Answer:

see explanation

Step-by-step explanation:

Given that $l_{1}$ and $l_{2}$ are parallel lines then

a = 35 ( alternate angle )

The sum of the angles in a triangle = 180°, thus

b = 180 - (90 + a) = 180 - (90 + 35) = 180 - 125 = 55

b and c form a straight angle, thus

c = 180 - b = 180 - 55 = 125

d = 55 ( alternate to b )

Using the quadratic formula to solve 4x^2-3x + 9=2x + 1 what are the values of x

Alchen [17]

Answer:

x=5±√−103/8

Step-by-step explanation:

There's no real solutions

4x2−3x+9−(2x+1)=2x+1−(2x+1)

4x2−5x+8=0

x=−b±√b2−4ac/2a

x=−(−5)±√(−5)2−4(4)(8)/2(4)

x=5±√−103/8

Determine whether the polynomial below can be factored into perfect squares. If so, factor the polynomial. Otherwise, select tha

kkurt [141]

Answer:

A. $=(9x-12)^2$

Step-by-step explanation:

We need to determine whether the polynomial $81x^2-216x+144$ can be factored into perfect squares. If so, factor the polynomial. Otherwise, select that it cannot be factored into a perfect square.

$81x^2-216x+144$

$=9(9x^2-24x+12)$

$=9(9x^2-12x-12x+12)$

$=9(3x(3x-4)-4(3x-4))$

$=9(3x-4)(3x-4)$

$=9(3x-4)^2$

$=3^2(3x-4)^2$

$=(3(3x-4))^2$

$=(9x-12)^2$

Hence choice A. $=(9x-12)^2$ is correct.
