Set all the factors equal to 0 and solve for x.

1) x + 6 = 0

x = -6

2) x + 8 = 0

x = -8

3) x + 15 = 0

x = -15

When the function is graphed, you can see that the function crosses the numbers -15, -8, and -6 on the x-axis. These are the zeros.

Y+5=x+3 in standard form

podryga [215]

Answer: x-y=2

Step-by-step explanation:

y+5=x+3; move variable (x) to the left-hand side and change the sign.

y-x+5=3; move the constant to the right-hand side & change the sign

y+x=3-5; reorder the terms

-x+y=3-5; calculate

-x+y=-2; change the signs on both sides

x-y=2 is your answer! hope this helps!

Which expression represents the correct form for the quotient and remainder, written as partial fractions, of

Oduvanchick [21]

Answer:

$C)~A+ \frac{B}{x-3} +\frac{c}{(x-3)^2}$

Step-by-step explanation:

→ $\frac{(7x^2-40x+52)}{(x^2-6x+9)}$

→ $\frac{7x^2-40x+52}{x^2-2.3x+(3)^2}$

→ $\frac{7x^2-40x+52}{(x-3)^2}$

So, your answer is C

Please help ASAP failing class if i dont answer correct

(See the imagine for reference)
Let’s solve where they have a triangle, so the height is 9 cm, the base is 3 cm:

1/2 • 9 • 3 = 13.5

Since there’s 2 triangles we do:

13.5(2) = 27

Now the rectangle in the middle, where the height is 9cm and the base is 12cm:

12 • 9 = 108

Add up the areas:

108 + 27 = 135
