-7x + 5 = -9 -7x = -14 7x = 14 x = 2
3/7x + 5 = 87x(3/7x + 5) = 8(7x)3(7x/7x) + (7x)(5) = 8(7x)3 + 35x = 56x3 + 35x - 35x = 56x - 35x3 = 21x3/21 = 21x/211/7 = x
42 x 8 = (40 x 8) + (2 x 8) = 320 + 16 = 336
7x-6w = 1
4x-7x = -3
6x7=42 42x8=336 That is your answer, I hope I helped! ;)
7x^3. That is 7x cubed.... or 7x*7x*7x (where * means multiply). You should get 343x
1
(7x - 4)(7x + 4).
-7x + 6 + 7x - 2 = 4
None. 7x - 1 is not equal to 7x - 7.
-7x + 5 = -9 -7x = -14 7x = 14 x = 2
3/7x + 5 = 87x(3/7x + 5) = 8(7x)3(7x/7x) + (7x)(5) = 8(7x)3 + 35x = 56x3 + 35x - 35x = 56x - 35x3 = 21x3/21 = 21x/211/7 = x
42 x 8 = (40 x 8) + (2 x 8) = 320 + 16 = 336
The area of square is : 49.0
40 -7x = -16 -7x = -16 -40 -7x = -56 x = 8
(7x + 8)(7x - 9)
