Answer:
See answer below
Step-by-step explanation:
2b(2ab)² - a(2b²)² = XaY³(z - b)



X = 4
y = b
z = 2a
I could not see the first question so i couldn't answer.
2) Draw a horizontal line and cut it in half with a vertical angle. 4 equal quarters will form. There each quarter is 90° (right angle is exactly 90°angle)
3) Just add the two angles.
x =13+19
x= 32° (Answer)
4) We must know the other angle value in order to find x. So considering both the angles are equal,
2x = 44
x= 22° (Answer)
5) Yes, x = 80° because the line cutted is a straight line and the value of a straight line is 180°
6) Supplementary angles total 180°
Complementary angles total 90°
7)Opposite angles is equal when two straight lines intersect. So,
14x - 16 = 12x + 22
14x-12x=22+16
2x= 38
x= 19° (Answer)
8) Corresponding angles
9) 140°
Answer: You can use only common factor (3).

Answer:
Step-by-step explanation:
Total Students in Class = 25+ 15=40
Probability= (Number of Girls in Class) ÷ (Total students in Class)
Probability of girl= 15 ÷ 40 = 0.375
