The sum of p and q means (p+q). The difference of p and q means (p-q).
The sum of q and 8 can be represented as q + 8. This is a simple algebraic expression where q is a variable representing an unknown value. Adding 8 to q means combining the value of q with 8 to get the sum.
It is: 4*(q+p)
Yes, irrational. Let p = root 2 and q = root 3. Then (q - p)2 = 5 - 2root6, which is irrational because it is the sum of an integer (5) and an irrational (2root6), and so q - p (which is root3 - root2) is irrational.
21-q
the sum of q plus 5!
The sum of p and q means (p+q). The difference of p and q means (p-q).
q+8
The sum of q and 8 can be represented as q + 8. This is a simple algebraic expression where q is a variable representing an unknown value. Adding 8 to q means combining the value of q with 8 to get the sum.
1+q
q - p
The expression is simply: 9+q
It is: 4*(q+p)
Get your book open and work out the problem. You need to do this.
Yes, irrational. Let p = root 2 and q = root 3. Then (q - p)2 = 5 - 2root6, which is irrational because it is the sum of an integer (5) and an irrational (2root6), and so q - p (which is root3 - root2) is irrational.
21-q
I think so.Sum = m + q
