6. Pete's Painting charges $25 per room to paint, plus an additional $0.50 per square
foot that they paint. If they charged me
$201 to paint my kitchen, how many square
feet did they paint?
A. 201 + 0.50x = 25
B. 25x + 0.50 = 201
C. 201x + 25 = 0.50
D. 0.50x + 25 = 201

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

hi how are you doing today? if you ever need just tell me

step-by-step explanation:

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
