Answer:

The perimeter is 22.

Step-by-step explanation:

The perimeter formula (it sometimes varies) is 2(b+h)

b being base (in this example, 6)

h being height (in this example, 5)

So now, with substitution, we are left with:

2(6+5)

Which simplifies down to:

2(11)

Mondo correctly finds the closest benchmarks for three numbers.

Answer:

From greatest to least, the order is:

$3.8,\ 3\frac{4}{9},\ 3\frac{6}{25}$

Step-by-step explanation:

Given

$Closest\ Benchmark \to Number$

$3\frac{6}{25} \to 3$

$3\frac{4}{9} \to 4$

Required

Order $3\frac{6}{25}, 3.8, 3\frac{4}{9}$ from greatest to least

From the given parameters, we have:

$3\frac{6}{25} \to 3$

$3\frac{4}{9} \to 4$

This implies that:

$3\frac{4}{9}\ >\ 3\frac{6}{25}$ --- we know this from the nearest benchmark

Convert $3\frac{4}{9}$ to decimal

$3\frac{4}{9} = 3.44$

By comparison;

$3.8 >\ 3\frac{4}{9}$

Hence, the list is:

$3.8,\ 3\frac{4}{9},\ 3\frac{6}{25}$

Simplify the expression

Stolb23 [73]

Answer:

A. ${x}^{3} - x - \frac{6}{2x + 3}$

Step-by-step explanation:

$\frac{2 {x}^{4} + 3 {x}^{3} - 2 {x}^{2} - 3x - 6}{2x + 3} \\ \\ = \frac{(2 {x}^{4} + 3 {x}^{3} ) - (2 {x}^{2} + 3x) - 6}{2x + 3} \\ \\ = \frac{ {x}^{3} (2 {x} + 3 ) - x(2 {x} + 3) - 6}{2x + 3} \\ \\ = \frac{ {x}^{3} (2x + 3)}{2x + 3} - \frac{x(2x + 3)}{2x + 3} - \frac{6}{2x + 3} \\ \\ \purple { \bold{= {x}^{3} - x - \frac{6}{2x + 3} }}$
