to. find.
area of the rectangle
given
decreased. 25•/•
increased.40•/•
solusion
Length = L
Breadth = B
Original area = L x B
New area = A = L x (1 - 25%) x B x (1 + 40%)
A = L x B x 0.75 x 1.40 = L x B x 1.05
Therefore the area of the rectangle has increased by 5%.

Answer: x=10
Step-by-step explanation:

Answer:
Jack solved 9 probelms
John solved 21 probelms
To solve this problem we can make some equations
John = JO
Jack = JA
JO = 2JA + 1
JA + JO + 28
since we have two equations we can just substitute in the value for JO and solve.
JA + 2JA + 1 = 28
3JA = 27
JA = 9
Then we can check our answer
19 = 2(9) + 1 this is true
9 + 19 = 28. also true.
