Answer:
The area is 15 cm^2.
Step-by-step explanation:
Step 1: Start with the given formula.
Step 2: Then replace l and w with the given measures.
Step 3: Then do the calculation.
Step 1: A = lw
Step 2: A = (3 cm) * (5 cm)
Step 3: A = 15 cm^2
Answer: The area is 15 cm^2.
Answer:
Step-by-step explanation:
? = 1/2(230)
A 115°
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.
