Step-by-step explanation:

Given

(w² - w + 1) + (w³ - 2w² + 99)

Now opening the bracket we get

w² - w + 1 + w³ - 2w² + 99

Re arranging,

w³- 2w²+w²- w+ 1+ 99

w³- w²- w+100

Thus the answer is  w³- w²- w+100

Answer:

w³ - w² - w + 100

Step-by-step explanation:

The sum of (w² - w + 1) and (w³ - 2w² + 99) is:

(w² - w + 1) + (w³ - 2w² + 99)

= w² - w + 1 + w³ - 2w² + 99

= w² - 2w² - w + w³ + 99 + 1

= -w² - w + w³ + 100

= w³ - w² - w + 100

Thus, (w² - w + 1) + (w³ - 2w² + 99) = w³ - w² - w + 100.

Find the midpoint of the line segment shown below.
balu736 [363]

Answer:

x²-6x+y²-4y=-4

Step-by-step explanation:

We know the circle equation stands like this:

(x-a)² + (y-b)² = R²

and (a,b) is center

and R stands for Radius

so in this case:

center = (3,2)

R = 3

So

(x-3)² + (y-2)² = 9

x²-6x+9 + y²-4y+4=9

x²-6x+y²-4y=-4
