Find the product.
(x-3)(x+5)

Answers

Answer 1

Answer:

x2+5x-3x-15=x2+2x-15

Step-by-step explanation:

(x)(x)=x2,(x)(5)=5x

(-3)(x)=-3x,(-3)(5)=-15

Answer 2

Answer: X^2 + 8x -15

Step-by-step explanation:

Use the foil method.

First, outer, inner, last

Multiply the first numbers inside each parenthesis. X*X = x^2

Next multiply the outer number in each parenthesis. X*5 = 5x

Then multiply the inner numbers of the parenthesis. -3*x= 3x

Finally multiply the last numbers in the parenthesis. -3*5 = -15

Now add all of these together

X^2 + 5x + 3x + -15

Combine like terms

X^2 + 8x -15

X can be solved from here, however it does not seem that you are asked to solve for x

Find the x- and y-intercepts of the graph of the linear equation 3x+6y=2

Answers

Answer:

x-intercept: 2/3

y-intervept: 1/3

Step-by-step explanation:

3x + 6y = 2

You're supposed to 'cover them'.

If you want to find the x-intercept, you will cover 6y like it doesn't exist. So now, it's going to be:

3x = 2

You'll then solve for x, which will be the x-intercept

3x/3 = 2/3 (Divide both sides by 3)

x = 2/3 or 0.66... (the 6 goes on forever)

Now, to find y, you'll act like x doesn't exist. It's going to be:

6y = 2

Solve for y, which will be the y-intercept

6y/6 = 2/6 (Divide both sides by 6)

y = 1/3 or 0.33... (the 3 goes on forever)

If you put them as coordinates:

x-intercept: (2/3, 0)

y-intercept: (0, 1/3)

D. x=72
30 POINTS TO THE RIGHT ANSWER AND BEST EXPLANTION.

Answers

Answer: D. x=72

Step-by-step explanation:

With the equation x/8-6=3  we can start solving by first moving the "-6"

                 x/8-6(+6)=3(+6)

                 x/8=9             <-- Rewrite equation after adding "6" to both sides

                 x/8(*8)=9(*8)  <--- Multiply both sides by 8

                 x=72              <-- After multiplying, solution is found
