Answer:
The quadratic equation is (x + 3)(x + 4) = 5
Step-by-step explanation:
If the degree of a polynomial is two then the polynomial is known as a quadratic.
Now, in the given equations we see which polynomial has a degree 2.
Simplify the first equation

Degree is 3 and hence it is not a quadratic.
Take 2nd equation

Degree is 1 and hence it is not a quadratic.
Finally, we simplify the third equation

Apply FOIL method to simplify the left hand side

Degree is 2 and hence it is a quadratic equation.
Answer:
h(4)=-21
Step-by-step explanation:
h(v)=5x^2-28v+11
h(4)=5(4)^2-28(4)+11
h(4)=5(16)-112+11
h(4)=80-101
h(4)=-21

Answer:
Step-by-step explanation:
Quadrilaterals have angles that add up to 360, so sum all the angles and set them equal to 360. You should be able to solve for x here. Let me know if that doesn't quite make sense.
