<u>SOLUTION</u><u>:</u>

<u>what should be added to a²-2ab+b² to get a²-ab-2b² </u>

let the added no is P

  • \pmb{P+(a^2-2ab+b^2)=(a^2-ab-2b^2) }

  • \pmb{P=(a^2-ab-2b^2)-(a^2-2ab+b^2) }

  • \pmb{P=a^2-ab-2b^2-a^2+2ab-b^2 }

  • \pmb{P=ab-3b^2 }

\therefore{\pmb{ab-3b^2 }} should be added to a²-2ab+b² to get a²-ab-2b²

From the photo below can someone solve question 50 please.
Pie
Question 50.

a. Description

You walk 0.5 miles during 10 minutes, stop and wait for the bus during 4 minutes, then ride the bus for 2 miles during 4 minutes.

b. slopes

the slope of each line represents the average speed of every track.

1) first track

slope = 0.5 miles / 10 minutes = 0.05 miles / minutes.

Given that the slope is constant, you walked at a constant speed of 0.05 miles/minute.

2) second track

slope = 0 => you didn,t move (you were waiting the bus)

3) third track

slope = (2.5 - 0.5) miles / (18 min - 14 min) = 2 miles / 4 min = 0.5 miles / min

means the speed of the bus was constant and equal to 0.5 miles / min.

Whats the 11th term of 2,6,18,54
Natalija [7]
The 11th term would be 39,366.

The rule for this sequence is 3n (n times 3). Simplying multiplying by 3 until you get to the 11th term (54 * 3 * 3 * 3 * 3 * 3 * 3), would give you this answer.

I hope this helps!!
