Answer: She had added the Denominator, instead of finding the LCM.

Explanation: She should've multiplied them by a common number to equal a common Product, and replace the Denominator with the Product. (The correct denominator is 20, because 4 x 5 = 20, and 5 x 4= 20)

Evaluate the following equations
DochEvi [55]

Step-by-step explanation:

A....

Solution ,

=  \frac{h - 3}{3}  = 3h \\

= h - 3 = 9h

= h - 3 - 9h = 0

= h - 9h = 3

=  - 8h = 3

Change the sign of both side

= 8h =  - 3

= h =  -  \frac{3}{8 }  \\

B....

Solution,

=  \frac{t}{2}  =  \frac{t + 1}{5}  \\

Multiply the both side by the least common multiple to eliminate the fraction...

= 5t = 2t + 2

= 5t - 2t = 2

= 3t = 2

= t =  \frac{2}{3}  \\

A rectangle has an area of 45x2 − 42x − 48 and a width of 5x − 8. what is the length of the rectangle? to find the length of the
kondaur [170]

If the area and width of the rectangle are 45x² − 42x − 48 and (5x − 8) then the length of the rectangle will be (3x + 2).

<h3>What is a rectangle?</h3>

It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In a rectangle, opposite sides are parallel and equal and each angle is 90 degrees. And its diagonals are also equal and intersect at the mid-point.

A rectangle has an area of 45x² − 42x − 48 and a width of 5x − 8.

Then the length of the rectangle will be

area = length × width

Then we have

Area = 45x² − 42x − 48

Then the factor of the polynomial will be

Area = (5x − 8)(3x + 2)

Then the length of the rectangle will be (3x + 2).

More about the rectangle link is given below.
