1/tan(42)*18=20
Hope it helps
66 and 2/3 in a fraction would be 200/3 n lowest terms
You have to multiply 200 by 3 and add 2 to get 200
66 and 2/3 in a decimal would be 66.67
Divide 2/3 to get .67 and add 66.
Hi there!

To solve, we must use PEMDAS:
P: Parenthesis
E: Exponents
M: Multiply
D: Divide
A: Add
S: Subtract
Evaluate the inside of the parenthesis:
(124 + 6 × 8)
Multiply first:
(124 + 48)
Evaluate:
124 + 48 = 172
Divide by 2:
172 ÷ 2 = 86 = t
-1x(6x - 8)
= -x(6x - 8)
= -x(6x) - x(-8)
= -6x^2 + 8x
