Answer:
2x + 12
Step-by-step explanation:
Example of Associative Property Addition:
a + (b+c) = b + (a+c)
Now, implement it to the given expression:
(2x+8) + 4 = 2x + (8+4)
That simplifies to:
2x + 12
Step-by-step explanation:
Divide 7 by 24
You will get the answer
True or False question, I would say that it's true.
Since we know that the area is 100 and we are dealing with a square, that means that all sides are equal. We know that the sides are all 10 because 10*10= 100.
To find the perimeter, we add up all the sides: 10+10+10+10 = 40m
There is only 1 remaining side
We have 2 sides and an included angle, we use the Law of Cosines to solve the third side:
c^2 = a^2 + b^2 -2ab *cos(C)
c^2 = .5^2 + .333333333...^2 - 2 * .5 * .3333333... * cos (95)
c^2 = .25 + .1111111111111111... -2*.5*.3333333333...* -0.087156
c^2 = 0.3611111111 + 0.029052
c^2 = 0.3901631111
c = 0.6246303796
