Solution:
<u>Note that:</u>
- Given inequality: 3 < x + 3 < 6
<u>Solving the inequality one by one.</u>
- 3 < x + 3
- => -3 + 3 < x
- => 0 < x
- => x + 3 < 6
- => x < 6 - 3
- => x < 3
The inequality is <u>0 < x < 3.</u>
Answer:
Side MQ is similar to side MR.
- This is because since M is the mid point of QR, both MQ and MR are half of QR.
Angle MXQ and MYR are 90°
Sides QX and RY are similar.
- This is because angle X and Y are 90° and MQ and MR are equal.
∴ MQX is congruent to MRY.
Answer:
48 units
Step-by-step explanation:
1. Perfect square trinomials, are 2nd degree polynomials, of the form

so that

, which can be written as perfect squares.
2. For example

3. Thus

are perfect square trinomials.
4.

5. In the first case -b=20, so b=-20. In the second case, -b=-20, so b=20.
6. b∈{-20, 20}
