draw a model to represent the polynomial x^2+2x+4

math ~dont know all but check some~ pls help!!!

  1. Draw a model to represent the polynomial x2 + 2x + 4. (1 point)
    1 big square, 1 tall rectangle, 4 little sqaures
    1 big square, 2 tall rectangles, 4 little sqaures in the shape of an “L”
    2 big sqaures, 4 little squares
    none of these
  2. Simplify the polynomial.
    –3f2 + 4f – 3 + 8f2 + 7f + 1
    (1 point)
    5f2 – 11f + 2
    11f2 + 11f + 2
    5f2 + 11f – 2
    –5f2 + 11f – 2
  3. Add or subtract.
    (2×2 + 6x + 1) + (–7×2 + 2x – 3) (1 point)
    5×2 – 4x – 2
    –5×2 + 8x – 2
    5×2 – 8x + 2
    –9×2 – 8x + 2
  4. (3×2 – 7x – 4) – (6×2 – 6x + 1) (1 point)
    –3x^2 – x –5
    –3x^2 –13x + 5
    9x^2 – x + 5
    3x^2 – 13x – 5
  5. Write the perimeter of the figure as a polynomial. Simplify. (1 point)

the shape is a trapizoid
top: 2x
bottom: 3x
left side: 4x + 1
right side: 4x + 1

13x + 2
13x + 1
9x + 1
9x + 2

  1. The area of room A is (5x^2 – 7x – 6) ft^2. Room B has an area of (8x^2 + 6x – 1) ft^2. If room A is the larger room, how much greater is the area of room A than the area of room B? (1 point)
    –3x^2 – x – 7*
    13x^2 – 13x – 7
    –3x^2 – 13x – 5
    3x^2 – x – 5
  2. In the expression –7x – 5×2 + 5, what is the coefficient of x? (1 point)
    7
    5
    –5
    –7*
  3. Write the expression using a single exponent. (1 point)
    2^2 • 2^8
    4^10
    2^10*
    4^16
    2^16
  4. Write the expression using scientific notation. (1 point)
    (2.5 • 104)(4 • 103)
    10 • 10^7*
    10 • 10^8
    1 • 10^8
    10• 10^12

* is my answer
so sorry that i don’t know the first few:(
and sorry if the first one is confusing
but pls help asap!

1

x^2+2x+4 can be written as
x^2 + x(2) + 4*1^2
I think that the best choice would be
1 big square, 1 tall rectangle, 4 little squares

2

–3f^2 + 4f – 3 + 8f^2 + 7f + 1
just collect terms of the same power
(-3+8)f^2 + (4+7)f + (-3+1)
5f^2 + 11f – 2

3

(2x^2 + 6x + 1) + (–7x^2 + 2x – 3)
(2-7)x^2 + (6+2)x + (1-3)
-5x^2 + 8x – 2

4

(3x^2 – 7x – 4) – (6x^2 – 6x + 1)
(3-6)x^2 + (-7+6)x + (-4-1)
-3x^2 – x – 5

5 just add up the sides

2x+3x+4x+1+4x+1
13x+2

6

(5x^2 – 7x – 6)-(8x^2 + 6x – 1)
(5-8)x^2 + (-7-6)x + (-6+1)
-3x^2 – 13x – 5

7 ok

8 ok

9 the number must be less than 10, so instead of 10*10^7 you want 1 * 10^8.
