Answer:
x = -5 ±4sqrt(3)
Step-by-step explanation:
(x + 5)^2 = 48
Take the square root of each side
sqrt((x + 5)^2) = ±sqrt(48)
x+5 = ±sqrt(16*3)
x+5 = ±4sqrt(3)
Subtract 5 from each side
x = -5 ±4sqrt(3)
It’s - ( - 3 ) because a negative times a negative equals a positive so it wouldn’t be - ( 3 ) because it would turn into a negative number and - ( - 3 ) would be positive
53
when the first decimal number is 4 or below, then you leave the whole number as it is, and get rid of the decimals.
Answer:
20x-12
Step-by-step explanation:
Given:
7(3x−1)−(x+5)
Step 1: Distribute the Negative Sign:
=7(3x−1)+−1(x+5)
=7(3x−1)+−1x+(−1)(5)
=7(3x−1)+−x+−5
Step 2: Distribute:
=(7)(3x)+(7)(−1)+−x+−5
=21x+−7+−x+−5
Step 3: Combine
=21x+−7+−x+−5
=(21x+−x)+(−7+−5)
=20x+−12
