That simply means that you divide w by 8. This can be written as w/8, or as (1/8)w.
Let w equal the width and l equal the length of the rectangle. This means that 2w+2l=135 and since the rectangle has a scale factor of 8:1, that w/l=8. We now have a system of equations. Solve the second equation for w and find that w=8l. Substitute this into the first equation and find that 2(8l)+2l=135, which simplifies to 18l=135. Solve for l to get l=7.5 units. Plug this into either of the original equations to find that w=60 units. The dimensions of the rectangle are 60 by 7.5 units.
It could be either, depending on what x equals. If x = 9, 8 will solve the first one. If x = 1, 8 will solve the second one.
w^2 +/- 28w - 1 is an expression, not an equation. Expressions do not have solutions.
8*w*w*w*w = 8w^4

1/2 = 6/8 6/8 - 3/8 = 3/8
Solve one of the formulas for A, then substitute that into the other formula to solve for B, then substitute the solution for B into one of the formulas to solve for A. Here is how: Givens: A+B=8 A-B=9 So: If A+B=8 then A=8-B Next, substitute this into the other formula... A-B=9 (8-B)-B=9 (-B) - B = 1 (-2B) = 1 B= (- 1/2) Next, substitute the solution for B into one of the formulas to solve for A.... A+B=8 A+ (-1/2) = 8 A = 8 and 1/2 So... B= (- 1/2) A = 8 and 1/2
w + 23w = 24w
1.61803.... == solve for w. thanks, sherri

l*w = 128 2(l+w)= 48 ie l+w = 24 Solve these two to give the solutions 8 and 16. Since normally l > w, the answer is length = 16 cm, width = 8 cm.
