The widths of two similar rectangles are 10 cm and 15 cm. what is the ratio of the perimeters? of the areas? a. 3 : 4 and 9 : 16 b. 3 : 4 and 4 : 9 c. 2 : 3 and 9 : 16 d. 2 : 3 and 4 : 9

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
