Answer:
2.
4x^2 + 4 - 5x + x - 2x^2 + 8
= (4x^2 - 2x^2) + (x - 5x) + (4 + 8)
= 2x^2 - 4x + 12
=> D is correct
3.
2x^2 + 6x - 7x + 8 - 3x^2 + 1
= (2x^2 - 3x^2) + (6x - 7x) + (1 + 8)
= -x^2 - x + 9
=> C is correct
4.
B is correct (4 and 3)
Hope this helps!

Answer:
C = 14π cm
Step-by-step explanation:
C = πd
or
C = 2πr
Simply use the 1st equation and plug in the diameter to find you answer.
Flip over the second fraction
2 3/5= 13/5 ( Multiply the whole number with the denominator, 2*5=10 then add the numerator 10+3=13
-3 3/4= -15/4
13/5 * -4/15= -52/75
Answer :-52/75
Answer:
B = 6
Step-by-step explanation:
1. 4b + 8 = 6b - 4
2. Add 4 to both sides: 4b + 12 = 6b
3. Subtract 4b from both sides: 12 = 2b
4. Divide 12 by 2: b = 6
