-26
This because 4x+132 =28
I dont know how your answer is negative though
9. √105 is irrational (105 is not the square of an integer) Its value is near +10.
-4 is an integer (and rational)
4/3 is a rational number
Smallest to largest, these are -4, 4/3, √105.
10. The nearest square less than 14 is 9 = 3×3. The nearest square greater than 14 is 16 = 4×4. 14 is closer to 16 than to 9, so we expect 4 to be the integer closest to its square root. (√14 ≈ 3.74, closer to 4 than to 3.)
11. The numbers are in the same order; only the location of parentheses has changed. The property that lets you do that with addition is the associative property.
Answer:
(4, - 1)
(-1, 6)
Step-by-step explanation:
Given the expression :
3x+y<14
Test the opprions to find out the true statement.
(7, - 7)
3(7) + (-7) < 14
21 - 7 < 14
15 < 14 (not true)
(-1, 6)
3(-1) + 6 < 14
3 + 6 < 14
9 < 14 ( true)
(3, 6)
3(3) + 6 < 14
9 + 6 < 14 ( not true)
(4, - 1)
3(4) - 1 < 14
12 - 1 < 14 ( true)
(6,0)
3(6) + 0 < 14
18 < 14 ( not true)
Answer:
Step-by-step explanation:
21 has no 2 in it's prime factorization. So it can never end in 0, 2 , 4 , 6 , 8.
OR
Odd number raise to any number is always odd, Which does not include 2, 4, 6 , 8.
So 
does not end with 0, 2, 4 , 6 , 8.
