Answer:
x = -1 and x = 4
Step-by-step explanation:
Step 1: Get everything to one side of the equation so it's set equal to zero..
-x² + 4x = x - 4 becomes...
-x² + 3x + 4 = 0 (subtract x and add 4 to both sides)
x² - 3x - 4 = 0 (divide both sides by -1, we want the x² term to be positive)
(x - 4)(x + 1) = 0 (factor)
so
x - 4 = 0, then x = 4
and
x + 1 = 0, then x = -1
Answer:
s=4
Step-by-step explanation:
area of square is side*side
so that means s*s=16
so s = 4
(1.) Part A
The Yellow Chalk because when you turn 2/6 into a new fraction (double it) its 4/12 and 4/12 is bigger than 3/12.
(2.) Part B
It's true because 5/12 is less than half of the bucket because the other half is 7/12

Answer: the original tube contained 12 ounces.
Step-by-step explanation:
Let x represent the number of ounces of lotion that was in the original tube.
The new bottle says you get 30% more than the amount in the original tube. The number of ounces of lotion that makes 30% is
30/100 × x = 0.3 × x = 0.3x
The new, larger tube of lotion contains 15.6 ounces. This means that the number of ounces of lotion in the new tube is expressed as
x + 0.3x = 15.6
1.3x = 15.6
x = 15.6/1.3
x = 12
