Answer:
B
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (7, 5) and (x₂, y₂ ) = (- 4, - 1)
m =
=
= 
Use either of the 2 points for (a, b)
Using (a, b) = (- 4, - 1), then
y - (- 1) =
( x - (- 4)), that is
y + 1 =
(x + 4)
FG goes through the center of the circle, so FG is diameter.

EH=r=3
Answer: EH=3
1) 43
2) 21
step by step:
Both triangles are right triangle which means they're equal to 90.
1) 23+24+X= 90
47+x= 90
x= 90-47
X= 43
2) 30+39+X= 90
69+X= 90
X= 90-69
X= 21
300.
1-4 round down or keep the place in front of it the same
while 5-9 round up
4: 25
l1=2
l2=5
surface area= 6*l^2
so for 1st =6*2^2
2nd= 6*5^2
ratio=6*2^2 /6*5^2
ratio= 4/25
or 4:25
