Answer:
d = 
Step-by-step explanation:
6(2c + 3d) = 5(4c - 3d)
6(2c) + 6(3d) = 5(4c) - 5(3d) distribute out the terms
12c + 18d = 20c - 15d
18d + 15d = 20c - 12c get all like terms onto the same side
33d = 8c
d =
divide by 33 to isolate the d variable
Answer:
8a^3
Step-by-step explanation:
Given that;
2^x = a, we want an expression for 8^(x + 1)
we have this as;
8^(x + 1) = 8^x * 8^1
8^x = (2^x)(3)
8^x is thus same as 2^3x
So replace 2^x by a
Thus, we have a^3
Multiply this by the 8 we had initially; that will give;
8 * a^3 = 8a^3
