Answer:
<h2>
The answer is A</h2><h2>A. S = 1/2p - L</h2>
Step-by-step explanation:
Step one:
given the perimeter function
P = 2S + 2L
we are expected in this problem to change the subject of the formula to S
Step two:
firstly, let us isolate the term that has S
2S=P-2L
divide both sides by 2
2S/2= (P-2L)/2
S=P/2-L
S = 1/2p - L
Answer: Donna is wrong. Mean weight is 7.1kg
Step-by-step explanation:
Calculate the mean for the bricks:
4 bricks have a mean weight of 5kg = 4 * 5
5 bricks have a mean weight of 9kg = 5 * 9
1 green brick is 6kg
= (4 * 5 ) + ( 5 * 9) + 6
= 71kg
Mean = 71 / (4 + 5 + 1)
= 7.1 kg
