-
5
-
4
-
1
Correct Answer
A. 1Explanation
The degree of a polynomial is determined by the highest power of the variable in the polynomial. In this case, the polynomial is ax-c, which has a variable raised to the power of 1. Therefore, the degree of the polynomial is 1.Rate this question:

-
Equal
-
Equivalent
-
Disjoint
-
Overlapping
Correct Answer
A. EqualExplanation
If n(A) = n(B), it means that the number of elements in set A is equal to the number of elements in set B. Therefore, A and B are called "Equal" sets.Rate this question:

The difference between the length and breadth of a rectangle is 23 m. if its perimeter is 206 m, its area is
-
1520 square meter
-
2420 square meter
-
2480 square meter
-
2520 square meter
Correct Answer
A. 2520 square meterExplanation
Let's assume that the length of the rectangle is L and the breadth is B. According to the given information, L - B = 23 and the perimeter (P) is 206. The formula for the perimeter of a rectangle is P = 2(L + B). Substituting the given values, we get 206 = 2(L + B). Simplifying this equation, we find that L + B = 103. Now we have a system of equations: L - B = 23 and L + B = 103. Solving this system, we find that L = 63 and B = 40. The area (A) of a rectangle is given by the formula A = L * B. Substituting the values, we get A = 63 * 40 = 2520 square meters.Rate this question:

If each side of a square is halved, the area of the new square is ______ the area of the original square
-
One-ninth
-
Double
-
One-fourth
-
Four times
Correct Answer
A. One-fourthExplanation
When each side of a square is halved, the resulting square has sides that are half the length of the original square. Since the area of a square is calculated by multiplying the length of one side by itself, halving the length of each side would result in the area being one-fourth of the original square. Therefore, the correct answer is one-fourth.Rate this question:
