Answer:
y = 
Step-by-step explanation:
multiply 
by 
to get 
:
+ y - 
= 
simplify:
y + 
=
subract from both sides:
y =
Let x units be the length of the shortest side of the triangle.
Perimeter of triangle = 2(x + 1) +x = 3x + 2
Perimeter of square = 4(x - 2) = 4x - 8
Equating the two expressions for perimeters, we get:
3x + 2 = 4x - 8
The solution is: x = 10
The answer is 10 units.

Step-by-step explanation:
(√3+√7)²
We know ,[(a+b)²=a²+2ab+b²]
=>(√3+√7)²=(√3)²+2(√3)(√7)+(√7)²
=>(√3+√7)²=3+2√21+7
=>(√3+√7)²=10+2√21
Answer: (total amount paid - $40) / 0.05
Step-by-step explanation:
Given the following :
Monthly fee = $40
Additional fee = $0.05 per minute on phone
Given the the amount paid for the month is available, number of minutes he was on phone can be determined thus :
Total amount to be paid = monthly fee + additional fee
Additional fee = $0.05 × n
Where n = number of minutes on phone
Hence,
Total amount paid = $40 + $0.05n
If the amount paid is known, the number of minutes on phone can be calculated thus;
(Total amount paid - monthly fee) = $0.05n
n = (Total amount paid - monthly fee) / fee per minute on phone
(total amount paid - $40) / 0.05
