Sqrt( 7x ) + 1 = sqrt( 7x + 1 )

Solve it?

Answers

$√(7x) +1 = √(7x+1)$

First isolate a square root on the left side:
$√(7x) = - 1 + √(7x+1)$

Now, delete the radical on the left side, Raise both sides squarely:
$(√(7x))^2 = (-1+ √(7x+1) )^2$

Thus:
$7x = 1 - 2 √(7x+1) + 7x + 1$
$7x = 7x+1+1-2 √(7x+1)$
$7x = 7x+2-2 √(7x+1)$

Find the radical remainder by isolating a radical on the left side again:
$2 √(7x+1) = -\diagup\!\!\!\! 7x+\diagup\!\!\!\! 7x+2$
$2 √(7x+1) = 2$

Now, delete the radical on the left side, Raise both sides squarely:
$(2 √(7x+1))^2 = (2)^2$

Solving, We have:
$2^2(7x+1) = 4$
$4(7x+1) =4$
$28x+4 = 4$
$28x = \diagup\!\!\!\! 4 -\diagup\!\!\!\! 4$
$28x = 0$
$x = (0)/(28)$
$\boxed{x = 0}$

Confirm that the solution is correct
Statement equation
$√(7x) = - 1 + √(7x+1)$

*Replaces "0" in "x"
$√(7*0) = - 1 + √(7*0+1)$
$√(0) = - 1 + √(0+1)$
$0 = - 1 + √(1)$
$0 = - \diagup\!\!\!\! 1 + \diagup\!\!\!\! 1$
Solution:
$\boxed{0 = 0}$ (TRUE)

The sum of the angle measures of any trapezoid is greater than the sum of the angle measures of any parallelogram.

Answers

Answer:

False. Trapezoids and parallelograms are both types of quadrilaterals. 4 sided figures. The sum of a quadrilateral's angles is always equal to 360. The sum of a trapezoid's angles, as well as the sum of a parallelogram's angles, will always be equal. I hope this answers your question.
