Aregular pentagon had a perimeter of 25m and an area of 43.75m2 find the perimeter of a similar pentagon whth an area of 175m2

50 cm

Step-by-step explanation:

Since the figures are similar then

linear ratios = a : b

area ratios = a² : b²

Here the ratio of areas = 43.75 : 175 = 1 : 4, thus

linear ratios = 1 : 2

The larger pentagon has a perimeter = 2 × 25 = 50 cm

f(x) = y

f(-3) = -5

step-by-step explanation:

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
