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

Answer:
90
Step-by-step explanation:
The formula for right triangular prisms is simple; 1/2 × a × b × c. So simply plug in your numbers (doesn't matter the order you plug in).
1/2 × 12 × 5 × 3 = 90
Answer:
A triangle is 180 degrees. Imagine that two angles would be given as maybe 89 and 30 degrees. With these two angles already given you can find the last third angle by adding the 2 given angles and subtracting it from 180. There fore it would look like 180-119=61. 61 would be your unknown angle degree.
