first clarify the question you can use parenthesis
write the expression then replace q with 2 and compute

- triciaal

based on the answer choices the question is (4 times a number q ) plus 25
4*2 = 8 8 + 25 = 33

2) I don't know what you mean
write the expression properly then let p = 8

- supercait10

hold on

- triciaal

|dw:1441218753454:dw|

- triciaal

all the same process
write the expression then substitute with the value
compute /simplify

think you have the wrong question based on the answer choices

- supercait10

no thats the answers in the quick practice test

- triciaal

did you write the question correctly?

- triciaal

|dw:1441219806079:dw|

- supercait10

yes its \[p = 8, Evaluate 4^{2} \div p.3\]

- supercait10

thats the problem

- triciaal

yes what does it mean?
did you mean p^1/3?

- supercait10

idk its in the practice test

- triciaal

when p = 8 8^.3 =8^1/3 = 2

- supercait10

okay thanks

- supercait10

then can u help me out of the last one

- supercait10

how it is on the test its p.3 thats what the test shows

- triciaal

I had to think yes 3p = 3 times p p.3 = p^.3

- supercait10

okay its fine just help me out of the third one the second doesn't matter

- triciaal

no its not fine if you don't understand!!
I already did the third one

- supercait10

the second one is only worth half a point but still i have to do it the third and the first one are worth three points

- triciaal

next time the second one could cost you 50 points
I think it comes down to understanding how to write see I missed it if it weren't for the choices then I had to "read in math"

- supercait10

nevermind i just failed the test anyways so it doesn't matter at this point it was a timed test and i failed so there is no point on telling me

- triciaal

|dw:1441220648609:dw|

- triciaal

sorry you failed but if the question is not clear then it is different from what is expected and will be a different problem altogether

- supercait10

its fine
