We need a rock garden with a perimeter of 12 feet and an area of 8 square feet

4n=2m

ratio of m to n: 2/4 = 1/2

answer

a. 1/2

option c is correct.

step-by-step explanation:

the rule regarding the sides of triangle is:

(length of longest side)^2 = square of sum of other two sides.

the sides given are:

6, 10 and 8.

applying the rule we will get:

(10)^2 = (6)^2 + (8)^2

100 = 36+64

100 = 100

so, her answer is incorrect.

no, she should have added 6^2 and 8^2 and compared that to 10^2.

so, option c is correct.

given expression is

we have radical  

we need to select an option that has same radical

(a)  

this expression has cube root instead of square root . so it is not a like radical.

(b)

y is included inside the radical. so it is not a like radical.

(c)

this expression has cube root instead of square root . so it is not a like radical.

(d)

5 is inside the radical square root. so it is   a like radical.
