9 + 3 × 2² - 1 × 4
= 9 + 3 × 4 - 1 × 4
= 9 + 12 - 1 × 4
= 21 - 1 × 4
= 21 - 4
= 17
Follow the order of PEMDAS, where,

Answer: its A
Step-by-step explanation:
The law of cosines states that:
c^2=a^2+b^2-2abcosC
You already have all the values for the variables with the exception of x so:
x^2=25+100-100cos60
x=√(125-100cos60)
x=√75
x≈8.66 to nearest one-hundredth...
