Answer:
Bigger size / smaller size = 40
Step-by-step explanation:
Notice that we
36 / (9/10) = 30 / (3/4) = 40
Therefore the proportion model would be
84+n=342
you would subtract 84 from 342 to find the width since it is perimeter.
I believe the second one is d
A. f(-2)=3-6(-2)
-2f =3-(-12)
-2f=3+12
=15
divide both sides by 2
f=15/2
B. f(0)=3-6(0)
f=3
C.f(4)=3-6(4)
4f=3-24
f=21/4
<2=40° <11=60°
Because <1 was 140°, 2 is 40°. 40°+80°=120°
180°-120°=60°
