Answer:
There are 1849 tiles on the whole wall.
Step-by-step explanation:
If there are 85 tiles along the two diagonals, we can use the following rule:

So we have 43 tiles in the first diagonal and 85-43 = 42 in the second diagonal.
Now, as we have a square the side will have 43 tiles so the total area will be cover with:

Therefore, there are 1849 tiles on the whole wall.

The value of the expression when g = -2 is -1
<h3>How to simplify the expression</h3>
Given the expression;
(5+2g)exp5
(5+2g)^5
For g = -2
Let's substitute the value of g in the expression
= ( 5 + 2 ( -2) ) ^5
Expand the bracket
= ( 5 - 4) ^ 5
Find the difference
= (-1) ^5
= -1
Thus, the value of the expression when g = -2 is -1

Step-by-step explanation:
Answer:
3/8 cups.
Step-by-step explanation:
2 tablespoons of sugar = 1/16 * 2 = 1/8 cup of sugar.
1/2 cup = 4/8 cups.
So the extra sugar required = 4/8 - 1/8
= 3/8 cups.
For this case we must find 35% of 280.
Kerrie gets 10% and then 25%. So:
10% of 280:
280 ------------> 100%
x -----------------> 10%
Where "x" represents the amount given by 10% of 280.

Thus, 10% of 280 is 28.
Now, we find 25% of 280:
280 ------------> 100%
x -----------------> 25%
Where "x" represents the amount given by 25% of 280.

Thus, 25% of 280 is 70.
So we have that 35% of 280 is given by:

So, Kerrie's solution is correct.
