Answer:
x = 10
Step-by-step explanation:
3x + 55 = 9x - 5 (add 5 to both sides)
3x + 55 + 5 = 9x - 5 + 5
3x + 60 = 9x (subtract 3x from both sides)
60 = 9x - 3x
60 = 6x (rearrange)
6x = 60 (divide both sides by 6)
x = 60/6
x = 10
Answer:
chicken nuggets to the moon
Step-by-step explanation:
20°+120°+I°=180°
I=40°
using sine rule,
I/sin I=x/sinX
12/sin40=x/sin20
x=12sin20/sin40
x=6.4
using similarly and enlargement,
we have, cw/cp=y/120
8/12=y/120
y=80°
Y= 1 - 5x^2
now, f(3) = 1 - 5 (3)^2
= 1 - 5(9) = -44
