Answer:

  16

Step-by-step explanation:

Put the numbers where the variables are and evaluate:

  F(3) = 2(3)^2 +1 = 19

  G(4) = 2(4) -1 = 7

  H(5) = 5

Then the desired sum is ...

  F(3) +G(4) -2H(5) = 19 +7 -2(5) = 16

For multiplying fractions you basically just multiply across so for the green one it would be 1x4=4 so you would have 4 as the numerator for the answer and the bottom is 2x8=16 so that would be the denominator your answer would be 4/16 for the green question

Without using a calculator, order the following expressions from least to greatest.
LekaFEV [45]

Answer:

\displaystyle \large{\frac{11}{3} < \sqrt{17} < \sqrt{20}}

Step-by-step explanation:

( 1 ) 11/3

\displaystyle \large{\frac{11}{3}} can be converted to mixed fractions to \displaystyle \large{3\frac{2}{3}}

Therefore, 11/3 is at least around 3, almost 4. It could be more than 3.5 by approximation but not exactly 4.

( 2 ) √20

\displaystyle \large{\sqrt{20}=\sqrt{5\cdot 4}}\\\displaystyle \large{\sqrt{20}=\sqrt{5\cdot 2\cdot 2}}\\\displaystyle \large{\sqrt{20}=2\sqrt{5}}

We know that \displaystyle \large{\sqrt{4}=2} so \displaystyle \large{\sqrt{5} > \sqrt{4}} which means approximately, \displaystyle \large{\sqrt{20}} can be either at least 4.3 up to 4.4

( 3 ) √17

We know that \displaystyle \large{\sqrt{16} = 4} so \displaystyle \large{\sqrt{17}} can be at least 4.1 up to 4.2, but it’s obvious that the square root of 17 is less than square root of 20 since \displaystyle \large{\sqrt{a} > \sqrt{b}} for a > b

Hence, from least to greatest:

\displaystyle \large{\frac{11}{3} < \sqrt{17} < \sqrt{20}}
