What is the solution set for x2+25=0

Masja [62]

Step-by-step explanation:

${x}^{2} + 25 = 0 \\ \therefore {x}^{2} = - 25 \\ \therefore {x} = \sqrt{ - 25} \\ \therefore {x} = \pm\sqrt{ - 1 \times 25} \\ \therefore {x} = \pm \sqrt{ 25} \times \sqrt{ - 1} \\ \therefore {x} = \pm5 \: i \\ \therefore {x} = \{ - 5i, \: \: 5i \} \: \\ is \: the \: solution \: set.$

Read the question on the picture.

These two lines are congruent (the same) so we can set them equal to each other and solve.

5x-4=3x+6

The first thing we need to do is subtract 3x from both sides leaving us with 2x-4=6

Now we can add 4 to both sides leaving us with 2x=2

Now we need to divide both sides by 2 to get x alone.

Giving us our final answer of x=1

What is the value of x please help me

Tju [1.3M]

Answer:

<h2>x = 4</h2>

Step-by-step explanation:

ΔLMN and ΔPMQ are similar. Therefore thw sides are in proportion:

$\dfrac{LM}{PM}=\dfrac{NM}{QM}$

We have:

LM = 3 + 9 = 12

PM = 9

NM = x + 12

QM = 12

Substitute:

$\dfrac{12}{9}=\dfrac{x+12}{12}$ <em>cross multiply</em>

$9(x+12)=(12)(12)$

$9(x+12)=144$ <em>divide both sides by 9</em>

$\dfrac{9(x+12)}{9}=\dfrac{144}{9}$

$x+12=16$ <em>subtract 12 from both sides</em>

$x=4$
