Answer:
A=90°,B=90°,C=90°,D=90°
Step-by-step explanation:
all of the numbers A-D add up to 360°
Putting the square root of 130 in the calculator you would get around 11.4 which if rounded to the next whole number would be 11. The closest whole number to the square root of 130 is 11.
The product of the sum of two perfect cubes:
a³ + b³ = (a + b)(a² - ab + b²)
The product of the difference of two perfect cubes:
a³ - b³ = (a - b)(a² + ab + b²)
----------------------------------------------------------------------------------------------------------------
Remember to follow FOIL:
(b^2 + 8)(b^2 - 8)
(b^2)(b^2) = b^4
(b^2)(-8) = -8b^2
(8)(b^2) = 8b^2
(8)(-8) = -64
b^4 - 8b^2 + 8b^2 - 64
Combine like terms:
b^4 (-8b^2 + 8b^2) - 64
b^4 - 64
b^4 - 64 is your answer

A ratio is a set of two numbers of comparison. It claims the Volleyball team has 10 OUT OF 16 games. So win to loss, they won 10 games, but there was sixteen games. Meaning they had lost 6 games. So since it's asking about the ratio of WIN to LOSS, it would be 10:6. :-) Hope this helped.
