Hi!
Let's just take this part by part.
The sum of seven is the first part written. You can deduce from that, that it's 7 + something.
The next part is the quotient of a number x and 8. A quotient is the result of something being divided, so we can figure out that it's x / 8.
Putting it all together, you get the expression as 7 + x / 8.
Hope this helped!
Answer:
40
Step-by-step explanation:
Given problem:
x² - y²
x+ y = 10
x - y = 4
Solution:
Using the concept of differences of two squares;
x² - y² = (x + y)(x - y)
So;
x² - y² = 10 x 4 = 40
Answer: -8
Step-by-step explanation:
If we add 5 to -8, that will be -3. Then if we multiply -3 with -2, it equals 6 because when two negatives multiply with one another the answer will be positive.
So in conclusion, the number is -8.
