Answer:

y ≈ 2.262

Step-by-step explanation:

Using the rule of logarithms

log $x^{n}$ = nlogx

Given

$3^{y}$ = 12 ( take log of both sides )

log $3^{y}$ = log12 , then

ylog3 = log12 ( divide both sides by log3 )

y = $\frac{log12}{log3}$ ≈ 2.262 ( to 3 dec. places )

Answer:

Um I think its, To find the width, multiply the length that you have been given by 2, and subtract the result from the perimeter. You now have the total length for the remaining 2 sides. This number divided by 2 is the width.

What does parallelogram mean in a nutshell?

A parallelogram is a geometric shape with parallel sides that exists in two dimensions.
The pair of parallel sides in this sort of polygon with four sides, also known as a quadrilateral, are of equal length.
In a parallelogram, the sum of the adjacent angles is 180 degrees.

Perimeter of ∥gm = - 40 cm

2(PQ+ PS) = - 40

2 ( PQ + 7 ) = 40

PQ + 7 = 20

PQ = 20 - 7

PQ = 13 cm
