Answer
12 root 3
Answer is irrational (because it) can’t (and it’s decimal expansion) doesn’t (terminate or repeat)
You can see this by simply plugging the surd into the calculator
Step-by-step explanation
Sum of 2 root 3 and 5 root 12
Root 12 can be written as:
root 4 • root 3
root 4 = 2
= 2 • root 3
Multiply with the 5 from q
= 10 • root 3
Now the terms can be added
2 • root 3 + 10 • root 3 =
12 • root 3
Percent errors are calculated by dividing the absolute value of the errors by the exact length. What the student did wrong here is that he or she divided the given measurements by the exact lengths, which should not be the case.
Correct percent errors:
19 cm
percent error = (I19 - 20I / 20) x (100%) = 5%
21 cm
percent error = (I21 - 20I / 20) x (100%) = 5%

Question
Find the perimeter of a triangle with vertices A(2,5) B(2,-2) C(5,-2). Round your answer to the nearest tenth and show your work.
perimeter of a triangle = AB+AC+BC
Using the distance formula
AB = sqrt(-2-5)²+(2-2)²
AB = sqrt(-7)²
AB =sqrt(49)
AB =7
BC = sqrt(-2+2)²+(2-5)²
BC = sqrt(0+3²)
BC =sqrt(9)
BC =3
AC= sqrt(-2-5)²+(2-5)²
AC= sqrt(-7)²+3²
AC =sqrt(49+9)
AC =sqrt58
Perimeter = 10+sqrt58

Answer:
The equation representing the Martin's salary each day is: T = 100 + C
Step-by-step explanation:
Here, the per day FIXED salary of Martin = $100
Also, the amount earned by Martin in Commission = C
Let us assume the total salary of Martin each day = T
Now, the TOTAL SALARY of Martin = FIXED SALARY + COMMISSION
⇒ T = $100 + C
Hence, the equation which represents the Martin's salary each day is
T = 100 + C
