MN = √2
it comes from √(1^2 + 1^2) = √2 (use phytagoras)

LK = 2 x MN = 2 √2

NK = √(2^2 + 1^2) = √5

ML = NK = √5

so the perimeter
√2 + 2 √2 + √5 + √5
3 √2 + 2 √5

I need help with math it’s urgent thanks

Artemon [7]

Answer:

(1, 3)

Step-by-step explanation:

2x + 3y = 11 ------------(i)

-4x + 2y = 2 ------------(ii)

Multiply equation (i) by 2.

(i)*2 4x + 6y = 22

(ii) <u>-4x + 2y = 2</u> {Now add and x will be eliminated}

8y = 24

y= 24/8

y = 3

Plugin the value of y in equation (i)

2x + 3*3 = 11

2x + 9 = 11

2x = 11-9

2x = 2

x = 2/2

x = 1

If a bank account doubles in size every 5 years, then by what percent does it grow after only 3 years? Round to the nearest tent

mr Goodwill [35]

Answer:

Step-by-step explanation:

Alright, let get started.

Suppose the initial deposit in account = x

After five years, this accounts get doubled means = 2x

Means in 5 years , the growth = $2x-x = x$

So, in 1 year, the growth will be = $\frac{x}{5}$

So, in 3 years, the growth will be = $\frac{x}{5}*3=\frac{3x}{5}$

So percent grwoth will be = $\frac{\frac{3x}{5}}{x}*100 = 60$

Hence percentage growth is 60 %. : Answer

Hope it will help :)
