42/2 = 21

21 = w +2w+3

21 = 3w +3

18 =3w

w = 18/3 = 6

width is 6

length = 6x2=12+3 = 15

6+6+15+15 = 42

width = 6 m

length = 15 m

Solve the quadratic equation using the quadratic formula: 3x^2 - 6x = 5

Fantom [35]

Answer:

$x_{1} = 1+\frac{2\sqrt{6}}{3} \\\\x_{2} = 1-\frac{2\sqrt{6}}{3}$

Step-by-step explanation:

3x^2 - 6x - 5=0

quadratic formula:

$x=\frac{-b+-\sqrt{b^{2}-4*a*c}}{2*a}$

a=3 b=-6 c=-5

$x=\frac{-(-6)+-\sqrt{(-6)^{2}-4*3*-5}}{2*3}$

$x=\frac{6+-\sqrt{36+60}}{6} \\\\x=\frac{6+-\sqrt{96}}{6} \\\\x=\frac{6+-\sqrt{2^{2}*2^{2}*2*3 }}{6} \\\\x=\frac{6+-4\sqrt{6}}{6} \\$

so we have:

$x_{1} = 1+\frac{2\sqrt{6}}{3} \\\\x_{2} = 1-\frac{2\sqrt{6}}{3}$

(Will give brainliest) Is my answer correct?? If not please correct me

Hey!

-------------------------------------------------

Answer:

(-6, 2) and (-7, -1) and (0, 0)

-------------------------------------------------

Explanation:

You reflected the triangle. You needed to translate the triangle.

y + 6 is to move up 6 units along the y-axis.

x - 5 is to move left 5 units along the x-axis.

Another thing, the question doesn't state was transformation to use so we are going to assume we are translating.
