Answer:
282.74
Step-by-step explanation:
2 dimes and 4 nickels
.10+.10+.05+.05+.05+.05=.40 or 40 cents
63+81=9(7+9)
You can check your answer by:
9(7+9)
9(7+ )=63
9( +9)=81
Multiplying the GCF by every term in the parenthesis.

Trying to factor as a Difference of Cubes
2.1 Factoring: 8x2y3-5
Theory : A difference of two perfect cubes, a3 - b3 can be factored into
(a-b) • (a2 +ab +b2)
Proof : (a-b)•(a2+ab+b2) =
a3+a2b+ab2-ba2-b2a-b3 =
a3+(a2b-ba2)+(ab2-b2a)-b3 =
a3+0+0+b3 =
a3+b3
Check : 8 is the cube of 2
Check : 5 is not a cube !!
Ruling : Binomial can not be factored as the difference of two perfect cubes
Final result :
8x2y3 - 5
