Answer:

Step-by-step explanation:

The given equation is √2x+1+3=0

And we have been given that x= 4

I do not agree with the solution because it does not give any real solution. It only gives possible solution. If you plug the value 4 in the original equation you will get 8 and the square root of 8 is a complex number. Thus 4 is an extraneous solution....

16x² +8-7x-3x2 - 13x

liq [111]

Answer:

$13x^{2}$ -20x+8

Step-by-step explanation:

Step 1: rearrange the equation

16x^2 - 3x^2 - 7x - 13x +8

Step 2: solve the equation

16x^2 - 3x^2 = 13x^2

-7x - 13x = -20x

(the +8 will stay the same)

so when we put it all together it gives us

13x^2 - 20x + 8

Find the value of x, rounded to the nearest tenth <br> A. 24.5<br> B. 18<br> C. 16.1<br> D. 2

Strike441 [17]

Answer:

B. 18

Step-by-step explanation:

Given:

There are two chord in the circle.

These chords are divided in two segments.

Segments of 1 chord is 21 and 6.

Segments of 2 chord is x and 7.

Now by using Intersecting Chord Theorem which states,

"When two chords intersect each other inside a circle, the products of their segments are equal."

Hence from above theorem we can say that;

$x\times7=21\times6\\7x = 126\\x= \frac{126}{7}\\x=18$

Hence the Value of x is 18.
