Hey, my name is esteban and i'm not really good in maths so here's the problem : A= -2/5 : 3/15 + 2/15 B= 9/2 - 5/2 : 15/8

if you could explain all the calculations it would help me a lot

Thanks-you

step-by-step explanation:

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

he will have 300 because he is really broke and 300 is in his imangine
