Answer:
Step-by-step explanation:
It is a rectangle, so both sides are equal. Thus 2x+6=5x-9
SOLVE, SUBTRACT 2x
6=3x-9 THEN ADD 9
15=3x THEN divide by 3
5=x
Plug in x to either side 2(5)+6, to get side length of 16
Then area of a rectangle is lengthxwidth=AREA
substitute what you know 16(y)=48
Divide by 16, thus y=3
M = 1,000
D = 500
C = 100
L = 50
X = 10
V = 5
I = 1
MDCCXLIV
M = 1,000
DCC = 500 + 100 + 100 = 700 (smaller after larger, then adding)
XL = 50 - 10 = 40 (smaller before bigger, then subtraction)
IV = 5 - 1 = 4 (smaller before bigger, then subtraction)
<h3>MDCCXLIV = 1,000 + 700 + 40 + 4 = 1,744</h3>

I think the answer is x2 + 3x -28 and the x2 is x to the POWER of 2
Answer:
6) x=9.75
10) Triangle OMN ~ Triangle ODK; SSS ~
11) SSS ~ theorem
12) SSS ~ theorem
Step-by-step explanation:
For #6, since the polygons are similar, then it must mean AD is congruent to JM and CD is congruent to LM. Now we can set up the proportion 39/20=x/5 and solve. Solving for x gets us x=9.75, so C is the correct choice
For #10, there's no information about angles whatsoever in the diagram, so B and C must be wrong. D must be wrong as well because if the triangles weren't similar, then why is OJ ~ JM and OK ~ KN? So thus, the triangles are similar by SSS.
For #11, this is sort of a no-brainer because there's no mention of angles, so D must be correct.
For #12, same concept, no mention of angles, all sides are similar to their respective sides of the different triangles, so A is correct.
