24x + 8 would be the anwser
Step-by-step explanation:
x = 3 and y = 5.
1: 2xy
2 x 3 x 5
=30
2: 6y divided by x
6 x 5 / 3
30/3
=10
3:4y- x
4 x 5 -3
20-3
=17
4:Y(to the power of two) -7x +2
5^2 -7 x 3 + 2
25-7x3+2
25-21+2
25-19
=6

Answer:
-11
Step-by-step explanation:
The answer to the first one sould be -11
2x^3 +5x^2−x−6
Write 5x^2 as 4x^2 + x^2......and we have.....
2x^3 + 4x^2 + x^2 - x - 6
2x^2 ( x + 2) + ( x + 2)(x - 3)
(x + 2) [ 2x^2 + x - 3]
(x + 2) (2x +3) (x - 1)
x^3−4x^2−3x+18 = 0
Using some synthetic division, we have
3 [ 1 - 4 -3 18 ]
3 -3 -18
_______________
1 -1 -6 0
The remaining polynomial is x^2 - x - 6 which factors as (x - 3) ( x + 2)
So .... the factored form is (x - 3) ( x - 3) ( x + 2) = ( x + 2) ( x - 3)^2 = 0
Y=7
X=-3
