Perimeter of the rectangle = 6 x +20

Perimeter of the rectangle = 0 x² + 6 x + 20

Step-by-step explanation:

Step(i):-

Given that the length of the rectangle = 2x +3

Given that the width of the rectangle = x +7

Perimeter of the rectangle = 2(length + width)

Step(ii):-

Perimeter of the rectangle = 2(length + width)

= 2(2 x +3 + x+7)

= 4x +6+2x+14

= 6 x +20

Final answer:-

Perimeter of the rectangle = 6 x +20

Perimeter of the rectangle = o x² + 6 x + 20

Adriel answered 54 questions correctly on his multiple choice history final and earned a grade of 45%. How many total questions were on the final exam?

Step-by-step explanation:

It is given that:

Number of questions answered = 54

Grade percent = 45%

Let,

x be the total number of questions

45% of x = 54

[tex]\frac{45}{100}x=54\\0.45x = 54[/tex]

Dividing both sides by 0.45

[tex]\frac{0.45x}{0.45}=\frac{54}{0.45}\\x=120[/tex]
