The formula for the surface area is 2(lw + lh + wh). So all you have to do is plug the values in. Box A:2(lw + lh + wh)2( (4x6) + (4x25) + (6x25) ). 2(24+100+150)2(274)548=Surface Area
Box B:2(lw + lh + wh)2( (9x5) + (9x11) + (5x11) ). 2(45+99+55)2(199)398=Surface Area
Box C:2(lw + lh + wh)2( (10x5) + (10x8) + (5x8) ). 2(50+80+40)2(170)340=Surface Area]

Use function notation to write the equation of the line

blondinia [14]

$f(x)=mx+b\to y=mx+b$

We have two points:

$(-3,\ 0);\ (-4,\ 7)$

The point slope form of the line:

$y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}$

Substitute

$m=\dfrac{7-0}{-4-(-3)}=\dfrac{7}{-1}=-7$

$y-0=-7(x-(-3))\\\\y=-7(x+3)\\\\y=-7x-21$

Answer:

$f(x)=-7x-21$

7 - 8x + 22<br> What does X equal!<br> x =?

VashaNatasha [74]

Answer: x = -3.625 or -29/8

Step-by-step explanation:

7-8x+22

1. -Set it equal to 0.

7-8x+22=0

2. Subtract 7 and 22 from both the left and right sides.

7-8x+22=0

-7 -22 -7 -22

8x = -29

4. Divide both sides by 8.

8x=-29

8 8

x= -3.625

Leave it in fraction form if decimal is unacceptable.

hope this helps.
