Equation To write :2 {x+ ( x+5) }=30
Let's solve your equation step-by-step.
2(x+x+5)=30
Step 1: Simplify both sides of the equation.
2(x+x+5)=30
(2)(x)+(2)(x)+(2)(5)=30(Distribute)
2x+2x+10=30
(2x+2x)+(10)=30(Combine Like Terms)
4x+10=30
4x+10=30
Step 2: Subtract 10 from both sides.
4x+10−10=30−10
4x=20
Step 3: Divide both sides by 4.
4x

x=5
So... x+5=10.
Area =5x10=50 cm squared.
Answer:
5
Step-by-step explanation:
Okay, so P = perimeter, and the problem says P = 30
Let's call x the width, and y is the length.
In the perimeter formula, 2X + 2Y = P
so 2X + 2Y = 30
The problem also tells us that that x = y+5, so now let's do some substituting and replace X with Y+5
2(y+5) + 2Y = 30
2y+10 +2Y = 30
4y+10=30
-10. -10
4y=20
Y=5
