Answer:
D) 26
Step-by-step explanation:
f(x) = 3x^2 - 6x + 2
Let x = -2
f(-2) = 3(-2)^2 - 6(-2) + 2
=3(4) +12+2
= 12 +12+2
=26

Step-by-step explanation:
The measure of angle PQR when Zubin drew a circle with right triangle will be 65°.
<h3>How to find the measure of the angle?</h3>
From the information given, when Zubin drew a circle with right triangle, arc QR measures 50 degrees.
Therefore, the measure of angle PQR will be:
= 180° - 90° - (1/2 × 50°)
= 180° - 90° - 25°
= 65°
In conclusion, the angle is 65°.

3a) Answer: 84 degrees
Step-by-step explanation:
3x + 2(x+20)= 180 (total sum of angles in a triangle is 180 degrees)
5x+40 = 180
5x = 140
x= 28
3x= 28 x 3
= 84
