Find the length of a rectangle lot with a perimeter of 66 feet if the length is 3 times more than 4 times the width.
ValentinkaMS [17]

Answer:

27 feet

Step-by-step explanation:

We are told in the question that a lot is rectangular in shape

The perimeter of a rectangle

= 2(L + W)

= 2L + 2W

Where

L = Length of the rectangle

W = Width of the rectangle

From the question,

P = 66 feet

The length is 3 times more than 4 times the width

L = 3 + (4 × W)

= 3+ (4W) = 3 + 4W

Hence,

P = 2L + 2W

66 = 2(3 + 4W) + 2W

66 = 6 + 8W + 2W

Collect like terms

66 - 6 = 8W + 2W

60 = 10 W

W = 60/10

W = 6

The Width of the rectangular lot = 6 feet

To find the length

Perimeter = 2L + 2W

Perimeter - 2W = 2L

L = Perimeter - 2W/2

L = 66 - 2(6)/2

L = 66 - 12/2

L = 54/2

L = 27

Therefore the Length of the rectangular lot = 27 feet

Re-write the quadratic function below in Standard Form<br> y=-3 (x - 2)² – 7
pav-90 [236]

Answer:

y=-3x^2+12x-19

Step-by-step explanation:

we know that

The quadratic equation in standard form is equal to

y=ax^{2} +bx+c

we have

y=-3(x-2)^{2}-7

This is a quadratic equation in vertex form

Convert to standard form

y=-3(x^2-4x+4)-7

Apply distributive property

y=-3x^2+12x-12-7

Combine like terms

y=-3x^2+12x-19 ----> quadratic equation in standard form
