I've done the first four questions. Use this method to answer the rest. For an odd number of objects find the cost of one and multiply by how many you are asked to find.
Perimeter is 2L x 2W or L + L + W + W
A) 12(2) + 24(2) = 72
B) 18(2) + 36(2) = 108
C) 27(2) + 54(2) = 162
D) 36(2) + 36(2) = 144 (and one side is not even twice the length of the other)
Answer: B
LCM of 15 & 6 = 30
then take the highest exponent for each variable
answer is:
30x^4y^8z^9
Answer:
Shalini = 12
Poonam = 60
Step-by-step explanation:
Let p = poonams age
Let s = shalini's age
p = 5s
p+s = 72
Substitute the first equation into the second equation
5s+s = 72
Combine like terms
6s= 72
Divide by 6
6s/6 = 72/6
s = 12
p = 5s =5*12 = 60
Shalini = 12
Poonam = 60
