Answer:
-25
Step-by-step explanation:
formula for areas of rectangles= width x height
width=x-5
height=x+5
(x-5)(x+5)= -5x+5x-25
since the 5x's cancel out each other
=-25 will be the answer
Answer:
28/165
Step-by-step explanation:
You always use the order of operations, and the order of operations says to solve parentheses first, so you would solve 5/9 - 1/6, and get 7/18.
You would do exponents next, if there were any, but there is not, so you move on to the next operation(s).
The next operations are multiplication and division. From left to right, multiplication is first, so you solve 8/11 x 7/18 and get 28/99. Then, there is a division problem to solve. The problem is 28/99 ÷ 15/9. If you solve that correctly, you will get the answer 28/165.
The next step would be to simplify 28/165, but it cannot be simplified, so you are left with the answer 28/165.
The measurment you would use to find volume of a cup is the metric system
For the answer to the question above, I think since there are only two numbers in the given sequence that are even or greater than 78. I think the probability would be <u><em>0.4 </em></u>
I hope this helps you somehow. Have a nice day!
