Answer:
x=24
Step-by-step explanation:
The two angles form a straight line so they add to 180 degrees
4x-2 + 3x+14= 180
Combine like terms
7x +12 =180
Subtract 12 from each side
7x+12-12 = 180-12
7x = 168
Divide each side by 7
7x/7 = 168/7
x =24
(3x^3 + 4x²) + (3x^3 – 4x^2 – 9x) =
We have to combine like terms, terms that have x raised to the same power:
First, eliminate the parenthesis:
3x^3 + 4x² + 3x^3 – 4x^2 – 9x =
We have 2 terms raised to the second power (4x^2 and -4 x^2) simply add and subtract.
3x^3+3x^3+4x^2-4x^2-9x
6x^3-9x
Average of 5 games is no more than 74
So total 5 games with average 74 is:
74 x 5 = 370
First 4 games:
77+ 71 + 77 + 67 = 292
Find highest score on the last game
370 - 292 = 78
So highest score on the game 5 you can shoot is 78
Answer is B. 78
