Step-by-step explanation:
first do the parenthesis
4x-3(3x+3x)>18
4x-3(6x)>18
4x-18x>18
-14x>18
I'm not sure if this helps but I tried
Answer:
90 miles
Step-by-step explanation:
1 1/2 is half of 3 so just multiply 45 by two
T - ( - 10) = 9
t + 10 = 9
t = 9 - 10
t = -1
----------------------------------
Answer: t = -1

Answer:
Step-by-step explanation:
Suppose that the side length is s. Imagine that one side is level. Draw a vertical line through the top vertex perpendicular to the base (level side). Label this vertical line "h." Then h and s are related as follows:
√3 h
sin 60 degrees = ------- = --------
2 s
s√3
and so h = the height of the triangle = -----------
2
The area of this triangle is (1/2)(base)(height), which here is:
(1/2)(s/2)( s√3 /2), or
(s^2)√3
A = ---------------
8
