The three numbers that make up the code to a safe sum 91. The last number is a multiple of 3, the middle number is 1/3 the last
Karolina [17]

Answer:

7

Explanation:

Let the middle number be x.

Since  the middle number is 1/3 the last number, then the last number has to be three times the middle number,

Therefore the last number is 3x

The first is 3 times the last number, meaning the first number has to be 3*3x=9x

All the three number add up to 91,

thus 9x+x+3x=91

13x=91

x=91/13=7

Choose the expressions that are sums or differences of two cubes. 64 a12b51 –t6 u3v21 8h45 – k15 75 – n3p6 –27 – xz9
alexandr402 [8]

A cube is an expression that has a power of 3

In algebra, the sum and the difference of two cubes are represented as:

\mathbf{x^3+y^3=(x+y)(x^2-xy+y^2)}

\mathbf{x^3 -y^3=(x - y)(x^2+xy+y^2)}

<em>The options are not clear, so I will give instances.</em>

\mathbf{(a)\ 64 - a^3}

To expand, we make use of:

\mathbf{x^3 -y^3=(x - y)(x^2+xy+y^2)}

Express 64 as 4^3

\mathbf{64 - a^3 = 4^3 - a^3}

By comparison:

x = 4, y = a

So, we have:

\mathbf{64 - a^3 =(4 - a)(4^2+4a+a^2)}

\mathbf{64 - a^3 =(4 - a)(16+4a+a^2)}

Hence, the expanded form of \mathbf{(a)\ 64 - a^3} is:

\mathbf{64 - a^3 =(4 - a)(16+4a+a^2)}

\mathbf{(b)\ 75 - n^3}

Rewrite as:

\mathbf{75 - n^3 = 5^3 - n^3}

Expand using: \mathbf{x^3 -y^3=(x - y)(x^2+xy+y^2)}

\mathbf{75 - n^3 = (5- n)(5^2 + 5n + n^2)}

\mathbf{75 - n^3 = (5- n)(25 + 5n + n^2)}
