1
Correct Answer
B. 16Explanation
The expression 4^2 represents 4 raised to the power of 2. In mathematical terms, this is referred to as "four squared." When you square a number, you multiply the number by itself.
So, 4^2 is calculated as follows:
4×4=16
Thus, 4^2 equals 16.Rate this question:

- E.
4
Correct Answer
C. 2Explanation
To find the value of
𝑥 in the equation 2x−4=0, you can follow these steps:
Add 4 to both sides of the equation to isolate the term with
x on one side:
2x−4+4=0+4
2x=4
Divide both sides by 2 to solve for 𝑥
2x / 2 = 4/2
x=2
Thus, the value of
x is 2.Rate this question:

Correct Answer
A. 6Explanation
To find the value of ( y ) when ( x = -1 ) using the given formula, we can substitute ( x ) into the equation shown on the graph:
[ y = (x-1)^2 + 2 ]
Substituting ( x = -1 ):
[ y = (-1-1)^2 + 2 = (-2)^2 + 2 = 4 + 2 = 6 ]
Therefore, when ( x = -1 ), the value of ( y ) is ( 6 ).Rate this question:

What is the slope of a line containing the points (3,2) and (-1,0).
- A.
-3/2
- B.
-1
- C.
2/1
- D.
1/2
Correct Answer
D. 1/2Explanation
The slope of a line can be found using the formula (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of two points on the line. In this case, the coordinates are (3,2) and (-1,0). Plugging these values into the formula, we get (0 - 2) / (-1 - 3) = -2 / -4 = 1/2. Therefore, the slope of the line is 1/2.Rate this question:

Correct Answer
B. 5 1/2Explanation
The given expression involves adding two fractions with a common denominator of 2. When we add 4/2 and 7/2, we get a sum of 11/2. However, 11/2 can be simplified to the mixed number 5 1/2. Therefore, the correct answer is 5 1/2.Rate this question:

Which term describes a polynomial with two terms?
- A.
Monomial
- B.
Binomial
- C.
Trinomial
- D.
Polynomial
Correct Answer
B. BinomialExplanation
In algebra, a polynomial with two terms is called a binomial. Each term is referred to as a monomial, and a binomial consists of two such monomials. Common examples include expressions like x+y and 3x2−2x. The prefix "bi-" indicates two, aligning with the number of terms.Rate this question:

3
Correct Answer
E. 3Explanation
To find the value of ( a ) using the Pythagorean theorem when ( b = 4 ) and ( c = 5 ), the formula used is:
[ a^2 + b^2 = c^2 ]
Given ( b = 4 ) and ( c = 5 ), substitute these values into the formula:
[ a^2 + 4^2 = 5^2 ]
[ a^2 + 16 = 25 ]
Now, solve for ( a^2 ):
[ a^2 = 25 - 16 ]
[ a^2 = 9 ]
Taking the square root of both sides gives:
[ a = √{9} ]
[ a = 3 ]
Thus, when ( b = 4 ) and ( c = 5 ), the value of ( a ) is ( 3 ).Rate this question:

Find the value of x in this equation: x + 2(x + 7) = 14x– 7.
- A.
3/2
- B.
21/11
- C.
11/7
- D.
2/5
Correct Answer
B. 21/11Explanation
To find the value of x in the equation, we first distribute the 2 to the terms inside the parentheses: x + 2x + 14 = 14x - 7. Then, we combine like terms: 3x + 14 = 14x - 7. Next, we isolate the variable terms on one side and the constant terms on the other side: 14 + 7 = 14x - 3x. Simplifying further, we have 21 = 11x. Finally, we divide both sides by 11 to solve for x, resulting in x = 21/11.Rate this question:

Correct Answer
A. 6Explanation
To find the value of z, we need to solve the equation. First, we distribute the 5 and 3 to the terms inside the parentheses: 5z + 5 = 3z + 6 + 11. Then, we combine like terms: 5z + 5 = 3z + 17. Next, we subtract 3z from both sides: 2z + 5 = 17. Finally, we subtract 5 from both sides: 2z = 12. Dividing both sides by 2, we find that z = 6.Rate this question:

Correct Answer
C. 10Explanation
To find the value of x in the given equation, we need to simplify the equation by combining like terms and isolating x. First, we can find a common denominator for the fractions by multiplying the first fraction by 7 and the second fraction by 4. This gives us (7(x - 2) - 4(3x + 5)) / 28 = -3. Next, we can distribute the numbers and simplify the equation to get (7x - 14 - 12x - 20) / 28 = -3. Combining like terms, we have (-5x - 34) / 28 = -3. To isolate x, we can cross-multiply and solve for x, which gives us -5x - 34 = -84. Solving for x, we find x = 10.Rate this question:

0
Correct Answer
C. -6Explanation
Start by isolating the variable q on one side of the equation. To do this, you need to move all terms with q to one side and constants to the other side.
12q - 14q = 2 + 10
-2q = 12
Now, divide both sides by -2 to solve for q:
(-2q) / (-2) = 12 / (-2)
q = -6
So, the value of q is q = -6.Rate this question:

Correct Answer
B. 4Explanation
To solve for x, you need to isolate x on one side of the equation. Start by subtracting 3 from both sides to eliminate the constant term on the left side:
2x+3−3=11−3
This simplifies to:
2x=8
Next, divide both sides by 2 to solve for
2x= 8/2

[a(b+c)=ab+ac]
- B.
[a+b=b+a]
- C.
[a(bc)=(ab)c]
- D.
[a(b−c)=ab−ac]
Correct Answer
A. [a(b+c)=ab+ac]Explanation
The distributive property allows you to multiply a sum by multiplying each addend separately and then adding the results. It is generally expressed as:
a(b+c)=ab+ac. This property is essential for simplifying expressions and solving equations where a term is distributed across terms within parentheses.Rate this question:
