Answer:
When you multiply (5x² - 3x)(8x²+ 4x), then you will get 40x⁴ - 4x³ - 12x²
Step-by-step explanation:
(5x² - 3x)(8x² + 4x)
Multiply 5x² to (8x² + 4x) and multiply -3x to (8x² + 4x).
40x⁴ + 20x³ - 24x³ - 12x²
Combine like terms and don't forget to put the equation in standard form. This means that the exponents are going to be in descending order.
40x⁴ - 4x³ - 12x²
So, your answer will be letter choice A.

Answer:
x=4.875
y=-0.25
Step-by-step explanation:
4x – 2y = 10
2x-y=10
y=2x-10
4x + 6y = 18
2x+3(2x-10)=9
8x=39
x=4.875
y=2(4.875)-10
y=-0.25
