Emma called the following figure a trapezoid which of the following proves emma is correct a- the figure has two pairs of opposite sides that are marked congruent b- the figure has one side of opposite sides that are marked congruent c- the figure has one pair of opposite sides that are marked parallel d- the figure has base angles marked congruent

A shape is said trapezoid if it has at least one pair of parallel sides.

Hence, C- the figure has one pair of opposite sides that are marked parallel would be the answer.

for me what is finding a good play list and going out because i can not lay down and relax so i usually go to a coffee shop. i also use the gum trick and this actually works. another advice is highlighting subjects it really does me remember certain things

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
