The isosceles triangle has a base that measures 14 units. A triangle has a base length of 14. The other 2 sides have a length of y. 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.

The sum of the first eight terms of an arithmetic progression is 9m + 14. the fifth term of the06 progression is 2m - 6, where m is a constant.given that the first term of the progression is 26,find the value of the common difference, d and thevalue of m.
