Answer: Your answer should be B
Step-by-step explanation: Give brainliest if it works!
Given with the function of x which is f(x)=15x² + 360, we are tasked to solve for the value of x. The solution was discussed and shown below:
Set x=0, then we have:
0=15x² + 360
Transpose 360
15x²= -360
Divide by 15
x²= -360/15
x²= - 24
x = sqrt 4*6i
Therefore, the answer is letter B.
First what you want to do is get rid of the parenthesis by solving each expression: -7.9×6.2=-48.98
-4.5+8.2=-12.7
now just add them together: -48.98+(-12.7)=-61.68
So the answer to this expression is -61.68
