21x21 equals 7x7x9
11*7 dawgs
24 x7 =168 hours
If you mean n times 7 equals 56... Then the value of n is 8 !
2x7 = 14 x7 = 7 3x7 = 3*7 = 21
There are 18 feet times 7 feet equals 126 square feet
Depends on where the parentheses are. X(7-4) + X7 + 4 = 10X + 4 X(7-4) + X(7+4) = 14X
There is a formula for the "difference of squares." In this case, the answer is (x7 - 7)(x7 + 7)
7 + 7 + 7 + 7 = 28
(x4 * x10)/(x7)x14/x714 - 7 = 7= x7===
(3/7+3)x7
x7 is the same as 7x. However, x^7 is significantly different from 7x
