Answer:

Step-by-step explanation:

Well.. First of all, the question says that we are working with a rectangle..

So, the rectangle has a length and width. I'll call them L and w.

Look at this phrase: " length that is one foot less than twice its width"

it means, in a algebraic language: L = 2w - 1

Let's analysis the next phrase: "it the area of the rectangle is 91 square feet"

So, A = 91 ft²

But you have to remember that the rectangle area is a product of L and w.

L x w = 91

They are the following equations that you could be used to solve the system of equations.

Now, you have a system of equations and I suggest you to solve it using the substituition method.

L = 2w - 1

L x w = 91

BRAINEST IF YOU GET THSI RIGHT
Scorpion4ik [409]
<h3>Solution :</h3>

\sf \dfrac{6x+4}{3} = \dfrac{5x-5}{8}

By cross multiply, we get

\sf : \implies (6x+4) \times 8 = (5x-5) \times 3

\sf : \implies 48x+32 = 15x-15

\sf : \implies 48x+32 - 15x + 15= 0

\sf : \implies 33x + 47 = 0

\sf : \implies 33x = -47

\sf : \implies x = \dfrac{- 47}{33}

Therefore, answer is \sf x = \dfrac{- 47}{33}

Find the nth term of this sequence, 3, 6, 9, 12
miss Akunina [59]

Answer:

\large\boxed{\sf n^{th} \ term =3n}}

Step-by-step explanation:

Find common difference from subtracting any term in the sequence with the previous term.

\large{\sf 6-3}=3

Apply nth term formula.

\large{\sf a_n=a_1+(n-1)d

\large{\sf d=3 \ \ a_1=3}

\large{\sf a_n=3+(n-1)3

\large{\sf a_n=3+3n-3

\large{\sf a_n=3n}
