Answer:
x² - 100
Step-by-step explanation:
Use the FOIL method. The FOIL method is the way in which you multiply the terms:
FOIL stands for First, Outside, Inside, Last. Multiply:
First:
x * x = x²
Outside:
x * 10 = 10x
Inside:
-10 * x = -10x
Last:
-10 * 10 = -100
Combine like terms:
x² + 10x - 10x - 100
x² + (10x - 10x) - 100
x² - 100
x² - 100 is your answer.

Answer:
Step-by-step explanation:
X no of questions student answers is binomial with n =40 and p =0.5
If approximated to normal, X is Normal with
mean = np = 20 and variance = npq = 10
P(X>N) >0.10
We use std normal distribution table to get z value first then convert to x value
So 
This is with continuity correction.
Hence without continuity correction this equals 7.2-0.5 = 6.7
x>6.7
n = 7
Based on the fact that the divers went scuba diving, the divers in the order from the least to the greatest based on the liters left in their oxygen tanks is Dante, Sofia, Alexis.
<h3>Which diver has the least amount of oxygen?</h3><h3 />
To find out which diver has the least oxygen, you need to convert the fractions to decimals.
Alexis has seventy one ninths which means that they have the most oxygen left as this is much more than the rest.
Sofia has seven and five eights which in decimal is;
= 7 + 5/8
= 7.625 liters
This means that Sofia has more oxygen than Dante who has only 7.5 liters.
The order is:
Dante, Sofia, Alexis.

Plugging x in, we have -x/3+2, which is -2/3+2=1.3 (with the 3 repeating).

5 is the answer. Any number that ends in 5 or 0 allows 5 to go into it.
