Answer:
-25
Step-by-step explanation: When you multiply to negatives together you get a positive thus being shown in the problem -5 times -1 =5 then you multiply 6 times -5 and whenever you multiply a positive number by a negative you'll always get a negative number so 6 times -5 =-30 then you add 5 and -30 and you get -25. I hope this is right :D
<span>8.5 +4(1-2.5k) = -24.5
Use distributive property
8.5 + 4 - 10k = -24.5
Add 4 to 8.5
12.5 - 10k = 24.5
Subtract 12.5 from both sides
-10k = 12
Divide -10 on both sides
Final Answer: -12/10 or -1 2/10 or -1 1/5 *All answers are equivalent to each other.</span>
Using formula AB^2 = BD *(CD + BD)
AB^2 = 16 * (16+9)
AB^2 = 16 * 25
AB^2 = 400
AB = sqrt(400)
AB = 20
