a rectangle has an area of 102 cm2. the length of the rectangle is 17 cm. what is the perimeter of the rectangle?

Kruka [31]

Area = length *width

102 = 17*w

w = 102/17 = 6

l=17
w=6

perimeter = 2l +2w
p = 2(l+w)
p=2*23

p = 46 cm

Each side of a square is increasing at a rate of 4 cm/s. at what rate is the area of the square increasing when the area of the

Iteru [2.4K]

Confusing question but I would get 0, as if you have 4cm, that squared = 16cm^2. Therefore if it were increasing anymore, then you would not be able to get a value of 16.

Rewrite each expression as a polynomial in standard form: (2x^2 − x^3 − 9x +1) − (x^3 +7x − 3x^2 +1)

Vitek1552 [10]

Answer:

Polynomial in standard form will be $-2x^3+5x^2-16x$

Step-by-step explanation:

We have given polynomial $2x^2-x^3-9x+1-(x^3+7x-3x^2+1)$

We have to write this polynomial in standard form

For writing in standard form we have to first subtract the polynomial and then rearrange the order

So $2x^2-x^3-9x+1-(x^3+7x-3x^2+1)=2x^2-x^3-9x+1-x^3-7x+3x^2-1=-2x^3+5x^2-16x$

So polynomial in standard form will be $-2x^3+5x^2-16x$
