A scientists who studies insects enlarges a photograph of an elm leaf beetle every 2 inches in the photograph represents 8mm on the actual beetle the length of the beetle in the photograph is 1 1/2 inches .the width of the beetle in the photograph 3/4 inches what are the length and the width of the actual beetle show your work

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x

d

because parallelagram have all 4 angels the same size dependeing and a rectangle and square are oth parallelogram

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
