Answer:
What are the options
Step-by-step explanation:
IT IS C BECAUSE IT IS SAYING IT WAS 43 AND IS NOW DROPPING BY -3
Question 1
Simplify the following expression: (5x2 + 3x + 4) − (2x2 − 6x + 3). If
the final answer is written in the form Ax2 + Bx + C, what is the value
of B?
Solution:
5x^2 + 3x + 4 - 2x^2 + 6x - 3 = 3x^2 + 9x + 1
Then, B = 9
Question 2
Simplify: (3x2 − 2) + (2x2 − 6x + 3)
5x2 − 6x + 1
5x2 − 6x − 1
x2− 6x + 1
5x2 − 8x + 3
Solution:
3x^2 - 2 + 2x^2 - 6x + 3 = 5x^2 - 6x + 1
Question 3
A sports company conducted a road test of a new model of a geared bike.
The test rider cycled (3x - 2) miles on a flat road, (x2 - 5) miles
uphill, and (2x + 7) miles downhill. Which simplified expression is
equivalent to the total distance, in miles, for which the bike was
tested?
x2 - x
x2 + 5x
x2 − x + 14
x2 + 5x + 14
(3x - 2) + (x2 - 5) + (2x + 7) = 3x - 2 + x^2 - 5 +2x + 7 = x^2 + 5x
Question 4
Simplify: (4x − 6) − (5x + 1)
x + 7
−x + 7
x − 7
−x − 7
(4x − 6) − (5x + 1) = 4x - 6 - 5x - 1 = -x -7
Question 5
Simplify the following expression: (x + 6y) - (3x − 10y). If the final
answer is written in the form Ax + By, what is the value of A?
(x + 6y) - (3x − 10y) = x + 6y - 3x + 10y = -2x + 16y
A = -2
Question 6
Simplify: (3x − 5) + (3x + 6)
6x − 1
1
6x − 11
(3x − 5) + (3x + 6) = 3x - 5 + 3x + 6 = 6x + 1
Answer:
L = 22 ft
Step-by-step explanation:
Let L and W represent the length and width respectively.
L = 4W, or W = L/4. Use W = L/4 because we want to solve for W, not for L.
Area of a rectangle: A = L · W
Here, A = L · L/4 = 121 ft²
Mult. both terms by 4 removes the fraction:
L² = 484
Finding the square root of this result: L = 22
The length of the rect. is 22 ft.
1. Divide the first term of the numerator by the first term of the denominator, and put that in the answer.
2. Multiply the denominator by that answer, put that below the numerator.
3. Subtract to create a new polynomial.
