The length of a rectangle is the width minus 3 units. The area of the rectangle is 40 units. What is the width, in units, of the

Eva8 [605]

The width of rectangle is 8 units.

Step-by-step explanation:

Given,

Area of rectangle = 40 units

Width = w

Length = w-3

Area = Length * Width

$40=(w-3)*w\\40=w^2-3w\\w^2-3w=40\\w^2-3w-40=0$

Factorizing the equation

$w^2-8w+5w-40=0\\w(w-8)+5(w-8)=0\\(w-8)(w+5)=0$

Either,

w-8=0 => w=8

Or,

w+5=0 =>w= -5

As width cannot be negative, therefore

Width of rectangle = 8 units

The width of rectangle is 8 units.

Was I right for 46 but 47 I need help with

Julli [10]

You are not right on #46. Since he is going 50 miles in 50 minutes, that means that he is going a mile a minute. That means in an hour, he will have gone 60 miles. That means he will have been going 60 mph, so the correct answer is (4)

I cannot help you with 47 because you did not include the picture it shows.

anastassius [24]

X=cost of one box of popcorn.
we can suggest this equation:

3x+1.75=9.25

3x=9.25-1.75
3x=7.5
x=7.5/3
x=2.5

Answer: the equation to find the cost of one box of popcorn is 3x+1.75=9.25, and the cost of one box of popcorn is $2.5.
