To add or subtract rational expressions with unlike denominators, first find the LCM of the denominator. The LCM of the denominators of fraction or rational expressions is also called least common denominator, or LCD. Write each expression using the LCD.
is the full pizza
So to solve it, you need to minus the amount that Lou ate from the whole pizza
So it would be
To reduce to the lowest terms, you would find the greatest common factor for both the numerator(top) and the denominator(bottom) so 2 is a common factor
2÷2=1 and 8÷2=4
So your answer would be
Answer: is the fraction of the pizza left over
None of the statements are true,
Proof:
Solve for x over the real numbers:
2 x^2 + 12 x = 32
Subtract 32 from both sides:
2 x^2 + 12 x - 32 = 0
2 x^2 + 12 x - 32 = 2 (x^2 + 6 x - 16):
2 (x^2 + 6 x - 16) = 0
Divide both sides by 2:
x^2 + 6 x - 16 = 0
x = (-6 ± sqrt(6^2 - 4 (-16)))/2 = (-6 ± sqrt(36 + 64))/2 = (-6 ± sqrt(100))/2:
x = (-6 + sqrt(100))/2 or x = (-6 - sqrt(100))/2
sqrt(100) = sqrt(4×25) = sqrt(2^2×5^2) = 2×5 = 10:
x = (-6 + 10)/2 or x = (-6 - 10)/2
(-6 + 10)/2 = 4/2 = 2:
x = 2 or x = (-6 - 10)/2
(-6 - 10)/2 = -16/2 = -8:
Answer: x = 2 or x = -8
-6z = 72
Divide both sides by -6
-6z = 72
/-6 /-6
z = -12
Your distance(d) is 1,814.4
1814.4 m = 5.6t square
then you square root 5.6t
the square root eliminates the square
you square root 1,814.4 m
(I rounded 42.6) then divide 42.6 by 5.6
(I rounded 7.6)
