Answer:
1: 4 1/2 hrs. | 2: 16 | 3: yes
Step-by-step explanation:
1: 1.5 x 3 = 4.5 = 4 1/2
2: 24 ÷ 3 = 8 24 - 8 = 16
3: 16 x 5.5 = 88
hope this helps :)
Answer:
x^2+y^ 2+2x-4y-11=0
x^2 + 2x + ? +y^2 - 4y + $ = 11 + ? + $
x^2 + 2x + 1 + y^2 - 4y + 4 = 11 + 1 + 4
(x + 1)^2 + (y - 2)^2 = 16
(x - - 1)^2 + (y - 2)^2 = 4^2
Center (-1,2) and radius = 4 (see bold in line above)

Answer:
588
Step-by-step explanation:
In a factor tree, I mostly like to look from down to up so that I can track down the non-square number. In a square number, there must be two factors that are exactly the same as each other, and when multiplied gives that square number.
So based on the 5 × 5, 2 × 2, and 7 × 7, we can tell that 25, 4 and 49 are all square numbers. We move up one level. Since the factors of 196 are square numbers, 196 is also a square number since it consists of 2² × 7².
We move another step up. 588 consists of 3 and 196. We know that 196 is a square number, but 3 is a prime number, which means that 3 only has a factor of 3 and itself. Thus, 588 is not a perfect square number since there should be a double factor for 3.
