- Isolate x for x + x + 10 = 10: x = 0
For y = 10
Substitute x = 0
Y = 0 + 10
0 + 10 = 10
y = 10
X = 0
Y = 10
If you mean proof that the opposite sides of a parallelogram are equal, you draw a diagonal then prove that the 2 triangles formed are congruent.
I think it’s C, correct me if I’m mistaken.
Answer:
Step-by-step explanation:
Two triangles are congruent by AAS postulate if two adjacent corresponding angles are congruent and the next adjacent sides to any of the angles is are also congruent. The adjacent sides should not be in between the two congruent angles.
From the triangles RQS and UTV
The adjacent side to is RQ and for is UT.
Similarly, the adjacent side to is QS and for is TV.
So, the possible sides that could be congruent by AAS postulate are:
or
So, the correct option is
You need 7 cartons, 4•7=28 so you’ll be sure to have enough:)
