(2x + 1)^2 - 2(2x^2 - 1) = 4x^2 + 4x + 1 - 4x^2 + 2 = 4x + 3
You just add them together. First, you give them all the same denominator. So 2 3/4 goes to 2 6/8 and 1 1/2 goes to 1 4/8. 1 4/8 + 2 6/8 + 7/8 = 3 17/8. 3 17/8 simplified = 5 1/8. So 5 1/8 inches
Answer:
None of these answers are correct but if you meant 3x²-8x+5 then the answer would be D. (3x – 5)(x - 1)
Step-by-step explanation:
3 x 2 - 8x + 5 = 6 - 8x+5
6 - 8x + 5 = 11 - 8x
A. (3x - 1)(x + 5) = 3x²-1x+15x-5 = 3x²+14x-5
B. (3x + 5)(x - 1) = 3x²-3x+5x-5 = 3x²+2x-5
C. (3x – 1)(– 5) = -15x-5
D. (3x – 5)(x - 1) = 3x²-3x-5x+5 = 3x²-8x+5
So none of these answers are correct but if you meant 3x²-8x+5 then the answer would be D. (3x – 5)(x - 1)
The answer is 3 you just divide 24 by 8
