The perimeter of a rectangle is 40 cm. The length is 14 cm. Let x = width of the rectangle. Ravi says he can find the width usin

g the equation 2(x + 14) = 40. Fran says she can find the width using the equation 2x + 28 = 40. Answer the questions to solve the equations and to compare the steps and solutions. 1. Which of these is the most helpful first step for solving Ravi's equation, 2(x + 14) = 40? Circle the best answer. Add 14 to both sides Subtract 14 from both sides Divide both sides by 2 Multiply both sides by 2

Answer:

Divide both sides by 2

Step-by-step explanation:

We have the equation

2(x + 14) = 40

We divide both sides by 2

2(x + 14) = 40/2

x + 14 = 20

x = 20 - 14

x = 6

Therefore, the most helpful first step for solving Ravi's equation is: Divide both sides by 2

Choose the statement beloe that lists the sides in order from Least to Greatest.
kolezko [41]

Option A: SU, TU, ST is the right answer

Step-by-step explanation:

In a triangle

  • The largest side and the largest angle are opposite to each other
  • The shortest side and the shortest angle are opposite to each other.

So using the above axioms we can observe the triangle.

  1. The largest angle is m∠U = 80° so the side opposite to it is the largest i.e. ST is the largest
  2. The smallest angle is m∠T = 25° so the shortest side is SU
  3. The third side will be the middle side as the angle ∠S is greater than 25° and less than 80°

So the sides in order from least to greatest are: SU, TU, ST

Hence,

Option A: SU, TU, ST is the right answer
