x=8
OpenStudy (anonymous):
Nope @Callie
OpenStudy (anonymous):
Hint : I2x-3I=13
IS
2x-3=13 and 2x-3=-13
OpenStudy (anonymous):
2 X 8-3
2X8+16 -3 +13
YES

ok
OpenStudy (anonymous):
hey can you also help me on this one
P = 2w + 2h for w.
i really dont get it
OpenStudy (anonymous):
Take 2h to the left had side and divide both sides by 2
OpenStudy (anonymous):
hand side
OpenStudy (anonymous):
ok then what

do it first and show me what u got
OpenStudy (anonymous):
ok i got 1 for both sides
OpenStudy (anonymous):
what?
OpenStudy (anonymous):
i got 1
OpenStudy (anonymous):
p=2w+2h
p-2h=2w
w=(p-2h)/2

wait so what is p
here are my answers
w = P – 2h
w = P – 2h – 2
w = P - h / two
w = P - 2h / two
OpenStudy (anonymous):
w = P - 2h / two
OpenStudy (anonymous):
right?
OpenStudy (anonymous):
oh ok
OpenStudy (anonymous):
yes that is right
