Answer:

3, 7

Step-by-step explanation:

"Zeros" means solutions to the equation f(x) = 0. In other words, what are the values of x that make the function's value equal to zero?

This one can be solved by factoring.

$x^2-10x+21=0\\(x-7)(x-3)=0\\x-7=0 \text{ or } x-3=0\\x=7 \text{ or } x=3$

Ivanshal [37]

Answer:

4.5 m

Step-by-step explanation:

Distance from center to the the bottom part where headroom begins is 3.9 m-2.6 m=1.3 m

Since the radius is 2.6 m and acts as hypotenuse(see attached image), then the other length will be

$\sqrt {2.6^{2}-1.3^{2}=5.07}=2.25166605
$

Approximately 2.25 m

The half width is 2.25 m hence full width will be 2.25*2=4.5 m
