Answer:
Look at the image.
Step-by-step explanation:
If 12 is 24%, then half of the percent is the actual number.
36% = 18
24% = 12
18% = 9
22% = 11
18 + 12 + 9 + 11 = 50

Step-by-step explanation:
Answer:
opening the bracket, the expression becomes
12x^2-28-19x^2
collect like terms
12x2-19x^2-28
-7x^2-28
-7(x^2+4)
All angles of a triangle sums up to 180 degrees
a° = 3a + 90 = 180°
3a = 180 - 90
3a = 90
a = 90÷3
a = 30°
b = 180-(25+90)
b = 180 - 115
b = 65°

Undistribute x (reverse the distributive proeprty)
ab+ac=a(b+c) so
mx+bx=x(m+b)
so
y=x(m+b)
divide both sides by (m+b)

=x
x=
