Answer:

  • 3x² + 5x + 1 = 0 simplified
  • x = (-5 ± \sqrt{13})/6 roots

Step-by-step explanation:

<u>Given quadratic formula</u>

  • 3x² + 5x - 5 = - 6

<u>Standard form</u>

  • ax² + bx + c = 0

<u>Simplifying</u>

  • 3x² + 5x - 5 + 6 = 0
  • 3x² + 5x + 1 = 0

<u>Solving</u>

  • x = (-5 ± \sqrt{5^2 -4*3*1})/(2*3)
  • x = (-5 ± \sqrt{13})/6

Solve for x. −18 = −2/3 x
vredina [299]

Answer:

x = 27

Step-by-step explanation:

To isolate x, we can multiply it by the reciprocal of the fraction (-3/2). We do the same to the -18.

Through cross-multiplication, -18/1 x -3/2 simplifies into -9/1 x -3/1 (because 2 goes into 2 once and 2 goes into -18 -9 times).

-9 x -3 = 27; therefore, x = 27

Find the area. The figure is not drawn to scale
poizon [28]

Answer:

96 square inches.

Step-by-step explanation:

From given picture we see that

BC=8 in

AD=10 in

Given that

AD=AB

Then AB=10 in

Apply Pythagorean theorem in triangle ABC to find AC

(hypotenuse)^2=(base)^2+(perpendicular)^2

(AB)^2=(BC)^2+(AC)^2

(10)^2=(8)^2+(AC)^2

100=64+(AC)^2

100-64=(AC)^2

36=(AC)^2

take square root

6=AC

Then area of triangle ABC =\frac{1}{2}\left(base\right)\left(altitude\right)

=\frac{1}{2}\left(8\right)\left(6\right)=24

There are total 4 congruent triangles.

Then total area of the given figure = 4(24)=96 square inches.
