Answer:
X= 3 or x=-17
Step-by-step explanation:
1. Simplify both sides of the equation
2. Subtract 4X to the second power +56X +192 from both sides
3. Factors the left side of the equation
4. Set factors equal to zero
Answer:
120 cans
Step-by-step explanation:
1 carton = 24 cans
therefore, 5 * 24 = 120
Subtract x^2 from both sides
x^2 + 3x - 7 = 5x + 39
Subtract 5x from both sides
x^2 - 2x - 7 = 39
Add 7 to both sides
x^2 - 2x = 46
Complete the square by adding (b/2)^2 to both sides, b = ( -2)
(-2/2) = -1, then square that (-1)^2 = 1
x^2 - 2x + 1 = 46 + 1
Simplify the expression by factoring
(x - 1)^2 = 47
Take square root on each side
x - 1 = (sqrt (47))
Solve for x
x = 1 + (sqrt (47))
Since 47 is prime, 47 cannot be broken down by the square root and this is the answer to your problem.
Answer:
100
Step-by-step explanation:
hundreds are 0, 100, 200, 300, etc
it's between 0 and 100 but closer to 100
C. (X-2)(x-5)C. Y=(x-2)(x-5)
