Answer:
what's the question???
Step-by-step explanation:
Well for example if you wanted it to be 60 sq meters then you could do 60/3 which is 20 then the length could be 40 and the width could be 20
Answer:
D
Step-by-step explanation:
Subtract the exponents
W=kxp
where
k is the constant of proportionality given by:
k=w/xp
<span> If w=78 when x=2 and p=10 then
</span>k=78/(2*10)
k=3.9
thus the formula is:
w=3.9xp
b] <span>find x when w=858 and p=5.5
plugging the values in the formula we get:
858=3.9</span>×5.5×x
hence
x=858/(3.9×5.5)
x=358/21.45
x=16.69
