You would set it up like this: 150x + 280 = 255x The you just solve.
Answer:
784
Step-by-step explanation:
(30+4)(23+3)
Answer:
x=13
Step-by-step explanation:
Well, the triangle is always equal to 180 degrees in total. Lets remember that x will always be the same in every equation.
So, (5x-11) x (2x+20) x (11x-63) = 180.
Now, take away the parenthesis and add up all the like terms.
This should = 18x-54 = 180.
Now solve like you regularly would. Add 54 on both sides which equals,
18x=234. Now, divide 18 on both sides.
x = 13.
Hope this helps.
The correct answer is a because all you do is expand it it's just the same thing but longer
