On a website there is an ad for jeans every 5 minutes, an ad for sneakers every 10 minutes, and add for scarves every 45 minutes. they all appeared together at 9 p. m. when is the next time they will appear all together?

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
