Answer:
0
Step-by-step explanation:
5x+10-4=13-7x-7
5x+6=6-7x
5x+0= -7x
0=-12x
Divide and u get x=0
In this case just change the variables by the numbers. (1,5)
x=1 y=5
1^2 + 5^2 = 26
1+25=26
26=26 *this one is the answer...
TRUE
x2 + y2 = 16
1^2 + 5^2=16
1+25=16
26=16
False
x2 + y2 = 13
1^2 + 5^2=13
1+25=13
26=13
False
x2 + y2 = 11
1^2 + 5^2=11
1+25=11
26=11
False
So we can say that the first one is the answer.
Answer:
b
Step-by-step explanation:
Given:
The two numbers are
![A=23\times 3\times 5](https://tex.z-dn.net/?f=A%3D23%5Ctimes%203%5Ctimes%205)
![B=22\times 3\times 52](https://tex.z-dn.net/?f=B%3D22%5Ctimes%203%5Ctimes%2052)
To find:
The highest common factor (HCF) of A and B
Solution:
We have,
...(i)
![B=22\times 3\times 52](https://tex.z-dn.net/?f=B%3D22%5Ctimes%203%5Ctimes%2052)
All the factors of A are prime but the factors of B are not prime. So, it can be written as
...(ii)
From (i) and (ii), it is clear that 3 is the only common factor of A and B. So,
![HCF(A,B) = 3](https://tex.z-dn.net/?f=HCF%28A%2CB%29%20%3D%203)
Therefore, the highest common factor (HCF) of A and B is 3.
