Explanation: 24/8=3 3x3=9 9 coins are U.S coins 24-9=15 15 coins are foreign
15 coins= five eights so 3 coins are one eight if he adds twelve it’s going to be
4x3=12 so it’s seven eights.
The solution would be like
this for this specific problem:
A = (l + 20) · (w + 10)
The area of the pool is 1800 square feet and can be computed
also like l · w. Then l · w = 1800, and therefore l = 1800 w.
We plug in the values:
A = (1800 / w + 20) · (w + 10) = 1800 + 18000 / w + 20w +
200 = 18000 / w + 20w + 2000
dA /dw = − 18000 / w2 + 20
w = 30
l = 60
Since A = (l + 20) · (w + 10):
A = (60 + 20) · (30+ 10)
A = 3,200
<span>A(x) = 1800 + 2*10(x+10)+ 2*5(1800/x) </span><span>
<span>= 1800 + 20x + 200 + 18000/x </span>
<span>= 2000 + 20 x + 18000/x </span></span>
<span>20 - 18000/x^2 = 0 </span><span>
<span>x = sqrt (900) = 30 </span>
<span>Pool length dimension = 1800/x = 60 </span>
Lot dimensions: 80 x 40</span>
I am hoping that these answers
have satisfied your queries and it will be able to help you in your endeavors, and

Answer:
Here, BRX and NJY are two triangles in which,
BR = 30 cm, RX = 40 cm, BX = 60 cm, NJ = 15 cm, JY = 20 cm and NY = 30 cm,
Also, m∠B = m∠N, m∠R = m∠J and m∠X = m∠Y,
By the property of congruence,
, 
and 
Thus, By AAA similarity postulate,
Hence, proved.
