Answer:
x = -27 or 1
Step-by-step explanation:
Let z = x^(1/3). Then the equation becomes the quadratic ...
z^2 +2z -3 = 0
(z +3)(z -1) = 0
z = -3 or +1 . . . . values of z that make the factors be zero.
Then
x = z^3
so the two solutions are ...
x = (-3)^3 = -27
x = 1^3 = 1
Answer:
-6 ≥ x
Step-by-step explanation:
x + 6 ≥ 12 + 2x
Subtract x from each side
x-x + 6 ≥ 12 + 2x-x
6 ≥ 12 + x
Subtract 12 from each side
6-12 ≥ 12-12x
-6 ≥ x
Answer:
My answer is 8.428571429 ~ 8.43.
Step-by-step explanation:
First you can find log 5 which is 0.698970004 ~0.7. then you can use it to multiply the numbers in the bracket which will be 0.7x(x-7)=1...which will be 0.7x-4.9=1...then you will collect like terms which will be 0.7x=1+4.9 then it will be 5.9÷0.7 which will be equal to my answer above..Thank you for the question
Answer:
4.03 < 16.5
Step-by-step explanation:

Answer:
The perimeter of the drawing: 18 inches
The perimeter of the actual flower bed: 540 inches
If they were multiplied by 24 instead the actual perimeter of the flower bed would be 432 inches. The effect is that it decreases by 108 inches.
Step-by-step explanation:
Taking the 4 inches and 5 inches and multiplying them by 30 gets 120 by 150. If its a rectangle we will add together all 4 sides to get the perimeter of the actual one.
