To do this, we simply need to check if the given sides of the shelf is right-angled.
So, we have:


To check for right-angle triangle, we make use of:

This gives:




This shows that the given sides of the shelf is a right-angled triangle.
Hence, it will fit the wall
Since were trying to solve for n, you have to isolate it so you would divide both sides by 10, and that will give you n = 4

Q10.
Let's find a conclusion having statements step by step.
a) If 3 cans of soup cost a total of $0.85, then 1 can of soup costs:

b) If I get n cans of soup the equation I need to use is multiply the previous equation by n:

The conclusion is: G. Multiplying n by the cost of 1 can.
Q11.
Let's find a conclusion having statements step by step.
a) The company charges $40 to hook a vehicle, so this is a constant variable. Then:
c = 40$
b) There is a second statement that states that for each mile the vehicle is towed the cost increases $1.70, so:
c = $40 + 1.70m
So, the answer is
B.
