Need help fast what are all the solution to this problem

Answers

Answer 1

Answer: x² - 25 = 0

The left side is the difference of 2 squares,
so we know right away, without any uncertainty
or sweat, that it can be written as

(x + 5) (x - 5) ,

and we know that it's equal to zero when either factor is zero.

Now let's look at the choices:

A. X = -1 Not a chance.

B. X = -3 Also no.

C. X = -5 Yes that's good; that would make the first factor zero.

D. X = 5 Yes that's good too; it would make the second factor zero.

E. X = 3 Not true. Don't know how they came up with it.

F. X = 1 Equally not true.

Answer 2

Answer: $x^(2) - 25 = 0 \n x^(2) = 0 + 25 \n x^(2) = 25 \n x = \pm √(25) \n \boxed{x = \pm 5}$

correct alternatives : C , D

Answer:

The roots of the given quadratic function $f(b) = b^2-75$ is $5√(3)\quad$ and $-5√(3)\quad$

Step-by-step explanation:

Given: Quadratic function $f(b) = b^2-75$

We have to find the roots of the given quadratic function $f(b) = b^2-75$

Since, roots of the quadratic equation is the points where the value of function is zero.

That is f(x) = 0

Consider the given function $f(b) = b^2-75$

Put f(b) = 0

$\Rightarrow b^2-75=0$

Simplify , we have,

$\Rightarrow b^2=75$

Taking square root both side, we have,

$\Rightarrow b=√(75)$

Simplify we have,

$\Rightarrow b=\pm 5√(3)\quad$

Thus, The roots of the given quadratic function $f(b) = b^2-75$ is $5√(3)\quad$ and $-5√(3)\quad$

Which one is the correct one

Answers

(Im doing Apex right now too! Im on the final for geometry and its terrible.)

Alright back to the answer

A wouldn't be it because many equations that have variables on both sides have solutions

B wouldnt be it because not having a solution means the equation does not have any value of X

So c is the answer. The equation can not be true for any variables for X because it does not have any solutions

Answers

Knowing the diameter of the can is 8cm, we can figure out the radius by dividing it by 2. The radius is 4cm. To find the volume of the can, multiply pi by radius^2 by height. (3.14)*(4)*(4)*(12)=(3.14)*(16)*(12)= (3.14)*(192)= 603 cm^3.
