Ok so ... the answer is B:264 because you multiply all the numbers because volume = l x w x h... which also is 6 x 11 x 4 and that’s how I got B :)

The volume of the shipping box needs to be 1,144 cubic inches. The equation that models the volume of the shipping box is 8(n +
Snezhnost [94]

Answer:

see below

Step-by-step explanation:

8(n + 2)(n + 4) = 1,144

FOIL

8(n^2 +2n+4n+8) = 1144

Divide each side by 8

8/8(n^2 +2n+4n+8) = 1144/8

(n^2 +2n+4n+8) = 143

Combine like terms

n^2 +6n+8 = 143

Subtract 143 from each side

n^2 +6n+8 -143= 0

Combine like terms

n^2 +6n -135 =0

Factor

What two terms multiply to -135 and add to 6

-9*15 =-135

-9+15 = 6

(n-9) (n+15) =0

Using the zero product property

n-9 =0    n+15=0

n = 9   n=-15

The length cannot be negative so n = -15 cannot be  a solution

n =9

Dana has 4 hours to spend training for an upcoming race. She completes her training by running full speed the distance of the ra
Sedaia [141]

Answer:

2hrs 40 minutes

Step-by-step explanation:

The formula for distance is expressed as:

d=st, s=speed, t=time

#The time taken to run:

d=st\\\\t=d/s\\\\t_r=d/8

#The time taken to walk:

d=st\\\\t=d/s\\\\t_w=d/2

#Since the distances are the same:

d_r=8t_r,d_w=2t_w\\\\8t_r=2t_w\\\\t_r+t_w=4->t_w=4-t_r\\\\\therefore8t_r=2(4-t_r)\\\\8t_r=8-2t_r\\\\t_r=1\frac{1}{3} \hrs\\\\t_w=4-1\frac{1}{3}=2\frac{2}{3}\ hrs

Hence, Dana spends 2hrs 40 minutes walking back

¡¡¡40 POINTS!!!HELP ASAP!!
Nataly_w [17]
Hi there!

To start, we can use the two points to find the slope using the formula y2-y1/x2-x1. Just sub in the points and solve!

-0.5-0.5/3-(-3)
-1/6
Sub that into the formula y-mx+b for m, and use one of the points for x and y - solve for b and you get your equation. 

y=mx+b
y=-1/6x+b
0.5=-1/6*-3+b
0.5=-0.5+b
0.5+0.5=b
b=1

Therefore your equation is y=-1/6x+1

Hope this helps!
