Q(2a , 0)

R (2b, 2c)

Midpoint QR

x = (2a + 2b)/2

= 2(a+b) / 2

= a + b

y = (0+ 2c)/2

= 2c/ 2

= c

Midpoint QR (a + b, c)

Answer: third option

(a + b, c)

Solve for x! Please help!

erica [24]

Answer:

Step-by-step explanation:

ΔADC and ΔCDB are similar (AA). Therefore the sides are in proportion:

$\dfrac{AD}{DC}=\dfrac{DC}{DB}$

We have AD = 16, DC = x, DB = 9. Substitute:

$\dfrac{16}{x}=\dfrac{x}{9}$ <em>cross multiply</em>

$x^2=(16)(9)\to x=\sqrt{(16)(9)}\\\\x=\sqrt{16}\cdot\sqrt9\\\\x=4\cdot3\\\\x=12$
