Answer:
The range of this set of numbers is 9
Step-by-step explanation:
The range is the greatest number subtracted by the lowest number
in this problem that is 21-12
Remember PEMDAS
Do parentheses, results in 25. So whats left is 87-25*(-3)+9
Then you multiply -25 by -3, answer is 75. 87+75+9
Add all of them up. 171
The answer is 171!
Answer:
x = 6
Step-by-step explanation:
The scale factor is
28/8 = 7/2
We take the ratio of the larger side over the smaller side
Using ratios we can find the sides
28 21
----- = ---------
8 x
Using cross products
28x = 21*8
28x =168
Divide each side by 28
28x/28 = 168/28
x =6
9(3+5) is equivalent because factoring a 9 out of both 27 and 45 leaves us with 9(3+5).
