Explanation:
Any rhombus is a parallelogram, but not the other way around.
For any parallelogram, the opposite angles are congruent.
-8y-8 = 88
-8y = 88+8
-8y = 96
y = 96/(-8)
y = -12
Also, for any parallelogram, the adjacent angles are supplementary (meaning they add to 180).
(-3x+8) + (88) = 180
-3x+96 = 180
-3x = 180-96
-3x = 84
x = 84/(-3)
x = -28
And we can also say,
88 + (-9z-7) = 180
-9z+81 = 180
-9z = 180-81
-9z = 99
z = 99/(-9)
z = -11
Answer:
that's not quadratic formula or square method
Step-by-step explanation:
i personally thing the quadratic formula is easier which is
x = -b+-√b^2 -4ac
----------------------------
2a
you just plug in a b and c into the equation which is
x^2 is a which is 1
-6x is b which is -6
1 is c and its just 1
the answer also needs to involve a radical which for example 3√2
You didn't ask a question. That's just a statement.
235.24 + 45.58 = 280.82
280.82/2 = 140.41
each check was for $140.41
