The formula is (x-h)^2+(y-k)^2=r^2
so, using this, and knowing that h is -3 and k is -5 and r is 4, we get
(x--3)^2+(y--5)^2=(4)^2, which equals
(X+3)^2+(y+5)^2=16

Answer:
174 square feet
Step-by-step explanation:
18*9= 162
6*4=24/2=12
162+12=174
The answer is 10x+9y+6 if your trying to combine all like terms.
Answer:
Step-by-step explanation:
1). 3x + 10
3(2) + 10
= 16
2). 14 - 2y
14 - 2(-3)
= 20
3). 7x - 5y
7(2) - 5(-3)
= 29
4). 5x + 7
5(2) + 7
= 17
5). 2x + 3y
2(2) + 3(-3)
= -5
6). 6y - 5x
6(-3) - 5(2)
= -28
Answer:
12.5 m²
Step-by-step explanation:
The shaded area is a triangle whose area (A) can be calculated as
A = 
bh ( b is the base and h the perpendicular height )
Here b = 8 - 3 = 5 and h = 5 , then
A = 
× 5 × 5 = 0.5 × 25 = 12.5 m²
