Wrong answer I’ll report

z = 27

Step-by-step explanation:

Given that z² is proportional to x³ then the equation relating them is

z² = kx³ ← k is the constant of proportion

To find k use the condition z = 8 when x = 4, thus

8² = k × 4³

64 = 64k ( divide both sides by 64 )

k = 1

z² = x³ ← equation of proportion

When x = 9, then

z² = 9³ = 729 ( take the square root of both sides )

z = = 27

step-by-step explanation:

because i said it is

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
