Find the value of x that satisfies the equation 7x + 22 = − 27 .

The perimeter of a trapezium is 52 cm and its non-parallel sides are each equal to 10cm . If its altitude is 8cm, what is its area?

Joe’s age is 16 years less than 5 times Jim’s age. Find Jim’s age if Joe is 9 years old.

Are the two polygons congruent? Explain why or why not.

Which of the following expressions is equivalent to the expression above?

Note:
Another way of solving this problem is to expand all the terms in the expression

Then we get,

Thus, we will get that

Can be written as

This also gives the same answer as above. No matter which method we use to simplify the expression, we will always get a unique answer.

△ DEF ≅ △ LMN
m∠D = m∠L = 70°
m∠F = m∠N = 30°
Which of the following statements is NOT true?

The parallel sides of a trapezium are 30cm and 10cm and the other two sides are 13cm, 21cm .find its area?

Draw the line of reflection for the word MOM

One hundred park-district members will be selected to participate in a survey about selecting a new park-district coordinator. Which of the following methods of choosing the 100 members would result in a random sample of members of the park district?

Note:
The method given is option A is called simple random sampling. Some other methods of random sampling are stratified random sampling, cluster random sampling and systematic random sampling.
Infact, there is further categorisation of simple random sampling- probability and non-probability sampling.

Find the area of a trapezium whose parallel sides measure 60cm and 77cm and non-parallel sides are 25cm and 26cm.

Find the image of the letter I after 180° rotation.

Identify all pairs of congruent corresponding parts. Then write another congruence statement for the
figures

Two polygons are considered to be congruent if the sides and angles match. When two sides or angles have the same length are considered to be congruent. We demonstrate that the angles are congruent by inserting the same slash marks through each one.
The symbol for congruence is ≅ and can be written as △ABC ≅ △DEF. ∠A is equivalent to ∠D, ∠B to ∠E, and ∠C to ∠F. Side AB corresponds to DE, BC to EF, and AC to DF.
Two triangles are formed with three sides that are congruent. Triangles are congruent if all three pairs of corresponding sides are congruent.

What is the angle of rotation followed by the given shape pattern?

A physician prescribes a treatment in which a patient takes 2 teaspoons of a medication every 6 hours for 5 days. According to the prescription, how many teaspoons of the medication should the patient take in a 24-hour period?

Note:
It may confuse some students but the fact that the medication needs to be taken for 5 days is not necessary to solve this question.

Identify and draw. We can also have line of reflection along the horizontal line.
