Answer:

$x = \frac{ - 3}{2} \: or \: \frac{1}{3}$

Step-by-step explanation:

$7 {x}^{2} + 10x - 3 = {x}^{2} + 3x$

$= > 7 {x}^{2} - {x}^{2} + 10x - 3x -3 = 0$

$= > 6 {x}^{2} + 7x - 3 = 0$

$= > 6 {x}^{2} + 9x - 2x - 3 = 0$

$= > 3x(2x + 3) - 1(2x + 3) = 0$

$= > (2x + 3)(3x - 1) = 0$

Here x will have 2 values.

1) $2x + 3 = 0$

$= > 2x = - 3$

$= > x = \frac{ - 3}{2}$

2) $3x - 1 = 0$

$= > 3x = 1$

$= > x = \frac{1}{3}$

Describe the relationship between GF and CD when the two lines are perpendicular to AB. Also describe the relationship between G

Tamiku [17]

Answer:

congruent

Step-by-step explanation:

If two lines intersect to form a linear pair of congruent angles, then the lines are perpendicular. When two adjacent angles form a linear pair, their non-shared sides form a straight line (m).
