The isosceles triangle has a base that measures 14 units. The value of y, the length of each leg, must be equal to 7. between 7
and 14. greater than 7. between 14 and 28.
2 answers:
1.The isosceles triangle has sides of length 14, y, y
2. According to the "triangle inequality" :
y+y>14
2y>14
y>14/2=7
(y is greater than 7)
3. Remark, check the figures:
the side lengths cannot be less than (neither equal to 7), because we cannot get a triangle in that case, check picture 2
In picture 1 wee see that the side lengths can be as large as we want. We can erect an altitude, as high as we want. Pick a point on the altitude, and join it to the endpoints of the base, and we get an isosceles triangle with base equal to 14.

Answer:
Step-by-step explanation:
Let we consider sales of home in January as first term for sequence, then sales in February will be 2nd term and so on.
According to the given information, we have
First term :
Second term :
Third term :
We can see that, Common difference = 7
Explicit rule for Arithmetic sequence :
Put and d=7
The required explicit rule that can be used to find the number of homes sold in the nth month of the year :
