A rectangular pen has a length 4 feet greater than its width. Find the area
Bas_tet [7]

Answer:

b. x^2+4x

Step-by-step explanation:

So since you don't know the width, you can just represent it as a variable, and in this case that variable will be "x". Now using this variable we can use it to represent the length since there is a relationship between the width and length which is given. Since the length is 4 feet greater than the width, we can represent the length as (x+4). Now to find the area, we simply multiply the length * width, which is x * (x+4) = x^2 + 4x

Determine the midpoint given 2<br> points.<br> (6,-10), (10,7)?
NISA [10]

Hey there! I'm happy to help!

To find the x-value of the midpoint, you add the x values and divide by 2.

6+10=16

16/2=8

And for the y value, you do the same thing but with the y values.

-10+7=-3

-3/2=-3/2

Therefore, our midpoint is (8,-3/2).

Have a wonderful day! :D

Explain how to find the surface area of a can of fruit with a height of 80 mm and a diameter of 60 mm. Give the area in your exp
sdas [7]

Answer:

S=6600\pi \text{ mm}^2

S\approx 20724 \text{ mm}^2

Step-by-step explanation:

A can of fruit is geometrically a cylinder.

We are talking about the <u>surface area of a cylinder</u>:

S=2\pi rh+2\pi r^2

\pi \approx 3.14

r: \text{radius}

h: \text{height}

Factoring, we have:

S=2\pi r (h+r)

Calculating the surface area of the can of fruit:

S=2\pi (30) (80+30)

S=2\pi (30) (110)

S=6600\pi

S\approx 20724 \text{ mm}^2
