Answer: 1
Step-by-step explanation:
6 times 2 minus 2y = 10
first 6x2=12
12-2y=10
minus 12 from each side =0
so now you have;
-2y= -2
divide & you get one!

we have
Solve for x
Multiply in cross
Divide by 33 both sides (Division Property of Equality)
Convert to mixed number
3.5*8=28
The answer is 28 m^3
Answer:
x = 2 + 6i, x - 6i.
Step-by-step explanation:
To factor this you need 2 numbers whose product is + 40 and whose sum is -4. There are no such numbers so we could use the method of completing the square:
x^2 - 4x + 40 = 90
x^2 - 4x = -40
(x - 2)^2 - 4 = -40
(x - 2)^2 = -36 - So the roots are complex numbers:
x - 2 = +/-√36
x = 2 + 6i, x - 6i.
