Janell has a 10 inch by 12 inch photograph. She wants to scan the photograph

Complete Question:

Janeel has a 10 inch by 12 inch photograph. She wants to scan the photograph, then reduce the results by the same amount in each dimension to post on her Web site. Janeel wants the area of the image to be one eight of the original photograph. Write an equation to represent the area of the reduced image. Find the dimensions of the reduced image.

Correct

A)

B) Dimensions are : Length = 10-x = 3 inch , Breadth = 12-x = 5 inch

Step-by-step explanation:

a. Write an equation to represent the area of the reduced image.

Let the reduced dimensions is by x , So the new dimensions are

According to question , Area of new image is :

⇒

⇒

⇒

So the equation will be :

⇒

b. Find the dimensions of the reduced image

Let's solve :  

⇒

⇒

⇒

By Quadratic formula :

⇒

⇒

⇒

⇒

x = 15 is rejected ! as 15 > 10 ! Side can't be negative

⇒

Therefore, Dimensions are : Length = 10-x = 3 inch , Breadth = 12-x = 5 inch

step-by-step explanation:

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.
