The new equation will be (x-1)² + (y-18)²=36
2) x²+y²+6x+12y=4
(x²+6x+?)-(?) + (y²+12y +??) -(??)=4
(x²+6x+9)-(9) + (y²+12y +36) -(36)=4
(x+3)² - 9 + (y+6)² - 36 = 4
(x+3)² +(y+6)² = 49
If you're looking for Sam's age, the equation is 2x+5=3x-1. When solved, you get 6. Sam is 6.
Nina used 2 cups. The correct answer is B. Use this formula;
lets assume y is the amount of ounces she used. Lets assume x is the amount of cups she used.
y = x(8)
Replace y with 16.
16 = x(8)
Divide by 8.
2 = x
Thus, 2 cups.
Answer:
19.5
Step-by-step explanation:
Circumference is radius multiplied by 2, then multiplied by pi.
3.1 × 2= 6.2
6.2 × π= 19.477 ≈ 19.5
π also equals 3.14
Answer:

Step-by-step explanation:
On each median the distance from the vertex to the centroid is twice the distance from the centroid to the midpoint, or
the distance from the centroid to the midpoint is one third of the median

LF = 2 × HL = 2 × 30 = 60
HF = HL + LF = 30 + 60 = 90

LJ = DL = × 24 = 12
DJ = DL + LJ = 24 + 12 = 36
