If the side of a square is of length (x + 5), what is its area?
-
X^2 - 10x + 25
-
X^2 - 25
-
X^2 + 10x + 25
-
X^2 + 25
Correct Answer
A. X^2 + 10x + 25Explanation
The area of a square is equal to the side length squared. In this case, the side length is (x + 5), so the area of the square is (x + 5)^2. Expanding this expression gives us x^2 + 10x + 25. Therefore, the correct answer is x^2 + 10x + 25.Rate this question:

If f(x) = 1/(x - 1) what is f(0)?
-
1
-
0
-
-1
-
Undefined
Correct Answer
A. -1Explanation
The function f(x) is defined as 1/(x-1). To find f(0), we substitute 0 into the function for x. Therefore, f(0) = 1/(0-1) = 1/(-1) = -1.Rate this question:

What is the graph of y = 7x - 1?
-
A Line
-
A Circle
-
A Parabola
-
An Ellipse
Correct Answer
A. A LineExplanation
The equation y = 7x - 1 represents a linear function, where the graph is a straight line. The coefficient of x is 7, indicating that for every increase of 1 in x, y will increase by 7. The constant term -1 indicates that the line will intersect the y-axis at -1. Therefore, the graph of y = 7x - 1 is a line.Rate this question:

What value of y makes y/(-10) = 100 a true statement?
-
100
-
-1000
-
-100
-
900
Correct Answer
A. -1000Explanation
To find the value of y that makes the equation true, we can solve for y by multiplying both sides of the equation by -10. This gives us y = 100 * -10 = -1000. Therefore, the value of y that makes the equation true is -1000.Rate this question:

-
1.6
-
6.1
-
0.1666
Correct Answer
A. 0.1666Explanation
The correct answer is 0.1666 because when we divide 1 by 6, we get a repeating decimal of 0.1666.Rate this question:

What values of x make (2x - 3)(3x + 1) = 0 a true statement?
-
-3/2 And -1/3
-
-3/2 And 1/3
-
3/2 And 1/3
-
3/2 And -1/3
Correct Answer
A. 3/2 And -1/3Explanation
To find the values of x that make the given statement true, we need to solve the equation (2x - 3)(3x + 1) = 0. This equation will be true if either of the factors equals zero. Setting 2x - 3 = 0, we can solve for x to find x = 3/2. Setting 3x + 1 = 0, we can solve for x to find x = -1/3. Therefore, the values of x that make the statement true are 3/2 and -1/3.Rate this question:

What is x^3 - x in factored form?
-
X(x + 1)(x + 1)
-
X(x - 1)(x - 1)
-
(x + 1)(x - 1)
-
X(x - 1)(x + 1)
Correct Answer
A. X(x - 1)(x + 1)Explanation
The given expression, x^3 - x, can be factored as x(x - 1)(x + 1). This can be determined by looking for common factors and using the distributive property. The expression can be rewritten as x(x^2 - 1), and then further factored as x(x - 1)(x + 1) by recognizing the difference of squares pattern.Rate this question:

What is the area of a trapezoid that has bases of 10 feet and 14 feet and a height of 8 feet?
-
96 Square Feet
-
144 Square Feet
-
48 Square Feet
-
192 Square Feet
Correct Answer
A. 96 Square FeetExplanation
The area of a trapezoid is calculated by multiplying the average of the lengths of the bases by the height. In this case, the average of the lengths of the bases is (10 + 14) / 2 = 12 feet. Multiplying this by the height of 8 feet gives us an area of 12 * 8 = 96 square feet.Rate this question:

What is the x-intercept of 4x + 2y = -8?
-
(2, 0)
-
(-2, 0)
-
(0, 2)
-
(0, -2)
Correct Answer
A. (-2, 0)Explanation
The x-intercept of a linear equation represents the point where the line crosses the x-axis. To find the x-intercept, we set y = 0 and solve for x. In this equation, if we substitute y = 0, we get 4x + 2(0) = -8, which simplifies to 4x = -8 and x = -2. Therefore, the x-intercept is (-2, 0).Rate this question:

Correct Answer
A. 2Explanation
When x is equal to 1, the equation y = 2^x can be simplified as y = 2^1, which is equal to 2. Therefore, the value of y is 2 when x is 1.Rate this question:

How much interest is earned if $2500 is invested for 25 years at 8% simple interest?
-
500
-
50000
-
2500
-
5000
Correct Answer
A. 5000Explanation
If $2500 is invested for 25 years at 8% simple interest, the interest earned can be calculated using the formula: Interest = Principal * Rate * Time. Plugging in the values, we get: Interest = $2500 * 0.08 * 25 = $5000. Therefore, the correct answer is 5000.Rate this question:

If x = -4 and y = 5, what is (x^4)*(y^2)?
-
-6400
-
6400
-

-
-1280
Correct Answer
A. 6400Explanation
When we substitute the given values of x = -4 and y = 5 into the expression (x^4)*(y^2), we get (-4^4)*(5^2). Simplifying this, we have (256)*(25) which equals 6400. Therefore, the correct answer is 6400.Rate this question:

What is 5(4x - 1) + 9x when simplified?
-
11x - 1
-
29x - 5
-
29x - 1
-
11x - 5
Correct Answer
A. 29x - 5Explanation
To simplify the expression 5(4x - 1) + 9x, we need to distribute the 5 to both terms inside the parentheses. This gives us 20x - 5 + 9x. Combining like terms, we get 29x - 5. Therefore, the correct answer is 29x - 5.Rate this question:
