The GCF of 9 and 21 is 3.
4(21 + 4)
-19
As a quadratic expression it is: w^2 +10w +21
No because it contains an equal sign in it.
The expression 1000^(1/3) is equivalent.
It is: 3n-21+4n+8 = 7n-13 simplified
21
negative means opposite therefore -(-21) = 21 so your answer is 21
The expression cannot be evaluated because there are no operators between the terms. Also because nothing is known about p.
21 over 40 is irreducible as a fraction expression. 21 over 40 is 0.525 as a decimal expression.
6 + 3 + 21 + 63 + 21 = 114
