Step-by-step explanation:
A right triangle is a triangle in which one of the angles is a 90∘ angle.


Since None of the angels is 90° , so the triangle is not a right triangle.
The quadratic function has the form:
F(x) = y = a + bx + cx2
where a, b, and c are numerical constants and c is not equal to zero.
Note that if c were zero, the function would be linear.
An advantage of this notation is that it can easily be generalized by adding more terms. We could for example write equations such as
y = a + bx + cx<span>2 + </span>dx3
y = a + bx + cx<span>2 + </span>dx3 + ex<span>4</span>
Answer:
r=6
Step-by-step explanation:
6/11=r/11
cross product
11*r=6*11
11r=66
r=66/11
r=6
Answer:
Step-by-step explanation:
5 ( y - 2 ) + 3 ( 4 - y )
multiply 5 by both y and -2
5y - 10 + 3 ( 4 - y )
multiply 3 by by both 4 and -y
5y - 10 + 12 - y

Answer:
16 square feet is left uncovered.
Explanation:
Essentially, you’re trying to find the difference between the area of the door and the area of the poster. The area formula for a basic rectangle is l • w (length times width.) We have both of those dimensions for the separate shapes, so you can go ahead & do that math separately (as shown in the attachment!) Then, you subtract the area of the poster from the area of the door, and you have your answer. As always, I hope this is accurate & helpful! Good luck on your test, friend. Best wishes <3
