Answer:
0.25
Step-by-step explanation:
12x = 3
x = 0.25
Y² + 2 y - 2x - 3 = 0
x + 3 = y² + 2 y
2 x + 3 = y² + 2 x + 1 - 1
2 x + 3 = ( y + 1 )² - 1
2 x + 3 + 1 = ( y + 1 )²
Answer:
2 ( x + 2 ) = ( y + 1 )²
Answer:
K=10
Step-by-step explanation:
So first distribute
3x-12=18
add 12 on both sides
3x=30
Divide 3 on each side
x=10
Answer:
(x + 2)(x² - 2x + 4)
Step-by-step explanation:
x³ + 8 ← is a sum of cubes and factors in general as
a³ + b³ = (a + b)(a² - ab + b²), thus
x³ + 8
= x³ + 2³
= (x + 2)(x² - 2x + 4)
First distribute the negative through the parenthesis on the left and the 2 on the right.
-5 -15y +1 = 14y -32 - y
Combine like terms on the right and left
-4 -15y = 13y -32
Now move the variables to one side and the constants to the other.
Subtract 13y from both sides
-4 -28y = -32
Add 4 to both sides
-28y = -28
Divide both sides by -28
y = 1
