Answer:

2x+8

Step-by-step explanation:

So when they say a number, they mean a unknown value.

We can use a variable as this unknown value. In this situration we can call it x.

This phase says "twice a number" or "twice x". This can be though of as 2x.

next it says this number is increased by 8. When they say increased they meanm added to.

So 8 is added to 2x. Or 2x + 8

So its the second answer, 2x+8.

Hope this helps!

Find the volume of a cylinder that has a radius of 7 and a height of 18.
ch4aika [34]

Answer:

V = 882pi units^3

or approximately

2769.48 units^3

Step-by-step explanation:

The column of a cylinder is given by

V = pi * r^2 * h

We know the radius is 7 and the height is 18

V = pi * 7^2 *18

V =pi *49 *18

V =882 pi

If we want an approximate answer, we can approximate pi by 3.14

V = 3.14 * 882

V =2769.48

Tan 37,4 = opposite/adjacent

tan 37,4 = x/12,8
• then multiply both sides by 12,8

12,8tan 37,4 = x
Therefore x = 9, 79 x 100
= 97, 86
= 100
( I guess that’s how you can round it to the nearest hundred, please correct me if I’m wrong)
