Given that y = h^xm such that h and m are constants. Also, given that y = 24 when x = 2 and y = 375 when x = 5. Find the value of h and of m. please help me​

all three statements are true

step-by-step explanation:

a shipping fee of 5% is charged online with every item purchased online

first let's just take each option and calculate them based on this, to see if the answers matched

keith buys a 40 dollar book

40 x 0.05 = 2

therefore there will be a two dollar fee on keith's book

40 + 2 =42

the first statement is true

a chair costs $80

80 x 0.05 = 4

80 + 4 = 84

the second statement is true

george buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

the third statements are true

all three statements are true

(5x-1)^2= (5x)^2-2(5x)×1+(1)^2=25x^2-10x+1
