Solve each quadratic equation. Show your work. 4x^2=100

1 answer:

4 0

Hello there!

4x² = 100

We wanna start by dividing both sides by 4

4x²/4 = 100/4

x² = 25

Now we can take square root

x = +/-√25

x = 5 or x = -5

As always, it is my pleasure to help students like you!

Write an equation that expresses the following relationship.

AlexFokin [52]

The equation become u = k p^2 / d.

According to the statement

we have given that some conditions for the equations and we have t make the equation from the given equations.

So, For this purpose, we have given that

The equation in which u is varies directly with the square of p and inversely with d and use the k as the constant of proportionality.

So, From all these above the equation will become is

u = k p^2 / d

In latex form the equation write as :

$u = \frac{kp^{2}}{d}$

In this equation all the given conditions are applicable.

So, The equation become u = k p^2 / d

Help me?? i need help.

Answer:

$x = r - h$

Step-by-step explanation:

When solving for x, we want to get x all by itself on one side of the equals side. It doesn't matter which side.

In this case, we have x + h. Since we want x alone we have to get rid of the h. We can do this by subtracting h from both sides (whatever you do to one side, you have to do to the other side).

$r = x + h \\ r - h = x + h - h \\ r - h = x$
