Answer:

${x}^{2} + 9x + 20$

Step-by-step explanation:

1) Use FOIL method: (a + b) (c + d) = ac + ad + bc + bd.

${x}^{2} + 5x + 4x + 20$

2) Collect like terms.

${x}^{2} + (5x + 4x) + 20$

3) Simplify.

${x}^{2} + 9x + 20$

Therefor, the answer is x² + 9x + 20.

-2(bx-5)=16 The value of x in terms of b is? That value of x when b is 3?

grin007 [14]

Answer:

Step-by-step explanation:

Let's solve for b.

−2(bx−5)=16

Step 1: Add -10 to both sides.

−2bx+10+−10=16+−10

−2bx=6

Step 2: Divide both sides by -2x.

−2bx/−2x=6/−2x

b=−3x

Answer:

b=−3x

———————————————————

Let's solve for x.

−2(bx−5)=16

Step 1: Add -10 to both sides.

−2bx+10+−10=16+−10

−2bx=6

Step 2: Divide both sides by -2b.

−2bx/−2b=6/−2b

x=−3b

Answer:

x=−3b

Math slope intercept form

ololo11 [35]

Answer:

$-\frac{1}{4}$

Step-by-step explanation:

To find the slope intercept form you need to use the formula:

$\frac{y_2-y_1}{x_2-x_1} =slope$

(0,2) (8,0)

(x1,y1) (x2,y2)

$\frac{0-2}{8-0}=\frac{-2/2}{8/2} =-\frac{1}{4}$
