Answer:
x^2+3x+2x+1 is meant to be x^2 +5x+1
Answer:
When x = -2 or when x = 7
Step-by-step explanation:
x+2 is a factor in the denominator. If x = -2, the factor becomes zero.
x-7 is a factor in the denominator. If x = 7, the factor becomes zero.
We can't have zero as a factor in a denominator because division by zero is not defined. It doesn't have any meaning.
What is the value of X?
Simplify:
8x - 10 - 4x = - 12(12x - 20)
Simplify both sides:
8x - 10 - 4x = - 12(12x -20)
8x + - 10 + - 4x = (- 12)(12x) + ( -12)(- 20)
(Distribute:)
8x + - 10 + - 4x = 144x 240
(8x + - 4x) + ( -10) = - 144x + 240 (Combine Like Terms:)
4x + - 10 = - 144x + 240
4x - 10 = - 144x + 240
Add - 144x to both sides:
4x - 10 + 144x = - 144x + 240 + 144x
148x - 10 = 240
Add 10 to both sides:
148x - 10 + 10 = 240 + 10
148x = 250
Divide both sides by 148
148x/148 = 250/148
x = 125/74
Answer: x = 125/74 (Decimal: 1.689189)
Hope that helps!!!!
