* will mark brainliest - if you give an explanation* The length of each side of an equilateral triangle is (4x - 7) cm. Write an equation to determine the value of x that will produce a triangle with a perimeter of 27 cm.

3(4x-7)=27
12x-21=27
12x=48
x= 4

x = 4cm is your answer.

brainliest would be appreciated

Answer to your question: a. the fundamental theorem of algebra tells you that the equation will have two complex roots since the degree of the polynomial is 2. the roots are ​ x=1±i7√2 .number of roots=degree of polynomialhere, degree of polynomial is 2 so number of roots will be 2.hope it *_*
