The polynomial -4x to the second power + 5 is considered by classification to be a

Quadratic Equation

Step-by-step explanation:

The equation's highest power is two and, therefore, is a quadratic.

Highest power:

0 > a line

1 > linear

2 > quadratic

3 > cubic

4 > quartic

5 > pintic

6 > mostly useless

4sqrt5

step-by-step explanation:

the base has dimensions of 8 x 4, so the diagonal is 64 + 16 square rooted or 4sqrt5.

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
