Answer: The first radio button choice 8/3 * m^8
Steps:
120 (m^ 16) / 45 (m^8) =
120/45 * (m^16)/(m^8) =
Simplify 120/45 (15 or 5 *3 divides each). Since base "m" is same in both terms simply subtract exponents.
8/3 ( m^(16 - 8)) =
8/3 * m^8

Answer:
Circumference = 2 x pi x r
Radius, r = 7/2
Circumference = 2 x 22/7 x 7/2
= 22 cm
Answer:
A
Step-by-step explanation:
Given
x² - x = 30
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 
)x + 
= 30 +
(x - )² = 
Take the square root of both sides
x - = ± 
= ± 
Add to both sides
x = ± , thus
x = - = - 5
x = + = 6
This is the graph for the equation y=2x-4.
