Jovana was trying to find a formula for that perimeter with one side 8 yards longer than the other side using the area. In which step did she make a mistake? Step 1: a=x(x+8)=256 Step 2: 256/x=x+8 Step 3: p=2[x+(x+8)] Step 4: 1/2p=x=(x+8) Step 5: 1/2p= x+256/x Step 6: 1/2p-x=256/x Step 7: x[1/2p-1]=256 Explain her mistake. What is the correct formula?

step-by-step explanation:

whats the

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

don't report but were is the digram
