Me sombody will give ! 1. find the product of (x + 3)2. x2 − 9 x2 − 6x + 9 x2 + 6x + 9 x2 + 9 2. find the product of (x + 3)(x − 3). x2 + 6x + 9 x2 − 6x + 9 x2 + 9 x2 − 9 3. find the product of (2x − 5y)2. 4x2 − 20xy + 25y2 4x2 + 25y2 4x2 − 25y2 4x2 + 20xy + 25y 4. find the product of (2x + 5y)2. 4x2 + 25y2 4x2 − 20xy + 25y2 4x2 + 20xy + 25y2 4x2 − 25y2

1)2x+62)x^2-93)4x-10y4)4x+10yi really tried sorry.

1) product of (x+3)2. x2+6x+9 (first we need to square x which is x2, next we multiply x by 3 and by 2 which will be 6x, the final step is to square 3, square of 3 is 2) product of (x+3)(x-3). x2-9. (here we should multiply (x-3) by (x+3). so, let’s take x first, now multiply (x-3) by x= x2-3x, next let’s take 3 from first pair of brackets, 3(x-3)= 3x-9. let’s combine: x2-3x+3x-9. (-3x and 3x cancel out because they eliminate each other) so, the final answer will be x2- 3) product of (2x-5y)2. 4x2-20xy+25y2. (2x squared equals 4x2 because we square coefficients too.then, 2x multiplied by -5y and by 2 equals -20xy, -5y squared is 25y2). 4)product of (2x+5y)2. 4x2+20xy+25y2 ( just as was the previous one but with positive sign for 20xy).

Answer: r=4.5  feetexplanation: radius  r  is half of the diameter  d,⇒r=d2=92=4.5  feetidk i could be wrong
