Solution: Let x be the amount to be invested (15%).
Then,
x*0.15 + 550*0.11 = (x+550)*0.12
x*0.15 - x*0.12 = 550*0.12 - 550*0.11
0.03x = 550*(0.12-0.11)
0.03x = 550*0.01
0.03x = 5.5
x =5.5÷0.03
x=183.33
Answer: $183.33 more to be invested for 12 % total return.

Two triangles are said to be congruent when the have the same sides and the same angles. When a figure is dilated by a value, the size of that figure changes.
Therefore, when Triangle MNO is reflected across the y-axis and then dilated by a scale factor of 1.8 to form triangle MꞌꞌNꞌꞌOꞌꞌ, the two triangles are similar but not congruent.
(4c - 3d)(3c + d) =
= 12c² + 4cd - 9cd - 3d² =
= <u>12c² - 5cd - 3d²</u>
