Answer:
Question 8: answer is D
Question 7: answer is B
You can tell which one is bigger because the one with a larger box has a bigger IQR :)
You can tell the minimum is bigger by looking at the numbers on the number line
The second one : f(x) = x+3, x<0
= 3, x>=0
Let the shortest side = X and the longer = 4X
perimeter = (length + width) ×2
30 = (4X + X)×2
30 = 8X + 2X
30 = 10X divide 10 to both sides
3 = X
the longer side = 4X = 4 × 3 = 12 cm
the shortest side = X = 3 cm
area = length × width
area = 3×12 = 36 cm^2
