# 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
(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

so sorry that i don’t know the first few:(
and sorry if the first one is confusing
but pls help asap!
help much apprectiated, thank you:)

# 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

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

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