1. Mathematical Reasoning

Question 1:
What is the value of xxx in the equation 2x+5=172x + 5 = 172x+5=17?
A) 6
B) 7
C) 5
D) 3

Answer: B) 6
Explanation: To solve for xxx, subtract 5 from both sides of the equation:
2x=17−52x = 17 – 52x=17−5
2x=122x = 122x=12
Now, divide both sides by 2:
x=122=6x = \frac{12}{2} = 6x=212​=6.

Question 2:
Which of the following represents the slope of the line given by the equation y=3x+4y = 3x + 4y=3x+4?
A) 4
B) 3
C) 1
D) -3

Answer: B) 3
Explanation: In the slope-intercept form of a linear equation, y=mx+by = mx + by=mx+b, mmm represents the slope. Here, m=3m = 3m=3, so the slope of the line is 3.

Question 3:
What is the perimeter of a rectangle with length 8 meters and width 5 meters?
A) 13 meters
B) 16 meters
C) 26 meters
D) 40 meters

Explanation: The perimeter of a rectangle is given by the formula:
P=2×(length+width)P = 2 \times (length + width)P=2×(length+width)
P=2×(8+5)=2×13=26P = 2 \times (8 + 5) = 2 \times 13 = 26P=2×(8+5)=2×13=26 meters.
