Okay so you have to do
138 times .40-move the decimal over 2 times
that is 55.2 so 40 percent of 138 is 55.2 so add that on to 138 to get 192 students at the school. There you go :)
<span>If two triangles are congruent, then the six corresponding parts are congruent.</span>
(x + 4)*3 - 4 = 65
3x + 12 - 4 = 65
3x = 65 - 12 + 4
3x = 57 |:3
x = 19 <-- Answer
(19+4)*3-4 = 23*3-4 = 69-4 = 65
64 inches is the correct answer. To get it you need to multiply the length times the width.
(this is incorrect. Sorry for the inconvenience)
