Yuna ran three times as many kilometers so here expression should be 3k and the answer is 36.6
We have given that k = 12. 2
We have to find the expression
<h3>What is the writing and evaluating the expression?</h3>
Expressions are considered to be mathematical statements that have at least of two terms comprised of numbers or variables that should be linked. It could be of addition, subtraction, multiplication, or division.
Write the expression as 3k
Second, substitute 12.2 in for the variable, k.
Third, simplify by multiplying 3 and 12.2.
Therefore the answer is 36.6

Answer:
I think it is a binomial
Step-by-step explanation:
trinomial-three terms
Monomial-1 term
Binomial-2 terms
2 is common factor
2x=2(x)
4=2(2)
ab+ac=a(b+c)
2(x)+2(2)=2(x+2)

Answer:
Step-by-step explanation:
1. Area of a parallelogram = base * height
area = 10 * 4 = 40 in squared
perimeter = 2(a + b)
perimeter = 2 * (5 + 10) = 2 * 15 = 30in
2. Area of triangle = 1/2 * base * height
area = 1/2 * 21 * 8 = 84 cm squared
perimeter = sum of outer perimeters
perimeter= 10cm + 17cm + 21cm = 48cm
3. area of trapezium = 1/2 * (a+b) * h
area = 1/2 * (6+12) * 4 = 36ft squared
perimeter = sum of outer perimeters
perimeter = 5ft + 6ft + 12ft + 5ft = 28ft
