Answer:
f(x) = -60 is your answer
Step-by-step explanation:
Plug in 3 for x
f(x) = 5x² - 7(4x + 3)
f(x) = 5(3²) - 7(4(3) + 3)
Follow PEMDAS. First, solve the parenthesis
3² = 9
4(3) + 3 = 12 + 3 = 15
f(x) = 5(9) - 7(15)
Multiply
f(x) = 45 - 105
Simplify. Subtract
f(x) = 45 - 105
f(x) = -60
f(x) = -60 is your answer

The answer is B.
The only reason it will be 200 is because the numbers 1,2,3,4,5,and 6 are all an option so the probability of 5 is 1/6 and if you multiply 1/6 by 1,200 you will get 200. Hope this helped!
When measuring a penny, using the millimeter measurement would be more accurate then using inches or centimeters.
I believe the correct answer from the choices listed above is the third option. The total area of the frame would be expressed as A = <span>x^2+12x+36. </span>

Step-by-step explanation:
when they have the same variable you can add them together. When adding 10x and --10x, the cancel out (negate) and you are left with 0
