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: 41 plus 43 plus 45 plus 47.
Step-by-step explanation: n/a
1a+-1+a I believe that would be the answer
Answer:
i think it is A because that seems like the one making the most sense
Step-by-step explanation:
He would need exactly 20 more dimes.
42 x 18 = 756
776 divided by 756 = 20
