Answer:
x = 0 or x = 1/4
Step-by-step explanation:
You are able to factor out 3x² from 12x³ - 3x² to get 3x²(4x-1).
Set everything to zero and solve.
Answer:
Step-by-step explanation:
X² - 3x - 4 = 0
Reverse FOIL method . . .
(x - 4)(x + 1) = 0
one of the paranthesis has to be equal to zero if the other is not . . .
x - 4 = 0
<u><em>x = 4</em></u>
x + 1 = 0
<u><em>x = -1</em></u>
Answer:
x = 4
Step-by-step explanation:
The quadrilateral is a rectangle and opposite sides are congruent, hence
10 + 2x = 18 ( subtract 10 from both sides )
2x = 8 ( divide both sides by 2 )
x = 4
Let, the number = x
Then, x * 130% = 52
x * 1.30 = 52
x = 52/1.30
x = 40
So, the number is less than 52
Hope this helps!
