To answer this use the Sign Rules
+*+ = +
-*- = +
+* - = -
- * + = -
(-8)(-8)(5)(5)(-8)=
(-8)*(-8) = 64
(64)(5)(5)(-8)
(64)(5) =320
(320)(5)(-8)
(320)(5) = 1600
(1600)(-8) = -12800
so
(-8)(-8)(5)(5)(-8)= -12800
Its 72 km apart you multiply 12 by the scale which is 1:6 so basically just 6
Answer:
<h2>
43</h2>
Step-by-step explanation:
2/10=.2, 6.2
6.2×6=37.2
37.2+6.2= 43.4
43.4= 43
(f+g)(x) = f(x) + g(x)
(f+g)(x) = [ f(x) ] + [ g(x) ]
(f+g)(x) = [ 3^x + 10x ] + [ 5x - 3 ]
(f+g)(x) = (3^x) + (10x+5x) + (-3)
(f+g)(x) = 3^x + 15x - 3
So the answer is choice D
