Answer:
40 rows will hamsters fill
Step-by-step explanation:
As per the statement:
There are 486 hamsters at a private showing of a new documentary about humans.
⇒Total number of hamsters = 486
It is also given that there are 12 seats in each row.
then;
They will fill = 
Therefore, the best estimate the rows will hamsters fill is 40 rows.
Answer:
D
Step-by-step explanation:
Look at the graph. You want to see how much distance he is at 9 minutes. Go all the way to 9 minutes, then go up. What coordinate does it fall in? (9,80). He travelled 80 meters in 9 minutes. (D)
Every triangles 3 angles will always add up to 180 degrees
The reason this is true in your problem is because of the corresponding angles and supplementary angles.
Hope this helps
Answer:
2x⁴+x³-x²+54x+56
Step-by-step explanation:
Given the expression length of dylan room = (x² – 2x + 8) and width = (2x² + 5x – 7), assuming the shap of the room is rectangular in nature, the formula for calculating area of a triangle is given as;
Area of rectangle = Length *Width
Area of the rectangle = (x² – 2x + 8)(2x² + 5x – 7)
Area of the rectangle = x²(2x² + 5x – 7) - 2x (2x² + 5x – 7) + 8(2x² + 5x – 7)
= (2x⁴+5x³-7x²)-(4x³+10x²-14x)+(16x²+40x-56)
expanding the bracket
= 2x⁴+5x³-7x²-4x³-10x²+14x+16x²+40x-56
Collecting the like terms;
= 2x⁴+5x³-4x³-7x²-10x²+16x²+40x+14x+56
= 2x⁴+x³-x²+54x+56
Hence, the expression that represents the area (lw) of Dylan's room is 2x⁴+x³-x²+54x+56
