The length of each side of an equilateral triangle is increased by 5 inches so the perimeter is now 60 inches. write and solve an equation to find the original length of each side of the equilateral triangle.

A trainee has 3 sides and each side was increase by 5 inches.

Let x be the length of one side. You need to subtract 15 from the perimeter:

The equation can be 3x = 60 -15

Simplify:

3x = 45

Divide each side by 3:

X = 15

The original length of each side was 15 inches.

the 1st digit is in the 100s n its 1

step-by-step explanation:

3,589÷18 = 199.389

so the first digit of the quotient is in the 100s n its 1

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
