Answer:
Width = 9 cm, length = 14 cm
Step-by-step explanation:
Width = w; Length = L
2(W+L) = 46, W+L = 23, W= 23-L
W*L = 126, (23-L)*L = 126
W = 9, L = 14
Answer:
The combined weight of all the kittens is 5 pounds.
Step-by-step explanation:
The distribution of kittens according to their weights is as follows:
Weight (W) No. of Kittens (f)
pounds 2
pounds 3
pounds 3
pounds 3
Compute the combined weight of all kittens as follows:
Total weight = ∑ (W × f)
Thus, the combined weight of all the kittens is 5 pounds.
Xy = 450
y = x/2 => x=2y substituted inside first equation will get 2y*y=450 => y^2 = 225
y=15 because 15*15=225
x=2y so x=2*15 = 30
x=30
y=15
