Use 

Answer: Without rounding : 13.64 (square cm)
Rounded answer : 13.6(square cm)
Step-by-step explanation:
We know that the area of a rectangle is given by :-
, where l is the length and w is the width of the rectangle.
Given : The dimensions of a rectangle are 3.1 cm wide and 4.4 cm long.
Then, the area of rectangle will be:-

Therefore, the area of rectangle =
Answer:
x^2-3x+36
Step-by-step explanation:
Answer:
I believe y = 90°
Step-by-step explanation:
70 + 110 = 180, so you know that both sides are the same angle. The angle of the two straight lines must be 90°
Answer:
The vertex is (-1, 3)
Step-by-step explanation:
The form this is in is called vertex form. We can express the equation using its base form.
y = a(x - h)^2 + k
Now we can identify the vertex as (h, k). By looking at the equation, we can see h is equal to -1 and k is equal to 3.
