Answer:

L = 12

W = 6

Step-by-step explanation:

W = 2L

A = L * W

A = 72

72 = L * 2L

72 = 3L

24 = L (you have to divide by 2)

L = 12

W = 6

\triangle RST \cong \triangle TUR  

Step-by-step explanation:

Given: RSTU is a parallelogram.

By definition of parallelogram, two pairs of opposite sides are congruent in length.

⇒TU \cong RS and TS \cong RU

In triangle RST and  triangle TUR

RS \cong TU  [Side]  

TS \cong RU  [Side]

RT \cong RT   [Common side]

SSS(Side-Side-Side) postulates states that if three sides of one triangle are congruent to three sides of other triangle, then the triangles are congruent.

then, by SSS postulates we have;

\triangle RST \cong \triangle TUR

What is the solution of the equation 3(4b – 2) = –6 + 12b?
kvv77 [185]

Answer:

infinite number of solutions

Step-by-step explanation:

3(4b - 2) = - 6 + 12b ← distribute parenthesis on left side by 3

12b - 6 = 12b - 6

The expressions on both sides are the same

This indicates the equation has an infinite number of solutions
