If x^2+Mx+m is a perfect square trinomial, which equation must be true

Um i think you forgot to give us the answer choices

any way here is my answer ( x + M /2 )↑ 2 + m − M↑ 2/4

Step-by-step explanation:

What i did was use the formula (b/2)↑2 to create a new term to complete the square

The "/" signifies a fraction

the "↑"  signifies a exponent.

Hope it helps.

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743

step-by-step explanation:

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
