Hello,
sin(-45°)=-√2 /2 =-0,7071067....
Angle CP = 45 degrees, because it's bisecting a right angle (90 degrees) and half of 90 degrees is 45.
Answer:
20+h = 46
Step-by-step explanation:
it doesn't ask to solve it so that's the answer
Let me answer those two questions in the reverse order.
1). How it can be solved:
7x + 5 = 3x - 11
Subtract 3x
from each side: 4x + 5 = - 11
Subtract 5
from each side: 4x = - 16
Divide each side
by 4 : x = - 4
2). The answer is x = - 4 .
-4 is called the 'solution' to the equation, because that's the number
that 'X' MUST be. If it's any other number, then the equation is not
a true statement.
Answer:
Step-by-step explanation:
hello :
let : f(x) this denominator :
12/x(x+4) = f(x)/x(x+4)(x-9)
f(x) =12x(x+4)(x-9)/x(x+4)
if : x(x+4)(x-9)≠0 simpify by : x(x+4)
f(x) = 12(x-9)
