Answer:
n = 8.
Step-by-step explanation:
n^2 × constant nunber = W.
5^2 × constant number = 175. So the constant number is 7.
When W = 448, n^2 = W/7, n^2 = 64.
Thus, n = 8.
The perfect squares on either side of 21 are 16 and 25 of which the roots are:
4 and 5
Answer:
DH
Step-by-step explanation:
Answer:
A) 2(9x - 2)
Step-by-step explanation:
The greatest common factor of 18x and -4 is 2.
B is wrong because 18 is not the greatest common factor of both, since 4 cannot be divided by 18 and result in a whole number.
C is wrong because 18x cannot be divided by 4 to produce a whole number.
D is wrong because it restates the problem in a different way, therefore not factoring it completely. 1 is a common factor of both, but not the greatest.
