Answer:
A
Step-by-step explanation:
You basically just factor out the equation using FOIL. You start with the First term 2x and multiply that by 3x. Next, you multiple the 2x with the Outer term which is 5. Then, you multiply the Inner terms 3x and -1 to get -3x. lastly, you use the 5 and -1 and multiply them with each other. The solution would be 6x^2+7x-5 when you combine like terms.

Answer:
B
Step-by-step explanation:
The slope is 4.
Let's find the slope between your two points.
(1,−2); (3,6)
(x1,y1) = (1,−2)
(x2,y2) = (3,6)
Use the slope formula:
m = y2−y1 / x2−x1
= 6− −2 / 3−1
= 8 / 2
= 4
Answer:
m = 4
To add with powers, both the variables and the exponents of the variables must be the same. You perform the required operations on the coefficients, leaving the variable and exponent as they are. When adding with powers, the terms that combine always have exactly the same variables with exactly the same powers
