4(x-3) - 5x > -1
4x - 12 - 5x > -1
-x > -1 + 12
-x > 11
x < -11
<em><u>Answer:</u></em>
12.8 or option 3
<em><u>Step-by-step explanation:</u></em>
So this is actually a proportion:
The large triangle to the smaller one:
<em>The angles of the triangles are the same so they are proportional</em>
We know the larger one is 20/8 times the smaller one's sides because
<em>YZ = something times QR so:</em>
20 = 8 times 20/8
In order to find PR, we have to divide ZX by the proportion rate thing so:
32 / (20/8)
= 32 * 8/20
= 64/5
= 12.8
A: 100 because a perfect square is just a number squared and 10 squared is 100 :)
-7x-3x+2=-8x-8 | combine like terms
-10x+2=-8x-8 | add 8x
-2x+2=-8 | subtract 2
-2x=-10 | divide by -2
x=5
The answer would be D because V= side length times 3
