3 squared = 9 9 - 2 x 1 = 9 - 2 = 7
2xy*9 if x=3 and y = 2 2(3)(2)*9 12*9 108 You substitute x and y for their equivalent (3 and 2) then simply multiply 2*x*y, then multiply the answer of that by 9.
To find the units digit of (29^{57}), we can focus on the units digit of the base, which is 9. The units digits of powers of 9 follow a pattern: (9^1 = 9), (9^2 = 81) (units digit 1), (9^3 = 729) (units digit 9), and (9^4 = 6561) (units digit 1). This pattern alternates between 9 and 1. Since (57) is odd, the units digit of (29^{57}) is the same as that of (9^{57}), which is (9). Thus, the units digit of (29^{57}) is (9).
2/3 x 9/19 = (2 x 9)/(3 x 19) = 18/57 = 6/19.
4' 9" = 12*4 + 9 = 48 + 9 = 57" 6' 2" = 12*6 + 2 = 72 + 2 = 74" So Rosalind is 57 - 74 = - 17 inches taller.
Replace the y with a 3. 16 x 3 + 9 = 57
48 + 9 = 57/2 = 28.5

9 - 4x = 57 9 - 9 - 4x = 57 - 9 -4x = 48 -4x/-4 = 48/-4 x = -12 Always double check your answer. 9 - 4x = 57 9 - 4(-12) = 57 9 + 48 = 57 57 = 57 So 9 - 4x = 57 when x = -12

The factors of 57 are 1, 3, 19, and 57The factors of 18 are 1, 2, 3, 6, 9, and 18
evaluate means the same thing as solve in most math terms so9^2= 81
