Solve <br> 1. x2 + x - 6 = 0
ololo11 [35]

Answer:

x = -3        x=2

Step-by-step explanation:

x^2 + x - 6 = 0

Factor

What two numbers multiply to -6 and add to 1

3*-2 =-6

3+-2 =1

(x+3) (x-2) = 0

Using the zero product property

x+3 = 0   x-2 = 0

x = -3        x=2

Find the value of x and y
Natalija [7]

Hello and Good Morning/Afternoon:

<u>Let's take this problem step-by-step</u>:

<u>What does the information want:</u>

  • value of x
  • value of y

<u>Let's gather some information</u>:

  • ΔA'BC' and ΔABC are similar triangles

             ⇒ Angle B is shared by both triangles

             ⇒ Angle A' and A are the same, as they are both on parallel

                   lines, A'C' and AC, and both angles are formed with the

                   same line AB

                 ⇒ by the <em>Angle-Angle Theorem*</em>, they are similar triangles

<u>If they are similar triangles</u>:

   ⇒ their side lengths are proportional to each other

  • let's find x's value

          ⇒ let's set up a proportion

                 \frac{A'B}{AB} =\frac{A'C'}{AC} \\\frac{30}{x+30} =\frac{14}{22} \\14(x+30) = 30*22\\14x + 420 = 660\\14x = 240\\x = 17.143

  • let's find y's value

          ⇒ let's set up a proportion

                 \frac{BC'}{BC} =\frac{A'C'}{AC} \\\frac{y}{y+15} =\frac{14}{22} \\22y=14(y+15)\\22y=14y+210\\8y=210\\y=26.25

<u>Answer:</u>

  • <u>x= 17.143</u>
  • <u>y = 26.25</u>

Hope that helps!

The simplified form of the expression 1/6 (30x + 24) – 1/7 (63 – 7x) will be 6x – 5.

The complete question is given below.

<h3>What is simplification?</h3>

Making anything easier to accomplish or comprehend, as well as making it less difficult, is the definition of simplification.

The expression is given below.

⇒ 1/6 (30x + 24) – 1/7 (63 – 7x)

By simplifying we have

⇒ 1/6 × 30x + 1/6 × 24 – 1/7 × 63 + 1/7 × 7x

⇒ 5x + 4 – 9 + x

⇒ 6x – 5

Then the simplification process is done.

More about the simplification link is given below.
