A manufacturer makes rectangular blankets in several styles and sizes. The outline of a popular blanket in size A is shown below
nikdorinn [45]

Answer:

(10x + 8) is the polynomial expression for the perimeter of the blanket.

Step-by-step explanation:

The height and width of the rectangular blanket are (2x - 3) cm and (3x + 7) cm respectively.

Now, the perimeter of a rectangle having height h and width w is given by  

P = 2h + 2w

⇒ P = 2(2x - 3) + 2(3x + 7)

⇒ P = 4x - 6 + 6x + 14

⇒ P = 10x + 8.

So, this is the polynomial expression for the perimeter of the blanket. (Answer)

Hi, to answer this question, first, we have to calculate the number of years since 1990(x).

1997-1990 = 7 years

Now, we simply substitute x=7 (years) in the equation given

y=11x+12

y=11(7)+12

y=77+12

y = 89 retail stores

There were 89 retail stores in 1997.

A triangle has side lengths of 10,11, and 15. What type of triangle is it ?
Andreas93 [3]

Answer:

Obtuse

Step-by-step explanation:

square the 2 smaller side lengths.  10^2+11^2= 221.  If you square the longer side length, you get 225.  15^=225.  

An acute triangle is when the 2 smaller side lengths are greater

A right triangle is when the 2 smaller side lengths are equal

An obtuse triangle is when the 2 smaller side lengths are less.

221 is less than 225, making it obtuse.
