Answer:

x=3

Step-by-step explanation:

x^2 = 6x - 9

Subtract 6x from each side

x^2 -6x = -9

Add 9 to each side

x^2 -6x+9 = 0

Factor  

what 2 numbers multiply to 9 and add to -6

-3*-3 = 9

-3+-3 =-6

(x-3)(x-3) = 0

Using the zero product property

x-3 =0    x-3=0

x=3 with multiplicity 2

Ab= 6cm Ac=12cm <br> Calculate the length of Ad <br> Give your answer to 3 significant figures
Allisa [31]

Answer:

12.686cm

Step-by-step explanation:

By using pythagoras, we can find CB.

We know that a^2+b^2=c^2

Therefore, 12^2-6^2=CB^2

CB=\sqrt{108} (it has to be positive since it is distance)

now we look at triangle BCD and use SOH CAH TOA.

Sin55=CB/CD\\Therefore, CD= 12.686

Lisa and Marie are both on the track team. During practice, Lisa ran 10 laps around
Zigmanuir [339]

Answer:

Marie ran at a faster rate. It takes 27 minutes for Lisa to run 15 laps while it takes Marie 26.25 minutes to run 15 laps.

Step-by-step explanation:

18 ÷ 10 = 1.8 (Lisa's rate)

14 ÷ 8 = 1.75 (Marie's rate)

1.8 x 15 = 27 minutes (How long it takes for Lisa to run 15 laps)

1.75 x 15 = 26.25 (How long it takes for Marie to run 15 laps)
