Can someone please help

AleksandrR [38]

Answer:

(x+5) and (x-7).

Step-by-step explanation:

The given equation is :

$x^2-2x-35$

We need to write it in factored form.

We know that,

7×5 = 35 and 7-5 = 2

So,

$x^2-2x-35=x^2-7x+5x-35\\\\=x(x-7)+5(x-7)\\\\=(x+5)(x-7)$

Hence, the required factors are (x+5) and (x-7).

Question 3 options:

melomori [17]

The height of an object can be represented as a function of time.

It takes the rocket 25 seconds to hit the ground

The height function is given as:

$\mathbf{h(t) = 400t - 16t^2}$

When the rocket hits the ground, we have:

h(t) = 0

So, the height function becomes

$\mathbf{ 400t - 16t^2 = 0}$

Rewrite as:

$\mathbf{ 16t^2 = 400t}$

Divide both sides by 16t

$\mathbf{ t = 25}$

Hence, it takes the rocket 25 seconds to hit the ground
