X = 7 / sin(45)
x = 7 / sqrt(2)/2
x = 7 sqrt(2)
Answer
8
Explanation
The absolute value of a negative number turns into a positive
The answer is B. 3.3 Liters.
3.5 Quarts is 3.31224 liters.
we know that 1 gallon = 4 quarts so...
17 gallons of root beer + 12 gallons of punch = 29 gallons in total
29 gallons ÷ 4 = 7.25 quarts
so she needs 7 bottles of quarts for her 29 total gallons.
Answer:
x = - 4 ± 2
Step-by-step explanation:
Given
f(x) = x² + 8x + 4
To find the zeros let f(x) = 0, that is
x² + 8x + 4 = 0 ( subtract 4 from both sides )
x² + 8x = - 4
To solve using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(4)x + 16 = - 4 + 16
(x + 4)² = 12 ( take the square root of both sides )
x + 4 = ±
= ± 2
( subtract 4 from both sides )
x = - 4 ± 2
Thus the zeros are
x = - 4 - 2
and x = - 4 + 2
