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

Answer:
x=-5/53
Step-by-step explanation:
1. Add similar elements: 4x+27x=31x
2. Multiply 13 times 2 to get 26
3. Once again add the similar elements: 31x+26x=57x
4. Expand!!: Originally (4x+1) take away the Parentheses!!
5. 57x+6=4x+1
6. Subtract 6 from both sides: 57x+6-6=4x+1-6
7. Simplify: 57x=4x-5
8. Subtract 4x from both sides: 57x-4x=4x-5-4x
9. Simplify: 53x=-5
10. Divide both sides by 53: 53x/53= -5/53
11. x= -5/53
Area =lw
=2x (8+1)
=2x (9)
=18x
therefore the area is 18x
Answer:
C
Step-by-step explanation:
30:14
Divide both sides by 2
= 15:7
