Answer:
C
Step-by-step explanation:
Your answer would be 518 Cubic inches.
18.5 * 7 = 129.5
129.5 * 8 = 1036 (Full planter aka not what we want)
If we take the height and divide it be 2 then we would get 4in (halfway full)
So 129.5 * 4 = 518 Cu.
I hope I helped!
Solutions are 3 and - 5.
Step-by-step explanation:
Step 1:
Given equation is 3x² + 6x = 45. Factorize the equation to get the solutions.
⇒ 3x² + 6x - 45 = 0
⇒ x² + 2x - 15 = 0
⇒ x² + 5x - 3x - 15 = 0 (Product and Sum Method where product of coefficients = - 15 and sum = 2)
⇒ x (x + 5) - 3(x + 5) = 0
⇒ (x - 3)(x + 5) = 0
⇒ x = 3, - 5
