Answer:

D. 25p² - 1

Step-by-step explanation:

Each side length of a square = 5p

Length of rectangle = 5p + 1

Width of the rectangle = 5p - 1

Area of rectangle = Length × Width

Area of rectangle = (5p + 1)(5p - 1)

= 5p(5p - 1) +1(5p - 1) (distributive property)

= 25p² - 5p + 5p - 1

Area = 25p² - 1

Find the value of x in 19 and 20 so that f(x)=7​
mafiozo [28]

Answer:

Part 19) x=5

Part 20) x=-3

Step-by-step explanation:

Problem 19) Find the value of x so that f(x)=7

step 1

Find the intersection point of the given line in the graph with the line y=7

The intersection point is (5,7)

see the attached figure

therefore

The x-coordinate of the intersection point is the value of x when f(x)=7

x=5

f(5)=7

Problem 20) Find the value of x so that f(x)=7

step 1

Find the intersection point of the given line in the graph with the line y=7

The intersection point is (-3,7)

see the attached figure

therefore

The x-coordinate of the intersection point is the value of x when f(x)=7

x=-3

f(-3)=7
