I believe it is a parallelogram.
Reasons:
1. It is a quadrilateral. Quadrilaterals have a total amount of 360 degrees. 80+100+100+80=360
2. It has oposite sides that are equal
3. If you look at a parallelogram it has two obtuse angles and two acute.
100= obtuse angle 80= acute angle

with that template in mind, let's see, it went to the right 2 units, and then up 3 units.

that simply means, C = -2, D = 3.

The number 9.37 rounded to the nearest tenth is 9.4 Is this correct?y or y not

PSYCHO15rus [73]

Yes, this is correct. The tenths place is the first number to the right of the decimal. There is a 3 in that spot
To find if it rounds up or down, follow this rule.
Less than 5 round down and greater than 5 round up.
For this you look to the number next to it which is 7.
It rounds up so it is 9.4
