Answer:
x = 1 or x = -9
Step-by-step explanation:
Solve for x over the real numbers:
x^2 + 8 x - 9 = 0
Hint: | Solve the quadratic equation by completing the square.
Add 9 to both sides:
x^2 + 8 x = 9
Hint: | Take one half of the coefficient of x and square it, then add it to both sides.
Add 16 to both sides:
x^2 + 8 x + 16 = 25
Hint: | Factor the left hand side.
Write the left hand side as a square:
(x + 4)^2 = 25
Hint: | Eliminate the exponent on the left hand side.
Take the square root of both sides:
x + 4 = 5 or x + 4 = -5
Hint: | Look at the first equation: Solve for x.
Subtract 4 from both sides:
x = 1 or x + 4 = -5
Hint: | Look at the second equation: Solve for x.
Subtract 4 from both sides:
Answer: x = 1 or x = -9
Assuming the question is 45x - 334x = 212
Then the answer is:
45x - 334x = 212
-289x = 212
x = -(212 / 289)
OR
x = -0.73
Answer:
Subtraction Property on Equality.
Step-by-step explanation:
2. 15x + 6 = -24
15x + 6 - 6 = -24-6
15x = -30
Subtraction Property on Equality.
48. 40% of 80 is 32. 80-32=48. Which means there are 32 boys and 48 girls.
