4. Two triangles are similar. The corresponding sides have a ratio of 3:5. If the smaller triangle has a
side length of 18 centimeters, what is the measurement of the corresponding side of the larger
triangle?

i think that you should ask google for the answer to that problem because if we don't know it google does

the answer is 48m^2!

step-by-step explanation:

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,
