What is the sum of the 12th square number and the 9th square number
Inessa [10]

Answer: 225

Step-by-step explanation:

<u>What is a square number</u>?

A square number is a product of a number times itself

So, the 12th square number would be 12 * 12, or 12²

The 9th square number would be 9 * 9, or 9²

The equation would be 12² + 9²

So:

12² + 9²

= 144 + 81

= 225

So, the answer is 225

Answer two questions about Equations AAA and BBB: \begin{aligned} A.&amp;&amp;\dfrac x4+1&amp;=-3 \\\\ B.&amp;&amp;x+4&amp;=-12
luda_lava [24]

The given equations are as follows

\begin{aligned} A.&&\dfrac x4+1&=-3 \\\\ B.&&x+4&=-12 \end{aligned}

(1) First, multiply both sides of equation A by 4, we have

4\times\left(\frac{x}{4} +1\right)=4\times(-3)

Then, rewrite the left-hand side of the above equation by using the distributive property, we have

4\times\frac{x}{4}+4\times1=4(-3)

\Rightarrow x+4=-12

This is the required equation B.

In this way, first use choice D: Multiply both sides by the same non-zero constant, i.e 4.

Then, apply choice A to solve the equation, i.e using the distributive property to solve the left-hand side of the equation.

(2) In the previous answer, equation B has been derived from equation A, hence, both the equations are equivalent.

As both the equations are the same, so both will have the same solution.

Yes, they have the same solution.
