I dont have paper with me but just solve 2(-2)^3+2 for the first one. The second one is -28 though
$403.75
Step 1: 415(.15)
Step 2: 475 - 415(.15)
Step 3: 403.75
The correct answer is C.) c=5
This is correct by using the equation c^2=a^2+b^2
c^2=3^2*4^2
c^2=9+16
c^2=25
Square root of c=square root of 25
c=5
