<h3>
Answer: Choice A which is (m+6)^2</h3>
Explanation:
Think of two numbers that multiply to 36 and add to 12. Those two numbers are 6 and 6
6+6 = 12
6*6 = 36
So we can factor it into (m+6)(m+6). Use the FOIL rule to expand it out to get m^2+12m+36 back again.
The expression (m+6)(m+6) is the same as (m+6)^2
Answer:
175 Kg
Step-by-step explanation:
Convert 385 pounds into kg given the fact that 1 kg = 2.2 pounds.
385 : 2.2 =
175 Kg

Answer:
<em>2(x) + 2(x + 3) = 90 </em>
Step-by-step explanation:
Width: x inch.
Length: (x + 3) inch.
P = 2 
+ 2 
P = <em>2(x) + 2(x + 3) = 90</em>

Five less than quotient of x and three
Answer:
Step-by-step explanation:
Let the rate of boat in still water be b and the speed of the current be c
- Speed downstream = b + c
- Speed upstream = b - c
<u>We got equations for time:</u>
- 108/(b - c) = 3 ⇒ b - c = 36
- 108/(b + c) = 2 ⇒ b + c = 54
<u>Add up the equations:</u>
- b - c + b + c = 36 + 54
- 2b = 90
- b = 45 km/h
<u>Then finding the values of c</u>
