In this problem, a, b, c and d are nonzero integers. if a/b is added to x, the sum is c/d. which statement can be used to prove that x must be a rational number? x = cb+ad/bdx = cb-ad/bdx = c+a/d-bx = c-a/d-b

The correct answer would be x = cb-ad/bd.

In order to get this, you would need to first solve the equation for x and then standardize the denominator on the right side. Below if the work for you.

a/b + x = c/d > subtract a/b from both sides

x = c/d - a/b > multiply c/d by b/b

x = cb/bd - a/b > multiply a/b by d/d

x = cb-ad/bd

The correct answer would be x = cb-ad/bd.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

there has been genes found in the x chromosome of males that have been linked to [homo/hetero]sexuality. in addition to the reign of the x chromosome, a section of chromosome 8 has also been link to, "alot of ppl are so " these facts were proven true after a 2014 study of a gay male and his strait brother. according to newscientist.com,"chromosome 14 and is mainly active in the thyroid, but also the brain. called tshr, it makes a type of receptor protein that recognises and binds to a hormone that stimulates the thyroid. in this way, the gene plays an important role in controlling thyroid function. the fact that tshr seems to be involved in sexual orientation fits with evidence that thyroid function seems to be linked to sexuality."

in conclusion, "ppl are so gay" due to their genetics.
