What is the length of Line segment A J if Line segment A B is parallel to lines segment J K?

Reika [66]

Answer:

8.75 in.

Step-by-step explanation:

See attachment for the figure.

As you can see, ∆ HBA & ∆HKJ are similar,

HB/HA = HK/HJ

3/5.25 = 8/HJ

3HJ/5.25 = 8

3HJ = 42

HJ = 14 in.

AJ = 14 - 5.25

AJ = 8.75 in.

Therefore, the length of Line segment AJ is 8.75 in.

Length of a rectangle is 4x^2 + 12x and the area of the rectangle is 24x^4 + 72x^3, what is the width of the rectangle.

elena-14-01-66 [18.8K]

Width of rectangle is $6x^2$

Step-by-step explanation:

Length of rectangle = 4x^2+12x

Area of rectangle = 24x^4+72x^3

Width of rectangle = ?

Finding width of rectangle by using formula:

$Area = Length*Width$

$Width= \frac{Area}{Length}$

$Width=\frac{24x^4+72x^3}{4x^2+12x} \\Width=\frac{24x^3(x+3)}{4x(x+3)}\\Width=\frac{24x^3}{4x}\\Width=6x^2$

So, width of rectangle is $6x^2$
