Answer:
(a) Not congruent
Step-by-step explanation:
Angles are congruent, which means the triangles are <em>similar</em>. We need to know at least one pair of corresponding sides is congruent in order to say the triangles are congruent. No sides are marked, so we must conclude ...
Not Congruent
Let's solve the equation:
9x+27 = 9(x+2)+9 ← Distribute 9 to the x and 2
9x+27 = 9x+18+9 ← Combine like terms
9x+27 = 9x + 27 ← Subtract 27 from both sides
9x = 9x
Infinitely many solutions would be correct because no matter what x is, it will always equal each other the both sides of the equation because it is 9 times x on both sides.
Um, there are no choices, so I'll just tell you were it'd be located
Since 0.2 isn't yet 1, but its value is more than 0, it would be located in the middle of 1 and 0.
You have to turn the number or ratio and simplified the number and put it in to the chart like the norm number
