1 answer:

3 0

Answer:

x = 4, y = 6, z = 2

Explanation:

Let x, y and z represent the 3 digit.

Where:
x = 2z
y = 3z
z = z

And: x + y + z = 12

2z + 3z + z = 12
6z = 12
z = 2

If z = 2 then:

x = 2(2) = 4
y = 3(2) = 6

(5+6b^3)^2 expand and combine like terms

Drupady [299]

Answer:

$( 5 + 6b^3)^2 = 36b^6 + 60b^3 + 25$

Step-by-step explanation:

$(a + b)^2 = a^2 + b^2 + 2ab$

So,

$(5 + 6b^3)^2 = (5)^2 + (6b^3)^2 + 2 (5)(6b^3)$

$= 25 + 36b^6 + 60b^3$
