Answer:
12.73m
Step-by-step explanation:
using Pythagoras theorem
a = x (i change x to a for easy reference due to multiplication)
18 x 18 = a x a + a x a
324 = 2a^2
a^2 = 324 / 2= 162
a =

Answer:
-86
Step-by-step explanation:
simplify each equation as much as possible
f(x)= 4x(2+9) add
4x(11) multiply
f(x)=44x
substitute given numbers into each equation
44(-2)=-88 3(4)-14= 12-14=-2
combine equations
-88-(-2)= -86 add since you are subtracting a negative number
Angle CBA is the right name because it's in between C and A
