A plane is defined as a figure that has B, two dimensions.
This question is about definitions, and the definition of a plane is that it is a flat surface with two dimensions. But, since everything in our world is 3 dimensions (everything, even if it looks small, has some kind of depth), there are no planes in our world. A plane also extends infinitely far, and can be named by 3 points on it.
Answer:

Step-by-step explanation:
We are given zeros as x=-4, x=-2
so, we can set up function as

Vertex is at (-1,3)
It means that graph passes through point (-1,3)
so, we can plug x=-1 and f(x)=3
and then we can solve for 'a'

we get

now, we can plug it back
and we get

now, we can simplify it

Answer:
80 degrees
Step-by-step explanation:
the sides add upp to 180 degrees so 180-70-30=80
Area of rectangle = length x width If length is constant, say c and width is variable, say x Area of rectangle = y = cx This means Area will vary linearly with width and will represent a line with slope... hope I helped
