Just explaining instead of using x for the variable I'm going to use t just so u don't get mixed up with the multiplication symbol and the variable.But on your paper you must use d or else you won't receive full credit.
15tx4>50
On this I can't add a greater than and equal to symbol, but that greater than must have a line under it to represent greater than and equal to. Hope this helps
Assuming it pivots around one side length, it should form a cylinder.
Answer:
8x^2-x-8
Step-by-step explanation:
6x^2 + 3x – 9-(- 2x^2 + 4x – 1 )
6x^2 + 3x – 9+2x^2 - 4x + 1
6x^2+2x^2+ 3x- 4x -9+1
8x^2-x-8
Answer:
x = -4 (multiplicity 2)
Step-by-step explanation:
x^2 + 8x + 16 = 0
You need 2 numbers whose product is + 16 and whose sum is +8.
They are +4 and + 4 so the factors are:-
(x + 4)(x + 4)
(x + 4)(x + 4) = 0
x = -4 (multiplicity 2)
(There are 2 zeroes each of value -4)
