The correct answer would be Choice A.

The find the volume of the box, you need to multiply the L by W by H. Both the length and width have been reduced by 2 x's. And the height will be just x.

Therefore, LWH becomes (40 - 2x)(32 - 2x)x

Answer:

(a) (40−2x)(32−2x)x

Step-by-step explanation:

A box without a top is made from a rectangular piece of cardboard, with dimensions 40 inches by 32 inches, by cutting out square corners with side length x inches. both sides are cut by x inches

Length of the box = 40 -x-x= 40-2x inches

Width of the box = 32-x-x= 32-2x inches

height of the box is the side length = x inches

Volume of the box = length * width * height

= (40-2x)(32-2x)x

A farmer has 7 3/4 rows of radishes in one field, 4 3/4 rows of radishes in another field, and 6 1/4 rows of radishes in a third
Gala2k [10]

Answer:

  A. 18 3/4

Step-by-step explanation:

It is convenient to rearrange the sum to make it easier to compute:

  7 3/4 + 4 3/4 + 6 1/4 = (7 3/4) +(4 +6) +(3/4 +1/4)

  = 7 3/4 + 10 + 1

  = 18 3/4

The farmer has 18 3/4 rows of radishes altogether.

Hatshy [7]
Wait what's the question tho?
is it if this point is on the line?

-y=mx+b
3=-6(6)-3
-3=-36-3
-3 does not equal -39
hence, point is not on the line

LuckyWell [14K]
To find the area, you will need to times the length with the width. 

So,

2.25*1.8=4.05 meters 

1m=100cm

4.05m=405cm

Hope this helps.
