The perimeter of the scalene triangle is 54.6 cm. which equation can be used to find the value of b if side a measures 8.7 cm? a) 8.7 + b = 54.6 b) 17.4 + b = 54.6 c) 26.1 + b = 54.6 d) 34.8 + b = 54.6

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

the surface area is 124cm²
