Let width = x, then length = 3x - 2.
So we have area = width * length = x * (3x + 2)
A = 3x² + 2x

Now we need to find A(2) = 3 * 2² + 2 * 2 = 16ft²

(x÷5) + (x÷3) = 8/15<br><br><br> Help please!

$x\div5=\dfrac{x}{5},\ x\div3=\dfrac{x}{3}\\\\(x\div5)+(x\div3)=\dfrac{8}{15}\\\\\dfrac{x}{5}+\dfrac{x}{3}=\dfrac{8}{15}\ \ \ \ \ |\cdot15\\\\15\cdot\dfrac{x}{5}+15\cdot\dfrac{x}{3}=15\cdot\dfrac{8}{15}\\\\3\cdot\dfrac{x}{1}+5\cdot\dfrac{x}{1}=1\cdot\dfrac{8}{1}\\\\3x+5x=8\\\\8x=8\ \ \ \ |:8\\\\\boxed{x=1}$

What is 3x + x - 5 = 2(x-2) ?<br> Show each step

prohojiy [21]

Step 1: Distribute. On the right side, you should get =2x-4
Step 2: Add all common bases. You should get 4x-5 on the left side
Step 3: Add on each side. For example, add five to each side of the equation. Your equation should look like this; 4x= 2x+1
Step 4: Subtract each x number by 2x. Your equation should be; 2x=1
Step 5: Divide each side by two. Your answer should be x=1/2 or x=0.5
Hope this helped!
