Answer:

<em>AB = 5√2</em>

<em>AC = √145</em>

<em>BC = √65</em>

Step-by-step explanation:

Using the formula for calculating the distance between two points

D = √(x2-x1)²+(y2-y1)²

For AB A(-3,6),B(2,1),

AB = √(2+3)²+(1-6)²

AB = √(5)²+(-5)²

AB = √25+25

AB =  √50

<em>AB = 5√2</em>

For AC A(-3,6) and C(9,5)

AC = √(9+3)²+(5-6)²

AC = √(12)²+(-1)²

AC = √144+1

<em>AC = √145</em>

For BC B(2,1), and C(9,5)

BC = √(9-2)²+(5-1)²

BC = √(7)²+(4)²

BC = √49+16

<em>BC = √65</em>

<em></em>

<em>Since All the sides are difference, hence triangle ABC is a scalene triangle</em>

Solve the equation.<br> 6x + 7 = 8x-15<br> help :(
Anvisha [2.4K]

Start by getting all terms with x on one side and all terms without on the other.

6x+7=8x-15

subtract 6x from both sides

7=2x-15

add 15 to both sides

22=2x

divide both sides by 2

11=x
