Answer:
The expression that represents the length of 1 of the triangle's legs is y + 5
Step-by-step explanation:
An isosceles triangle has two sides equal which are the triangle legs. Let b represent the base of the triangle and l represent one of the triangle's legs. Then, the perimeter, P is given by
P = l + l + b
i.e P = 2l + b
From the question, P = 6y + 12 and b = 4y +2
∴ 6y + 12 = 2l + 4y + 2
6y - 4y + 12 - 2 = 2l
2y + 10 = 2l
∴ 2l = 2y + 10
Then,
l = (2y+10)/2
l = y + 5
Hence, the expression that represents the length of 1 of the triangle's legs is y + 5
Answer:
Step-by-step explanation:
A mixed number can be rewritten as the quotient of two numbers. <span>For instance, "1 and 1/4" = 5/4. 5 is not a multiple of 4 and therefore 5/4 is neither an integer nor a whole number. By definition, a mixed number has a nonzero remainder. Both integers and whole numbers have no remainder by definition, so it is impossible for a mixed number to be either.</span>
