Part A Simplify:

Answer is - 12b + 6c + 18

Part B

Answer is (D)

Factor/simplify
- 12b + 6c + 18

6(- 2b + c + 3)
= (6)(- 2b + c + 3)
= (6)(- 2b ) + (6)(c) + (6)(3)
= - 12b + 6c + 18

therefore,- 12b + 6c + 18; Factored in GCF is 6(-2b + c + 3)

- 12b + 6c + 18
reorder the terms
18 + 12b + 6c

Factor out the GCF " 6"
6(3 + 2b + c)

Final Result:
6(3 + 2b + c)

Hope this helps

WORDED QUADRATIC EQUATION!!! PLS HELP <br><br> MOSTLY NUMBER 5 PLS

pav-90 [236]

Answer:

7,11

Step-by-step explanation:

The width is x. x+4= the length. The area is side times side, so it’s

x × (x+4) = 77

We can simplify this to:

x × x + x × 4 = 77

x^2 + 4x = 77

x^2 + 4x - 77 = 0 This is a quadratic equation. So we can solve using the quadratic formula:

x = $\frac{-4\pm\sqrt{4^2-4\cdot1\cdot-77}}{2\cdot1}$ ->

$\frac{-4\pm18}{2}$

$\frac{14}{2} \implies7$

That’s the positive solution and that’s x, the width. So the width is 7 and the length is 7+4=11
