Answer:
1)2x^2 2)8x^3 3)4x-8
Step-by-step explanation:
1- you plug in x in g but nothing changes so then h and gyou just add 2- you plug in x in g again but once again, it remains the same so you just multiphy g and h and you get 8x^2 3- you plug in -2 into g to get 8 and then subtract it form h
Answer: ○| ̄|_ =3
the answer would be 2, because the 30 is increased from the 3 by times 10 so it would be the same for the 20, 20/10=2

Answer:
value of x = 2
Step-by-step explanation:
the given quadrilateral will be a parallelogram if their diagonals bisects each other so,
if 5x - 1 = 2x + 5 , then the given quadrilateral is a parallelogram.
now,
=》 5x - 1 = 2x + 5
=》 5x - 2x = 5 + 1
=》3x = 6
=》x = 6 ÷ 3
=》x = 2
hence, if x = 2 units, then the given figure will be a parallelogram.
Answer:
The measures of the acute angles are 38 and 52 degrees.
Step-by-step explanation:
In a right triangle, there are three angles, a right angle and two acute angles. In every traingle, the sum of the measures of the angles is 180 degrees. Let's call the acute angles and .
The problem also says that one angle is twice the difference of the other angle and 12. That would look like this:
Now we have two equations. If we simplify them, we get these:
Now you can substitute in the first equation for in the second equation
Add to both sides of the equation
Add to both sides
Divide both sides by 3
Now, you can substitute for in the first equation and simplify.
Therefore,
