I looked this up but heres the best ive got
<span>Simplifying
(-1x + 27) + (16x + 4) = 0
Reorder the terms:
(27 + -1x) + (16x + 4) = 0
Remove parenthesis around (27 + -1x)
27 + -1x + (16x + 4) = 0
Reorder the terms:
27 + -1x + (4 + 16x) = 0
Remove parenthesis around (4 + 16x)
27 + -1x + 4 + 16x = 0
Reorder the terms:
27 + 4 + -1x + 16x = 0
Combine like terms: 27 + 4 = 31
31 + -1x + 16x = 0
Combine like terms: -1x + 16x = 15x
31 + 15x = 0
Solving
31 + 15x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-31' to each side of the equation.
31 + -31 + 15x = 0 + -31
Combine like terms: 31 + -31 = 0
0 + 15x = 0 + -31
15x = 0 + -31
Combine like terms: 0 + -31 = -31
15x = -31
Divide each side by '15'.
x = -2.066666667
Simplifying
x = -2.066666667</span>
