The value of x is -3.5
Because dividing both sides by -2.4 is going to get you a value of -3.5. And a negative divided by a negative is a positive. :D
There are two different ways we can read your question.
Each way has a different answer.
Here it is both ways:
Way #1: (12 + 4n) / 3 = 8
Multiply each side by 3 : 12 + 4n = 24
Subtract 12 from each side: 4n = 12
Divide each side by 4: n = 3 .
====================================
Way #2: 12 + 4n/3 = 8
Subtract 12 from each side: 4n/3 = -4
Multiply each side by 3: 4n = -12
Divide each side by 4: n = - 3
The side of the edge of the cube is 7. 07cm
<h3>How to determine the length</h3>
Given that a diagonal of a cube measures the square root of 150 cm and the diagonal of a face measures 10 cm.
Let's find the edge of the face
Note that the face of the cube is in the shape of square .
The diagonal of the face is 10 cm.
The formula for diagonal of square =
a is the side of the square face
We have that,
Make 'a' subject of formula
a =
Find the surd of the equation, we have
a = ×
a =
a =
a =
Thus, the side of the edge of the cube is 7. 07cm

Step-by-step explanation:
That is the simplest it will go.
Answer:
145°
Step-by-step explanation:
< 6 + <2 = 180° {being linear pair }
70° + < 2 = 180°
< 2 = 180° - 70°
< 2 = 110°
Now
< 4 = < 1 + < 2 (exterior angle of a triangle is equal to the sum of two opposite interior angles)
<4 = 35° + 110°
= 145°
Hope it will help :)
