Answer: -66

<u>Step-by-step explanation:</u>

use PEMDAS.  Evaluate the parentheses, then multiplication, then addition.

-3[-3(-4 - 1) - (-3 - 4)]

           ↓           ↓

-3[-3(  -5  ) - (   -7   )]

       ↓          ↓

-3[   15     +    7      ]

               ↓

-3[           22          ]

  ↓

-66

Which equation represents a circle with a center at (-4, 9) and a diameter of 10 units?
blsea [12.9K]

Answer:

(x+4)^2 + (y-9)^2 = 25

Step-by-step explanation:

We can use the equation (x-h)^2 + (y-k)^2 = r^2

where (h,k) is the center and r is the radius

The center is at (-4,9) and the diameter is 10 which means the radius is 10/2 or 5

(x- -4)^2 + (y-9)^2 = 5^2

(x+4)^2 + (y-9)^2 = 25

HELP 20 POINTS!
Butoxors [25]
For the first blank where it asks for the perimeter, the perimeter is all the outside sides of a shape added up. So, 6 + 1 + 2 + 4 + 4 + 5 = 22.

For the second blank, you just multiply the entire perimeter by 5, so, 22 times 5=110.

For the third blank, it is basically the same as the previous question. The answer is 5.

For the fourth blank, it is the same perimeter as the first blank, but instead of centimeters, it is in k. So, 22k.

Hope this helped! :)
