Answer:

The answer is 4

Step-by-step explanation:

Set them equal so it would be X-3= -X+5 then add the negative X to get

2x-3=5 then add the -3 to 5 and get

2x=8 then divide 2 from both sides to get

x=4

If 1 factor of 6x3 + 23x2 − 6x − 8 is (x + 4), what are the other 2 factors?

spin [16.1K]

Use synthetic division to find the quadratic:

-4 | 6 23 -6 -8
6 -24 4 | 8
—————-
6 -1 -2 | 0 = 6x²-x-2 = (3x+1)(2x-1)

So the other two factors are 3x+1 and 2x-1.

The sum of two nonnegative numbers is 50. What is the maximum value of the product of these two numbers ?

Umnica [9.8K]

Answer:

625

Step-by-step explanation:

Let two number be x and (50-x).

The product of numbers be x(50-x).

P = 50x-x²

For maximizing the product,

$\dfrac{dP}{dx}=0\\\\\dfrac{d}{dx}(50x-x^2)=0\\\\50-2x=0\\\\50=2x\\\\x=25$

So, the maximum product, P = 50(25)-(25)²

P = 625

Hence, the maximum value of the product of these two numbers is 625.
