Answer:
P=22cm
Step-by-step explanation:
L=8cm
b=(x–5)cm
A=(3x)cm²
we know that:
P=2(l+b)
and that
A=lb= 8(x–5)=8x–40
we have been given the value of A which is 3x, substituting into the equation for Area
=> 3x=8x–40
rearranging
=> x=8
therefore the breadth is (x–5)=(8–5)=3cm
=> P=2(8+3)=2(11)=22cm
hence, the perimeter of the rectangle is 22cm.
Answer: 193473

Answer:
124.77
Step-by-step explanation:
Matthew opened a checking account with 150
On Monday he bought lunch for 9.30 and wrote a check for 25.75
He deposited 75 on Wednesday
On thursday 65.18 was deducted from the account for his car insurance
The total expenses incurred on Monday can be calculated as follows
=9.30+25.75
= 35.05
This means that 35.05 will be debited from his account
On wednesday, he made a deposit of 75, this implies that a credit will be made to his checking account
On thursday, 65.18 was removed from his account for car insurance
Therefore since the initial balance of the account was 150 then, the remaining money that will be left in his account can be calculated as follows
= 150-35.05+75-65.18
= 124.77
Hence the money remaining in Matthew's account is 124.77
