exis [7]

Answer:

Option A P=26\ in

Step-by-step explanation:

we know that

The perimeter of the rectangle is equal to

P=2(L+W)

we have

L=10\ in

W=L-7 -----> equation A

substitute the value of L in the equation A

W=10-7=3\ in

Find the perimeter

P=2(10+3)=26\ in

the discriminant is:

D = (-1)^2 - 4*(-2)*6 = 49

We have a positive discriminant, which means that we have two real solutions.

<h3>How to find the discriminant?</h3>

For the general quadratic equation, the discriminant is:

a*x^2 + b*x + c = 0

The discriminant is:

D = b^2 - 4ac

In this case, the quadratic equation is:

6*x^2 - x - 2 = 0

Then we have:

a = 6, b = -1, c = -2

Replacing that in the discriminant equation:

D = (-1)^2 - 4*(-2)*6 = 49

We have a positive discriminant, which means that we have two real solutions.
