For this question you can just divide the both sides by -7 so you gonna have :
-7b/-7 = -42/-7 ⇒ b = 6 :)))
i hope this is helpful
have a nice day
The new perimeter will be 3 times the old perimeter.
Original perimeter:
2(8+7) = 2(15) = 30 yds
New perimeter once they are tripled:
3 x 8 = 24
3 x 7 = 21
2(24+21) = 2(45) = 90 yds
30 x 3 = 90
Answer:
72
Step-by-step explanation:
The interior angles of a 6 sided figure add to (n-2) * 180
where n is the number of sides
(6-2) *180
4*180
720
2x+4x+4x+4x+4x+2x = 720
20x = 720
Divide by 20
20x/20 = 720/20
x =36
We want <F
<F = 2x = 2*36 = 72
Given:
The endpoints of line segment CD are C(-2,0) and D(4,9).
To find:
The midpoint of CD.
Solution:
Midpoint formula:
Using the midpoint formula, the midpoint of CD is
Therefore, the midpoint of the line segment CD is (1,4.5).
