Let's solve for x.<span><span><span><span>5k</span>x</span>+6</span>=<span><span>7k</span>x</span></span>
Step 1: Add -7kx to both sides.<span><span><span><span><span>5k</span>x</span>+6</span>+<span>−<span><span>7k</span>x</span></span></span>=<span><span><span>7k</span>x</span>+<span>−<span><span>7k</span>x</span></span></span></span><span><span><span>−<span><span>2k</span>x</span></span>+6</span>=0</span>
Step 2: Add -6 to both sides.<span><span><span><span>−<span><span>2k</span>x</span></span>+6</span>+<span>−6</span></span>=<span>0+<span>−6</span></span></span><span><span>−<span><span>2k</span>x</span></span>=<span>−6</span></span>
Step 3: Divide both sides by -2k.<span><span><span><span><span>−<span><span>2k</span>x</span></span><span>−<span>2k</span></span></span></span></span>=<span><span><span><span>−6</span><span>−<span>2k</span></span></span></span></span></span><span>x=<span><span>3/<span>k</span></span></span></span>

Answer:
40
Step-by-step explanation:
The scale factor of 5 to the side measuring 8 means that you multiply that side by the scale factor.
Basically, the equation would go like this:
Original Side Length: x
Scale Factor: y
New Side Length: z
xy=z
If we plug in our numbers, we get:
8*5=z
40=z
<u>40</u>
