I can't figure out the second answer please help!!!
Mekhanik [1.2K]

Choice A is one of the answers. Nice work. This is because x+x+x turns into 3x.

Choice D is the other answer because 2(x+1) + x = 2x+2+x = 3x+2. You can find this through trial and error. Or you could graph y = x+x+x+2 and y = 2(x+1)+2 to find that they are the same exact identical diagonal line. A non-graph approach would be to set up a table of values to see that the two tables are identical.

aleksandrvk [35]
I believe that they typo meant 300 fossils of which 21% are snail shells.

Since % means per one hundred...

300(21/100)=63

Elmer has 63 fossilized snail shells.

The length of a rectangle is 6m longer than its width. If the perimeter of the rectangle is 52m, find its area
sveticcg [70]
If length is x, then width is 6+x 
<span>Perimeter = 2*(x + 6+x) = 52 </span>
<span>2*6 + 2*2x = 52 </span>
<span>4x = 52 - 12 = 40 </span>
<span>x = 40/4 = 10 </span>

<span>Area = length*width = 10*(6+10) </span>
<span>Area = 10*16 = 160 meter square</span>
