Step-by-step explanation:

y = 18 + 3x²

- 18 - 18

__________

$\frac{-18 + y}{3} = \frac{3x^2}{3} \\ \\ -6 + \frac{y}{3} = x^2 \\ \\ \sqrt{-6 + \frac{y}{3}} = x$

Put 3/8, 2/5, and 0.38 from least to greatest

Vesnalui [34]

3/8=0.375
2/5=0.4
0.38=0.38

0.375<0.38<0.4

therefore: 3/8,0.38,2/5

*Remember that you can convert fractions to decimals by dividing the numerator by the denominator! This makes it much easier to compare :)

notsponge [240]

A(r)=3.14r^2, when r=5

A(5)=3.14(5^2)

A(5)=3.14(25)

A(5)=78.5 u^2
