We know that
[area of the painting]=13 in* 17 in-----> 221 in²
if a<span>n artist painting at
$0.30 per --------------> 1 in</span>²
x$--------------> 221 in²
X=221*0.30------> x=$66.30
the answer is
$66.30
Answer:
a^4 - a^3 + a^2 - 2a - (2)/(a + 1)
The answer is x= -10. To get this answer you have to simplify both sides of the equation, distribute, and combine the like terms. The second step is to add 15/2x to both sides. Step 3 is to subtract 72 from both sides, then divide both sides by 3

Answer:
y=-3
Step-by-step explanation:
"varying directly" means there is only a factor between x and y, i.e.:
y = k·x
so k = y/x = -1/3
so if x=9, y = -1/3·9 = -3
