Answer:
i know the answer for question 8 & 9
8) Volume is the amount of space a 3D shape takes up.
A cubic cm block takes up 1 cubic cm. This is written as 1 cm³.
You can work out the volume of a shape by multiplying height × width × depth.
If the shape is made of cubic cm blocks, you can count the cubes to find the shape's volume.
9) The face or surface of a solid on its sides. That is, any face or surface that is not a base. See also. Lateral surface area, prism, pyramid, cone, cylinder.

I like to think of these like this.
What was the amount of the discount? 300 - 234 = $66 dollars.
66 is to 300 as ? is to 100?
This is how that question looks in an equation:
66/300 = x/100 Solve for x by cross multipying.
66 x 100 = 300 x
660 = 300 x
x = 22
The discount amount on the tablet is 22% off the regular price.
Check it!
300 x .22 = $66 dollars off. 300 - 234 = $66 off.
Yes! It checks.
The two numbers in question obtained by creating a system of equations are 56 and 36
Let the two numbers be : a and b
From (2):
Substitute (3) into (1)
a + b = 92
20 + b + b = 92
20 + 2b = 92
2b = 92 - 20
2b = 72
b = 72/2
b = 36
From (3) :
a = 20 + 36
a = 56
Therefore, the two numbers are 56 and 36

(4a^4b)^2
= 4^2a^8b^2
= 16a^8b^2
