Give the most precise name for the quadrilateral.
Then, find x and y.

A) square x=80 y=5
B) rhombus x=80 y=5
C) rhombus x=100 y=10
D) square x=80 y=10
E) rectangle x=100 y=7

B

Step-by-step explanation:

quadrilaterals= 360 degrees, now if you sub 80 for x, 80 +100 is 180 x 2( counting the other side) so 180 x 2 is 360

*I know there is a better way to explain it, but this is a way i find it

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

the equivalent expression are always the hardest ones but you look at the gcf also
