Answer:
Step-by-step explanation:

Comparing this to the form a+b√5, we see that ...
a = 3/2
b = -1/2
Answer:
I cant answer this question since there is no table or graph
Answer:
9 : 1
Step-by-step explanation:
given a linear ratio = a : b, then the corresponding area ratio is
a² : b²
Here the linear ratio of their edges = 3 : 1, hence
ratio of surface areas = 3² : 1² = 9 : 1
28/7= 4
If there’s 4 people that wear glasses and 3/4 are males then it’s 3.
Each rug is 1/8 of the floor space. So, 4 rugs would cover half of the floor space. Multiply, then reduce.
4(1/8)=4/8 or 1/2
