(3x + 1/2 ) + ( 7x - 4 1/2 )
3x+7x + 1/2 - 4 1/2
10x -4
90 square ft (try and look at it like each side is a 2d rectangle, find the areas of the sides and then add them up.)
Answer:

Step-by-step explanation:
If the point (2,3) is on the terminal side of an angle in standard position.
Adjacent of O, x=2,
Opposite of O, y=3
Next, we determine the hypotenuse, r using Pythagoras Theorem.

Therefore:



Answer:
x=15
Step-by-step explanation:
(10*9)/6=10*x/10
90/6=x
15=x
