The area of a rectangle is 20 square inches. If the length is 4 inches less than 6 times the width, then find the dimensions of

Tpy6a [65]

Step-by-step explanation:

Let the width=x

Length =6x-4

As we know that in a rectangle

${\boxed{\sf Area=LB}}$

Substitute the values

$\hookrightarrow\sf x (6x-4)=20$

$\hookrightarrow\sf 6x^2-4x=20$

$\hookrightarrow\sf 6x^2-4x-20=0$

Here a=6, b=-4, c=-20.
use quadratic formula

$\hookrightarrow\sf x=\dfrac {1}{3}+\dfrac {1}{3}\sqrt {31} \quad or \quad \dfrac {1}{3}+\dfrac {-1}{3}\sqrt {31}$

What is the solution of the system of equations c + 4d = 8 and c = 4d - 6

Tema [17]

Rewrite the second equation in same form as the first So we have

c + 4d = 8

c - 4d = -6 Now add:-

2c + 0 = 2
2c = 2

c = 1

Now substitute c = 1 in the first equation:-

1 + 4d = 8
4d = 7

d = 7/4 = 1 3/4

Answer c = 1 and d = 1 3/4 Answer
