Question

A=3,b=1,2a-3(2-b) pls answer asap

Answer 1

Answer: can u pls mark me brainliest pls

1. (x+1)²-3(x+2)

   = x² + 2x + 1 - 3x - 6

   = x² - x - 5  (the answer is B)

2. (5x³y⁻³)(-6x⁴y)

    = -30x³⁺⁴y⁻³⁺¹

    = -30x⁷y⁻²

    = -30x⁷/y²  (the answer is D)

3. [(8+x)/2 - (x+3)/3=4]*6

   3(8+x) - 2(x+3) = 24

   24 + 3x - 2x - 6 = 24

   x = 24 - 24 +6

   x=6  (the answer is B)

4. x²-3x-8=x+4

   x² - 3x - x -8 - 4 = 0

   x² - 4x -12 = 0

   (x-6)(x+2) = 0

   x = 6 and -2  ( the answer is D)

5. To complete the squares, divide the middle term by two and find its square. That would be (8/2)² = 16. The answer is D.
