Determine the product of each set of polynomials (2x-3)(4x+5)
1 answer:
<span>(2x-3)(4x+5)
We must use distributive property to find the product.
First multiply 2x and 4x, then 2x and 5.
Second multiply -3 and 4x, then -3 and 5.
Finally combine like terms.
8x^2 + 10x - 12x -15 = 8x^2 - 2x - 15 is the answer
Don't forget when multiply exponents, you're adding them. For example 2x times 4x equals 8x^2. I'm adding x^1 and x^1 which equals x^2

I think it’s 30.15 or 43.85 if nether I’m dumb
Answer:
25x + 35(2x) = 380
25x + 70x = 380
95x = 380 so
x = 4
then i think that mean it might be 8 then im not completly sure
190 is the correct answer
