Answer:
12k^5 +24k⁴+30k³
Step-by-step explanation:
the area = 6k³(2k²+4k+5)
= 12k^5 +24k⁴+30k³
Answer:

Step-by-step explanation:
-10 (d+1) = -14
-10d -10 = -14
-10d = -14 + 10
-10d = -4
d = 4/10
d= 2/5
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:
x = -5
y = 0
Step-by-step explanation:
x-y = -5 -----eqn 1
x-y = 1/3 ------eqn 2
From eqn 1
x-y = -5
x = -5 + y -----eqn 3
From eqn 1
-5+y-y = -5
y = 0
Eqn 3
x = -5 + 0
x = -5
