For what value of r is the parallelogram a rhombus
Gre4nikov [31]

Answer:

9

Step-by-step explanation:

7r+18=r²

r²-7r-18=0

factorizing

r²+2r-9r-18=0

r(r+2)-9(r+2=0

(r-9)(r+2)=0

r-9=0

r=9

(r²)=(9*9)=81

7r+18=7(9) + 8=81

What is the value of x?<br><br> What is the value of y?
Rudik [331]

Answer:

Y= 20

X= 25

Step-by-step explanation:

The angles of a triangle have to equal 180

So

80+60 = 140

180 - 140 = 40

40/2 = 20

Y = 20

The angles of a linear line split equal 180

So

2y is one side of it which we learned Y = 20 which makes that side 40

To find the other side just guess and check

6(25) = 150

150 - 10 = 140

So the 2y = 40 and the (6x-10) = 140

So yea boom done
