21. a triangle has a base of 2c - 4 and a height
of 3c + 1. find a simplified expression that
represents the area.

correct answer is b. 27/8

step-by-step explanation:

try soting them out first

step-by-step explanation:

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130
