The perfect square is a number that is the product of two identical numbers. So 9 is a perfect square because it's the product of 3 * 3. For variables, perfect squares can be expressed as (x+a)^{2} or (x-a)^{2}, where a is some number and x is the variable.
If we expand these terms, (x+a)^{2}=x^{2}+2ax+a^{2}, and (x-a)^{2}=x^{2}-2ax+a^{2}. Since the given term is x^{2}+10x, we can see that it's part of the perfect square x^{2}+2ax+a^{2}. We just need to find a^{2}.
So, x^{2}+2ax+a^{2}=x^{2}+10x+a^{2}. Notice that 10=2a, so a=5. So, the missing constant term is 5^{2}=25. The perfect square is (x+5)^{2}.

AlekseyPX

Answer:

Option (3)

Step-by-step explanation:

Joe has a ruler which has markings for each millimeter, so the least measurement which Joe can do is in millimeter.

Since, 10 mm = 1 cm

Therefore, 1 mm = 0.1 cm

This rule states that Joe can measure a length or distance in nearest tenth of a cm only.

If length of a box = 13.67 cm,

So Joe can measure it as 13.7 cm approximately.

Therefore, Option (3) will be the answer.

OLEGan [10]
The <u>correct answer</u> is:

Experiment

Explanation:

In an experiment, one group is given a treatment while at least one other group is not.  After the treatment is finished, the results of the group that receive the treatment are compared with the results of the group (or groups) that do not receive the treatment, to determine if the treatment had any effect on the group.

In this problem, the different groups are the classes.  Some classes use the new method, which is the treatment, while other classes do not.  At the end of the year, the reading results of each class are compared to see if the treatment (new method) had any effect.
