Answer:
x = ±i sqrt(3/2)
Step-by-step explanation:
2x^2+7 = 4
Subtract 7 from each side
2x^2+7-7 = 4-7
2x^2 = -3
Divide by 2 on each side
2x^2/2 = -3/2
x^2 = -3/2
There is no real solution, only imaginary solutions
Taking the square root of each side
sqrt(x^2) = sqrt(-3/2)
x = ±i sqrt(3/2)
Answer:
4(7)+4(y)
4(y·7)
4(3+4)+4(y)
Step-by-step explanation:
It is the last answer because both x and y are adding by 1
The formula for volume of a cylinder is V= PI x r^2 x H
r = radius = 1/2 diameter = 1/2*1.8 = 0.9 meters
Height = 25
Volume = PI x 0.9^2 x 25
= PI x 0.81 x 25
= PI x 20.25
= 63.62 cubic meters
