12*-9 is simply 12 * 9 with a negative at the end. I use a strategy as I'm in 8th grade that I learned in 5th this should help. If you love to hat that is bad. this is for division and multiplication this is stating that if a positive( love ) number times or divided by a negative( hate ) number it is negative( bad ). so 12*9=108 and add the negative and your answer is -108
Hope this helps:) good luck!
Answer:
True
Step-by-step explanation:
we know that
The <u><em>Trapezoid Mid-segment Theorem</em></u> states that : A line connecting the midpoints of the two legs of a trapezoid is parallel to the bases, and its length is equal to half the sum of lengths of the bases
see the attached figure to better understand the problem
EF is the mid-segment of trapezoid
EF is parallel to AB and is parallel to CD
EF=(AB+CD)/2
so
The mid-segment of a trapezoid is always parallel to each base
therefore
The statement is true
