An equilateral triangle has 12in base its perimeter measures

Equilateral triangle means that all lengths of a triangle are the same, so if we are given one side of the triangle, 12in(the base), the rest of the sides are also 12in as well.

Since there are 3 sides to a triangle and one side measures 12 inches:

3 x 12 = 36 inches

perimeter =distance round a figure

sic

since an equilateral has all of its side equal

perimeter is 12×3

the answer is 36

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )
