Answer:
3, 14, and sqrt205.
2,9, and sqrt85.
Step-by-step explanation:
Check if they fit the Pythagoras theorem c^2 = a^2 + b^2:
3^2 = 9 , 14^2 = 196.
9 + 196 = 205 which is the square of sqrt205.
So this is a right angled triangle.
6^2 + 11^2 = 36 + 121
= 157 Not right-angled.
19^2 + 180^2 = 32761 Not right-angled.
3^2 + 19^2 = 370 Not right-angled.
2^2 + 9^2 = 85, So this is right angled..
Answer: 456 chairs
Step-by-step explanation:
If there are 6 round tables with 7 chairs each you would multiply 7, 6 times (7 x 6) = 42
If there are 23 rectangular tables with 18 chairs each you would multiply 18, 23 times. ( 18 x 23) = 414
Then you add up all the chairs, 456 chairs total.
Answer:
ratio of regular to diet soda = 16/9
Step-by-step explanation:
Jessica brought a cooler to the family picnic filled with 32 cans of regular soda and 18 cans of diet soda. This means
Number of cans of regular soda = 32
Number of cans of diet soda = 18
Total number of soda brought to the family picnic = number of cans of regular soda + number of cans of diet soda
= 32 + 18= 50
the ratio of regular soda cans to diet cans in the cooler= 32/18
Divide numerator and demo minator by 2, we have 16/9.
The fraction cannot be reduced further. So ration of regular to diet soda = 16/9

Answer:
72y2-45
Step-by-step explanation:
9y2 + 9(7y2 - 5)
you multiply the 9 by the stuff in the parentheses
