Hi there!
First we need to work out the parenthesis, which can for instance be done using rainbow technique.
Now subtract 3 from both sides.
And finally add 3x to both sides.
The 4th answer choice is correct.
The length is 54 ft because 13.5 in. is equal to .25*54 so 1*54 would be your answer in feet.
Equation
10x1/2+(-6) (-3)
Answer

Answer:
1. ft 2. yards 3. units.
Step-by-step explanation:
Pythagorean's Theorem
A and b are both side lengths, c is the hypotenuse.
7^2 + 5^2 = 74
sqrt(74) is the answer for 1.
30^2 - 5^2 = 875
Simplify the radical. sqrt(875) --> 5sqrt(35). The answer for three.
There's a rule in geometry that says a diagonal of a square is the same length as taking a side length times the square root of two. There's your answer for two.
