2|x + 5| = 16

|x + 5| = 16 ÷ 2

|x + 5| = 8

x + 5 = 8   (a)

x = 3

-(x + 5) = 8   (b)

-x - 5 = 8

-x = 13

x = -13

x = 3, -13

The first step would be to divide both sides by 2...because u want to get the absolute value on one side, and everything else on the other side

2 | x + 5 | = 16...divide both sides by 2
| x + 5 | = 16/2
| x + 5 | = 8

u would then solve x + 5 = 8 and x + 5 = -8 for ur answers

The radius of a well is 1.4m and its depth 35 m is half-filled with water. find the volume of water inside the drum.
Rzqust [24]

Answer:

≈ 108 m³

Step-by-step explanation:

You're searching for the volume of a cylinder. The formula needed to find it is V=πr²h.

In this case, the radius r is 1.4m and the height h is 35/2=17.5m, as it is only half filled.

Now when inserting values, you get: V=π*1.4²*17.5 which is 107.757 m³
