Answer:
-384
Step-by-step explanation:
f(x) =x^2+8x
evaluate f(x)=-16
input -16 for x
-16^2+8(-16)
-16^2= -256
then, 8*-16=-128
add the two negatives
-256+-128= -384

Answer:
The boat travels (300.4 km / 11 hours) which is 27.30909091 kilometers per hour, So it would take 240 / 27.30909091 hours or 8.78828229 hours. (Which rounds off to 8.79 hours)

Answer:
1. d 2. a 3. d 4. a 5. a
Step-by-step explanation:
For 1, d is negative because, if there an even number of negatives, the answer will be positive. a. would have been correct, but you multiply that one by 0. 0 is not negative, so the answer has to be d.
2. is -21. You can multiply 3 times seven then make it negative, or simply add -7 together 3 times.
3. is d because the two negatives cancel each other out. Even numbers of negatives cancel each other out. therefore, 17 times 6 is 102.
4. -120 is the answer because there are 3 negatives. That is an odd number, so we know our answer is negative. -5 times -3 is 15, and 15 times -8 is -120.
5. is a because -1 times 4 is -4, then -4 times -9 is 36. 36 times -3 is then -108.
