Answer:
- 3x² + x + 5
Step-by-step explanation:
Given
(4x + 5) + (- 3x² - 3x) ← remove parenthesis
= 4x + 5 - 3x² - 3x ← collect like terms
= - 3x² + (4x - 3x) + 5
= - 3x² + x + 5
There are 4! = 24 poosible permutations of the four letters. Let the letters be A, B, C and D. Two permutations will have only letter A in the correct envelope, two more permutations will have only letter B in the correct envelope, two more will have only letter C in the correct envelope and two more will have only letter D in the correct envelope. Therefore 8 out of the 24 possible permutations will have only one letter with the correct address. The required probability is 8/24 = 1/3.
Answer:
v² -5v -24
Step-by-step explanation:
(v +3)(v - 8)
FOIL
Front
v x v = v²
Outer
v x -8 = -8v
Inner
3 x v = 3v
Last
3 x -8=-24
put it together in standard form (highest exponent to lowest)
v² - 8v +3v -24
combine like terms
v² -5v -24
<span>2x^2-x=3
</span><span>2x^2-x - 3 = 0
</span><span>(2x - 3)(x + 1) = 0
2x - 3 =0
x = 3/2
x + 1 =0
x = -1
answer

x = -1 and x = 3/2
