Answer:
trapezoid.
Step-by-step explanation:
A trapezoid is a convex quadrilateral. A trapezoid has at least on pair of parallel sides. the parallel sides are called bases while the non parallel sides are called legs
Characteristics of a trapezoid
It has 4 vertices and edges
If both pairs of its opposite sides of a trapezoid are parallel, it becomes a parallelogram
Area of a trapezoid = 
x (sum of the lengths of the parallel sides) x height
Perimeter = sum of lengths of sides of a trapezoid
Answer:
(2x + 4) ( x +1 ) are factors .
Step-by-step explanation:
Given : 2x² + 9x + 4.
To find : Factor.
Solution : We have given that 2x² + 9x + 4.
On factoring 2x² + 8x + 1x + 4.
Taking common 2x from first two terms and 1 from last two terms .
2x ( x +4 ) +1 (x +4 ).
On grouping
(2x + 4) ( x +1 ).
Therefore , (2x + 4) ( x +1 ) are factors .
Answer:
Vertex form: 
Standard form: 
Step-by-step explanation:
A quadratic function in vertex form is 
where 
is the vertex.
We are given 
.
Let's plug that in:
.
Now let's find 
.
We will use the 
-intercept 
to find .
So the function in vertex form is:
.
In standard form, we will have to multiply and combine any like terms.
Let's do that:
Please provide a square, thank you !!!
