The answer is 6
I got it wrong on the test because I picked 7 automatically my mind thought of 7x3 but it's the wrong math
Here, we are required to find the vertical and horizontal intercepts for r⁴ + s² − r s = 16.
The vertical and horizontal intercepts are s = ±4 and r = ±2 respectively.
According to the question;
- the r-axis is the horizontal axis.
- the s-axis is the vertical axis.
Therefore, to get the horizontal intercepts, r we set the vertical axis, s to zero(0).
- i.e s = 0
- the equation r⁴ + s² − r s = 16, then becomes;
- r⁴ = 16
- Therefore, r = ±2.
Also, to to get the vertical intercepts, s we set the horizontal axis, r to zero(0).
- i.e r = 0.
- the equation r⁴ + s² − r s = 16, then becomes;
- s² = 16.
- Therefore, s = ±4.
Therefore, the vertical and horizontal intercepts are s = ±4 and r = ±2 respectively.

Answer:
length = 60 cm
Step-by-step explanation:
ratio of width : length = 3 : 4 = 3x : 4x
perimeter = (2 × width ) + (2 × length) = 6x +8x = 14x
now perimeter = 210, hence
14x = 210 ( divide both sides by 14 )
x = 15
hence length = 4 × 15 = 60 cm
The answer to this question is choice option letter C
