Add -6 to both sides

square root x+6-6=7+-6

square root x=1

Solve square root

square root x=1

x= 1^2 ( square root both sides )

x=1

I hope that's help !

The answer is 1 because in 1st step we subtract 6 on both side and we get x=1 and square root of 1 is 1 itself

I honestly don’t get how to solve this

Answer:

Two other possible measure ments of AD and AE are

(a) Let AD = 4 units and AE = 6 units.

(b )Let AD = 2 units and AE = 3 units,

Step-by-step explanation:

In ΔABC, given

AB = 8 units, BC = 9 units, AC = 12 units,

D is on AB and E is on AC

Now, when AD = 6 and AE = 9, both ΔABC and ΔADE are similar.

Also, DB = 8 units - 6 units = 2 units,

EC = 12 units - 9 units = 3 units

⇒ $\frac{AD}{DB} = \frac{AE}{EC} = 3$

To adjust the points D and E in such a way, triangles REMAIN SIMILAR.

(a) Let AD = 4 units and AE = 6 units

Then, DB = 8 units - 4 units = 4 units,

EC = 12 units - 6 units = 6 units

⇒ $\frac{AD}{DB} = \frac{4}{4} = 1 , \\ \frac{AE}{EC} = \frac{6}{6} = 1$

⇒ $\frac{AD}{DB} = \frac{AE}{EC} = 1$

Hence, ΔABC and ΔADE are similar.

(b) Let AD = 2 units and AE = 3 units

Then, DB = 8 units - 2 units = 6 units,

EC = 12 units - 3 units = 9 units

⇒ $\frac{AD}{DB} = \frac{2}{6} = \frac{1}{3} , \\ \frac{AE}{EC} = \frac{3}{9} = \frac1}{3}$

⇒ $\frac{AD}{DB} = \frac{AE}{EC} =\frac{1}{3}$

Hence, ΔABC and ΔADE are similar.

Similar triangles have corresponding sides with proportional lengths.

AB/BC = DE/EF

5/9 = 7.5/EF

5(EF) = 9 * 7.5

5(EF) = 67.5

EF = 13.5
