The correct answers are:

B=(xy + x)(xy + x) ; C=(2x – 3)(–3 + 2x) ; and E=(4y² + 25)(25 + 4y²)

Explanation:

In order to have a perfect square trinomial, we must multiply two binomials that are exactly the same. For (xy+x)(xy+x), are multiplying two identical binomials.

For (2x-3)(-3+2x), we are multiplying two binomials that are the same but written in a different order. The same is true of (4y² + 25)(25 + 4y²).

Suppose △JCD≅△MAY.

Kisachek [45]

The correct answer for this would be ΔCJD ≅ ΔAMY and ΔDCJ ≅ ΔYAM.
All we are doing for this is rearranging the order of the angles, as long as the order of the angles match with the original order.
The following answers are also correct:
ΔDJC ≅ ΔYMA
ΔCDJ ≅ ΔAYM
ΔJDC ≅ ΔMYA

Find the measure of angle QPR. Given m m m Find m

Dennis_Churaev [7]

Since Angle QPS is a straight angle, it equals 180 degrees.

Angles QPR and RPS equal QPS.

Angle QPR + Angle RPS = QPS

(7x-4) + (9x-40) = 180

A sample of 92 observations is taken from a process (an infinite population). the sampling distribution of x̄ is approximately n

Sindrei [870]

It is normal based on the Central Limit Theorem. According to the theorem, an appropriately big sample (infinite) size from a population with a limited level of variance, the average of all samples from the same populace will be roughly equivalent to the mean of the population.
