Add them all up and if they do not equal what is on the other side of the equal sign, then it is incorrect. If it does add up to what is on the other side of the equal sign, then it is correct.
Answer:
5 negative tiles and 5 negative tiles
Step-by-step explanation:
When multiplying a positive number by a negative number, the product is always negative.
This can be visualized using integer tiles:
THe first thing we need to do is find the hypotenuse. From the tangent we know that the legs of the right triangle are 3 and 4. So this 2/3 of a special right triangle (3-4-5). Thus the hypotenuse is 5. The sin is defined as

. We know the opposite is 4 and hypotenuse is 5. Thus the sin is
Assuming the loan is as described, seven-year loan, which means that Kyle does not repay a cent before seven years.
This is a compound interest problem where n=7 years, interest rate i=0.05, and present value P=8000.
At the end of seven years, Kyle will have to pay
Future value = F = P(1+i)^n = 8000(1.05)^7 = 11256.80 (to the nearest cent)
