Answer:
1/5
Step-by-step explanation:
(5^7*5^5)/5^13 (when multiplying numbers with the same base, add the exponents)
= (5^12)/5^13 (when dividing exponents with the same base, subtract the exponents)
= 1/5^1 (anything to the first power is itself)
= 1/5
The first step for solving this expression is to distribute
through the first set of parenthesis.
× (x - 9)
Now use the FOIL method to multiply each term in the first parenthesis by each term in the second parenthesis. This will look like the following:
x × x -
x × 9 -
x -
× (-9)
Remember that multiplying two negatives together equals a positive,, so the expression changes to:
x × x -
x × 9 -
x +
× 9
Calculate the product of all of the sets of multiplication to make the expression become:
x² -
x -
x +
Lastly,, calculate the difference of -
x -
x to find your final answer.
x² -
x +

SU would be the hypotenuse so you can use Pythagorean Theorem to solve this problem.
42^2 + 56^2 = c^2
1764 + 3136 = c^2
4900 = c^2
70 = c
