Step-by-step explanation:
I can't see pictures, but I'll try to do what I can.
2+4x+10=1
Combine like terms.
(2+10)+4x=1
12+4x=1
Subtract 12.
12+4x=1
-12 -12
4x=-11
Divide 4.
4x=-11
/4 /4
x=-2.75

Answer:
The answer to your question is sin Ф = 4/5
Step-by-step explanation:
From the picture, we know that ∠C is a right angle, so ΔABC is a right triangle.
To solve this question use trigonometric functions
sin Ф = Opposite side / hypotenuse
Opposite side = 4
Hypotenuse = 5
Then,
sin Ф = 4/5
Step 1 is to factor everything!
After factoring you will get:
x-5 over (x+2)(x+5) times x+4 over (x-3)(x+4)
Step 2 is to remove the duplicate factors!
Remove x+4 and x+5
x-5 over (x+2)(x-5) times 1 over x-3 = 1 over x+2 times 1 over x-3
Step 3 is to multiply the numerators and the denominators.
End result is 1 over (x+2)(x-3)
1/3 plus 2/3 = 1 whole
