X + 2y = 11
2x + y = 31
x = 11 - 2y
2(11 - 2y) + y = 31
22 - 4y + y = 31
3y = - 9
y = - 3
x = 11 - 2(-3)
x = 11 + 6
x = 17
Answer:
C. 14xy - 6y²
Step-by-step explanation:
The distributive property will essentially result in the sum of the product of the "outside term" with each of the "inside terms".
Here, the "outside term" is 2y and the "inside terms" are 7x and -3y. So:
2y(7x - 3y) = 2y * 7x + 2y * (-3y) = 14xy - 6y²
The answer is C.
Answer:
Interquartile Range = 34
Range = 55
Step-by-step explanation:
Max - Min = Range
75 - 20 = 55
Quartile 3 - Quartile 1 = IQR
68 - 34 = 34
No its not. the square root of 15 is about 3.873. Thus, the square root of 15 is not an integer, and therefore 15 is not a square number.
