The perimeter of a parallelogram is 56 meters the width of the parallelogram is 8 meters less than its length find the length of

Dimas [21]

Answer:

length = 18 mt

Width = 10 mt

Step-by-step explanation:

Let the length of the field be x

width of the field be y

Hence

P=2(x+y)

P=56 (given)

56=2(x+y)

Dividing both sides by 2 we get

x+y=28 ---(A)

Also given that width of the parallelogram is 8 meters less than its length

Hence

y=x-8

or x-y=8 ---(B)

Adding A and B

2x=36

x=18

y=x-8

y=18-8=10

Hence length = 18 mt

Width = 10 mt

Can someone help my find the fraction and explain how you got it please please

Harrizon [31]

The fraction is 1/3. on the input side, it’s going up by one, (6,7,8 etc) and on the output side it’s going up by 3. (18+3=21). if u were to double check 6/18 reduces to 1/3! so the answer is 1/3

What is the maximum value of P = 4x + 2y, given the constraints on x and y listed below?

Aliun [14]

What are the constraints?

When you graph the constraints the four points you can use are (0,0), (10,0), (0,2), and (6,2).

(10,0) is the point that gives you the maximum value which is 40.

Help plzzz!! Marking most Brainly;)

Answer:

D it

Step-by-step explanation:

We have two equations, A quadratic and a linear equation.

The domain of a linear equation and quadratic equation is all real numbers but since it dealing with time we must make sure the roots or x-intercepts is positive.

Looking at the quadratic equation, we can use the discramnt formula to see if all roots are positve.

$b {}^{2} - 4ac$

${ - 6}^{2} - 4(1)(8.75)$

$36 - 35 = 1$

The discramnt is greater than zero so there is two distinct real roots. So let check if they are positve

If you graph the equation, it intercepts at two positve roots so it is D
