X^2+4x-12=0
(x+6)(x-2)=0
X can equal -6 and 2.
x=-6
x=2
Answer:
the one for the finding the height is 3.3, the one with 7 as the height is 351.86, and the one with 3 as the height is 150.8
Step-by-step explanation:
h=V
πr2=41.5
π·22≈3.30247
V=πr2h=π·42·7≈351.85838
V=πr2h=π·42·3≈150.79645
Answer:
3.) (x + 5) (x - 6)
Step-by-step explanation:
Factor the following:
x^2 - x - 30
Hint: | Factor x^2 - x - 30 by finding two numbers whose product is -30 and whose sum is -1.
The factors of -30 that sum to -1 are 5 and -6. So, x^2 - x - 30 = (x + 5) (x - 6):
Answer: (x + 5) (x - 6)
Answer:
7x-1/22 = 3x+1/10
Multiply both sides of the equation by the Lowest common Multiple of the denominators(22 and 10). This is done to clear the fractions.
The LCM of 22 and 10 is 110
So
110 x(7x-1/22) = 110 x (3x+1/10)
110/22 =5
110/10 = 11
So the eqn now becomes
5(7x-1) = 11(3x+1)
Opening the parentheses
35x - 5 = 33x + 11
Collect Like Terms
35x - 33x = 11 + 5
2x = 16
x= 8.
3y=4
4y=3
is that what you mean?
