Answer:
L = 13 m W = 11 m
Step-by-step explanation:
L = W + 2
area = L x W
143 = (W+2) * W
143 = W^2 + 2w
W^2 + 2W - 143 = 0
Use Quadratic Formula (a = 1 b = 2 c = - 143)
to find W = 11 m then L = 13
Answer:
B
Step-by-step explanation:
They both equal 121

- Correlation coefficient measures the strength of that relationship.
- Calculating a Pearson correlation coefficient requires the assumption that the relationship between the two variables is linear.
- The relationship between two variables is generally considered strong when their r value is larger than 0.7.
