Answer: The simplified form by combining like terms is given by
Step-by-step explanation:
Since we have given that
Now, we combine the like terms :
1) First we collect m terms :
2) Combine n terms and constant terms :
Hence, the simplified form by combining like terms is given by
Answer:
Step-by-step explanation:
take angle A as reference angle
using cos rule
cos A=adjacent/hypotenuse
cos A=12/13
cos A=0.92
A=cos 23
A=23 degree
for ratio,
cos A=12/13
Adjacent angles in parallelograms are supplementary angles thus :
To find out how many quarts there are in 40 gallons, we simply need to know how many quarts there are in one gallon. As the name implies, there are 4 quarts in one gallon, so we simply need to multiply 4 * 40 to find the amount of quarts in 40 gallons.
4 * 40 = 160
There are 160 quarts in 40 gallons.
Hope that helped! =)
