ExplanationSubtract 7 from both sides: x/4 = 5. Multiply by 4: x = 20.
$48
$50
$52
$60
ExplanationIf the price is 20% off, $40 represents 80% of the original. 40 / 0.8 = 50.

144 cm²
154 cm²
164 cm²
ExplanationArea = pi * r^2 = (22/7) * 7 * 7 = 22 * 7 = 154.
3x + 7y
7x + 7y
3x - y
3x + y
ExplanationGroup like terms: (5x - 2x) + (3y + 4y) = 3x + 7y.
3
4
5
6
ExplanationSubtracting 5 from both sides gives 3x = 15. Dividing by 3 gives x = 5.
20
25
30
35
Explanation0.15 multiplied by 200 equals 30.
2^5
2^6
4^5
4^6
ExplanationWhen multiplying terms with the same base, add the exponents: 3 + 2 = 5.
8 cm
10 cm
14 cm
28 cm
ExplanationPerimeter = 2(L + W). 40 = 2(12 + W) -> 20 = 12 + W -> W = 8.
7

ExplanationThe number of elements in a matrix of order m x n is the product m * n. Here, 3 * 4 = 12.
-cos(x)
cos(x)
tan(x)
-sin(x)
ExplanationThe standard derivative of the sine function is the cosine function.
x^2 - 5x + 6 = 0
x^2 + 5x + 6 = 0
x^2 - 6x + 5 = 0
x^2 + 6x + 5 = 0
ExplanationA quadratic equation can be written as x^2 - (sum of roots)x + (product of roots) = 0.
4

ExplanationSince 2^5 = 32, log_2(32) is equal to 5.
3/4
-3/4
4/3
-4/3
ExplanationRearranging the equation to y = mx + c gives 4y = 3x + 7, or y = (3/4)x + 7/4. The slope m is 3/4.
12

ExplanationThe number of arrangements is 4! = 4 x 3 x 2 x 1 = 24.
0
1
2
0.5
Explanationsin(90) = 1 and cos(0) = 1. Therefore, 1 + 1 = 2.
0

-1
2
ExplanationThe determinant of an identity matrix of any size is always 1.
4
5
6
7
ExplanationSubstitute 1 for x: 1^2 + 3(1) + 2 = 1 + 3 + 2 = 6.
90
180
270
360
ExplanationA full rotation around a point corresponds to 360 degrees.
5
7
13
10
ExplanationFirst, calculate f(1) = 2(1) + 3 = 5. Then, calculate f(5) = 2(5) + 3 = 13.
cos(x)
-cos(x)
sin(x)
-sin(x)
ExplanationThe standard derivative of the sine function is the cosine function.
1.5
2
2.5
Infinity
ExplanationThe sum S = a / (1 - r) = 1 / (1 - 0.5) = 1 / 0.5 = 2.
5
8
12
20
ExplanationUsing log rules, log(2x) = log(10), therefore 2x = 10, so x = 5.
3
-3/2
2/3
-3
ExplanationConverting to slope-intercept form y = mx + c, 2y = -3x + 6, so y = -1.5x + 3. The slope is -1.5 or -3/2.
44
154
49
110
ExplanationArea = pi * r^2. Using 22/7 * 7 * 7 = 22 * 7 = 154.
2
x^2 + C
2x^2 + C
x + C
ExplanationThe integral of x^n is x^(n+1)/(n+1). For x^1, it becomes x^2/2. Multiplying by 2 results in x^2.

ExplanationTotal letters = 5, with P repeating twice. Arrangement = 5! / 2! = 120 / 2 = 60.
Equilateral
Scalene
Right-angled isosceles
Obtuse
ExplanationThe sum of angles is 180. 180 - (45+45) = 90. Since two angles are equal, it is isosceles and contains a 90-degree angle.
