Answer:
(x+1)^2+(y+1)^2=13
Step-by-step explanation:
Equation of a circle: (x – h)^2 + (y – k)^2 = r^2
center: (-1, -1)
radius: sqrt(6^2+4^2)/2=sqrt(52)/2=2sqrt(13)/2=sqrt(13)
Substitute those values in to get
(x+1)^2+(y+1)^2=13
G(x)=1
-3x2+18x+2
-6+18+2
6+2
8
Answer:
-15 < 20
Step-by-step explanation:
5(w - 3) < 5w + 20
Distribute;
5w - 15 < 5w + 20
Subtract 5w from both sides;
-15 < 20
The answer is 12 including both sides and angles.
When you cut a square piece of paper from one point to the opposite point it should make two triangles.
Thus each triangle has 3 sides and 3 angles so two triangles has 6 angles and 6 sides
So 12, sides and angles added together.
Answer:
base : 30 cm
height : 20 cm
perimeter : 92 cm
Area : 400 cm
Step-by-step explanation:
base : 30 cm
height : 20 cm
perimeter : 27 + 30 + 25 + 10
: 92 cm
Area : (1/2 ( a + b) ) x h
: (1/2 ( 10 + 30) ) x 20
: (20) x 20
: 400 cm
