Answer:
x = 10 or x = 2
Step-by-step explanation:
Solve for x:
x^2 - 12 x + 20 = 0
Hint: | Solve the quadratic equation by completing the square.
Subtract 20 from both sides:
x^2 - 12 x = -20
Hint: | Take one half of the coefficient of x and square it, then add it to both sides.
Add 36 to both sides:
x^2 - 12 x + 36 = 16
Hint: | Factor the left hand side.
Write the left hand side as a square:
(x - 6)^2 = 16
Hint: | Eliminate the exponent on the left hand side.
Take the square root of both sides:
x - 6 = 4 or x - 6 = -4
Hint: | Look at the first equation: Solve for x.
Add 6 to both sides:
x = 10 or x - 6 = -4
Hint: | Look at the second equation: Solve for x.
Add 6 to both sides:
Answer: x = 10 or x = 2
51 feet you have to multiple 32 by 8 it will give you 256 and then divide 256 and 5 and you get 51
Answer:
No it is not
Step-by-step explanation:
A number is divisible by 4 if the last two digits are divisible by 4. Since the last two digits "90" are not divisible by 4, then 78990 is not divisible by 4.
The value of p = 11
y = 5x + p
1 = 5(-2) + p
1 = -10 + p
11 = p
