Answer:
x=3⋅± 2
=±4.2426
x=0
Step-by-step explanation:
" Given f (x) = 3x + 2 and g(x) = 4 – 5x, find (f + g)(x), (f – g)(x), (f × g)(x), and (f / g)(x).1. = [3x + 2] + [4 – 5x] = 3x + 2 + 4 – 5x. = 3x – 5x + 2 + 4. = –2x + 6. (f – g)(x) 2. = f (x) – g(x)= [3x + 2] – [4 – 5x] = 3x + 2 – 4 + 5x. = 3x + 5x + 2 – 4. = 8x– 2. 3. ...= (3x + 2)(4 – 5x) = 12x + 8 – 15x2 – 10x. = –15x2 + 2x + 8. " - Google
Answer:
40,45,95
Step-by-step explanation:
The sum of the angles of a triangle are 180
2x+10 + 3x + 8x-25 = 180
Combine like terms
13x - 15 = 180
Add 15 to each side
13x - 15+15 =180 +15
13x = 195
Divide by 13
13x/13 = 195/13
x =15
The angles are
2x+10 = 2(15)+10 = 30+10 = 40
3x = 3(15) = 45
8x-25 = 8(15) -25 = 120-25 = 95
75 miles per hour means,
75 miles per 60 minutes.
And this makes 1.25 miles per 1 minute.
1 mile is 1760 yards.
So 1.25 miles is ;
1.25 * 1760 = 2200 yards.
Answer is 2200 yards per minute.
