Write a polynomial expression, in simplified form, that represents the AREA of the blanket and use the expression to evaluate th
pochemuha

Answer:

Polynomial expression that represents the area of blanket:

A(x)=(6x^2+5x-21)cm^2

If x=2: A(2)=13cm^2  

Step-by-step explanation:

The area of the rectangle can be calculated with the formula:

A=lw

Being l the lenght of the rectangle and w the width of the rectangle.

In this case, the lenght and the width are represented with:

l=(3x+7)cm

w=(2x-3)cm

Substitute them into  A=lw:

 A(x)=(3x+7)(2x-3)

Then:

Use Distributive property (Remember the Product of powers property: b^a*b^c=b^{(a+c)} ):

A(x)=(3x+7)(2x-3)\\A(x)=6x^2-9x+14x-21

Add like terms:

A(x)=(6x^2+5x-21)cm^2 (Simplied form)

Evaluate x=2:

A(2)=(6(2)^2+5(2)-21)cm^2\\A(2)=(6(4)+10-21)cm^2\\A(2)=(24-11)cm^2\\A(2)=13cm^2

Anit [1.1K]

The hour all animals get fed at the same time if Frankie starts at 6:00 Am is 6:00 pm

<h3>Common multiple</h3><h3 />
  • Hamster 4oz of food = 6 hours
  • Guinea pigs 12oz of food = 12 hours
  • Land tortoise 24oz of food = 24 hours

Find the lowest common multiple

  • 6 hours = 6, 12, 18, 24
  • 12 hours = 12, 34, 36
  • 24 hours = 24, 48, 72

The lowest common multiple of 6, 12 and 24 is 12

if Frankie starts at 6:00 Am?

6:00 am + 12 hours

= 6:00 pm

Therefore, the hour all animals get fed at the same time if Frankie starts at 6:00 Am is 6:00 pm
