Answer: x = 20.
Step-by-step explanation:
x and (3x + 10) combine to form a right angle, shown in the diagram by the small square joining the perpendicular lines.
Right angles are 90 degrees, so you can add both angles to get 90:

Answer:
12
Step-by-step explanation:
f(x) = 2x^2 - 5x
Let x=4
f(4) = 2 (4)^2 -5(4)
Exponents first
= 2*16 -5*4
Multiply
=32 -20
subtract
=12
In order to add these fractions we have to make a common denominator.
1/5 can turn into 2/10 Its the same thing. And its easier to solve with.
now lets multiply.
× 
Now we add across
2 + 1 = 3
------------
10 + 10 = 10 ( When adding fractions like these the denominator stays the same)
So your answer is...

Good Luck! :)
