I believe it is 3x+21 but i could be wrong :/ my explaination is -3 • -X would be +3x because it was distributed and -3 • -7 would be +21
Answer:
it is false because, in the equation 84 does not equal 84.
Step-by-step explanation:
Hope I could help, if you need the equation let me know! :)
V=(1/3)hpir^2
lets say this is original, undoubled volume
so o=v=(1/3)hpir^2
so for new volume, or n, that is r to 2r, doubled radius
n=(1/3)hpi(2r)^2
n=(1/3)hpi4r^2
n=4((1/3)hpir^2)
remmember that o=(1/3)hpir^2
n=4(o)
it is 4 times the old one
$33,075 = 0.05S + S
$33,075 = 1.05S
$33,075/1.05 = 1.05S/1.05
S= $31,500
Check
$31,500 * 5% = $1575 + $31,500 =$33,075
