1 answer:

5 0

Answer: Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area

What is the x in this equation <br><br> 14x−8=4

Aleksandr-060686 [28]

Answer:

x = 6 / 7

Step-by-step explanation:

Let's solve your equation step-by-step.

14 x − 8 = 4

Step 1: Add 8 to both sides.

14x − 8 + 8 = 4 + 8

14x = 12

Step 2: Divide both sides by 14.

14 x / 14 = 12 / 14

x = 6 / 7

Find the value of the variable and yz if y is between x and z Xy=6b yz=8b Xz=175

Anika [276]

The value of b is 12.5 and the value of YZ is 100

<h3>How to determine the variable and yz?</h3>

The given parameters are:

XY = 6b

YZ = 8b

XZ = 175

This means that

XZ = XY + YZ

So, we have:

6b + 8b = 175

Evaluate the sum

14b = 175

Divide by 14

b = 12.5

Substitute b = 12.5 in YZ = 8b

YZ = 8 * 12.5

Evaluate

YZ = 100

Hence, the value of b is 12.5 and the value of YZ is 100
