Answer:

AC=\frac{27}{2}

Step-by-step explanation:

We are given a Triangle ABC , and DE││BC , where D and E lies on AB and BC Respectively. As DE││BC , ABC is similar to BDE. Hence the ratios of the respective sides will be equal . Hence

\frac{BD}{AB}=\frac{DE}{AC} ----------(A)

Given BD=2

BA=BD+AD=2+7=9

DE=3

Putting these values in (A)

\frac{2}{9}=\frac{3}{AC}

AC=  \frac{3 \times 9}{2}

AC=\frac{27}{2}

X^2+ 6x - 4 = 3x + 6
jolli1 [7]

Answer:

x=2

x=-5

Step-by-step explanation:

You need to get everything on one side to have a quadratic equation:

x^2+6x-4 -(3x+6) = x^2+3x-10

All factors of 10 are 1*10 and 2*5.

5-2 = 3 and 5*-2 = -10

Factoring x^2+3x-10 gives us (x-2)(x+5)

x=2

x=-5
