Answer:
Yup! Great Job!
Step-by-step explanation:
343: 49 × 7 = 7^2 × 7 = 7^3
125: 25 × 5 = 5^2 × 5 = 5^3
x^12(7x+5)(49x^2 -35x + 25)
x^12(7x+5)(7x-5)^2
Let's solve your equation step-by-step.

</span>Step 1: Simplify both sides of the equation.
<span><span><span><span><span>3m</span>+<span>1m</span></span>−7</span>+<span>3m</span></span>=21

</span><span><span><span>7m</span>−7</span>=21
</span>Step 2: Add 7 to both sides.
<span><span><span><span>7m</span>−7</span>+7</span>=<span>21+7
</span></span><span><span>7m</span>=28
</span>Step 3: Divide both sides by 7.
<span><span><span>7m/</span>7</span>=<span>28/7

</span>Answer:<span>m=<span>4</span></span>
Answer is : -7
Reason: 5(-2)=-10
-10+3=-7
10. √7=irrational numbers
11.
15x - 20
------------ = 15x-4
5
