Answer:
-2
Step-by-step explanation:
Put the given values of x and y in the equation, and solve for "a".
-40 = a(1 +3)(1 -2)(1 -6) = 20a
-40/20 = a = -2
The value of "a" is -2.
I think it’s 5 I’m not really sure

Answer:
B
Step-by-step explanation:
the product (2x² - 3x - 8)(3x² + 5x + 1) is required
multiply each term in the second factor by each term in the first factor.
= 2x²(3x² + 5x + 1) - 3x(3x² + 5x + 1) - 8(3x² + 5x + 1) ← distribute
= 6 + 10x³ + 2x² - 9x³ - 15x² - 3x - 24x² - 40x - 8
collecting like terms gives
6 + x³ - 37x² - 43x - 8 → B
Answer: 25x^2+15x-4
Step-by-step explanation:
Multply 5x by the other 5x
25x^2
Multiply 5x by 4
20x
Multiply -1 by 5x
-5x
Multiply -1 by 4
-4
Add them together
25x^2+20x-5x-4
Combine like terms
20x-5x=15x
25x^2+15x-4
