Question

Help on #'s 14 and 20 please :)
thanks

Answer 1

Thanks

Answer 2

#14 is a kite

#20: just set the congruent sides equal to each other
2x -3.5 = x + .5

2y-2.8 = y+2

Answer 3

so X=? and Y=?

Answer 4

you tell me, solve each equation by getting the variable by itself on one side

Answer 5

so, 3 and 3.6?

Answer 6

not quite

2x -3.5 = x + .5

subtract x on both sides

x -3.5 = .5

add 3.5 on both sides

x = 4

Answer 7

so x=4 and y=4.8?

Answer 8

yep :)

don't forget to now plug those values back in to find the side lengths
