Answer:

P = 122 | A = 930
P = 116 | A = 616
P = 128 | A = 1008

<h3>Solve(perimeter) ➕</h3>

2 · (30 + 31) = 122
2 · (14 + 44) = 116
2 · (28 + 36) = 128

$\sf Formula$

P = 2 × ( $l$ + $w$ )

<h3>Solve(area) ❎</h3>

31 · 30 = 930
44 · 14 = 616
36 · 28 = 1008

$\sf Formula$

A = $w$ × $l$

Answer:
(a)

Area: 930 meters(m)

Perimeter: 122 meters(m)

(b)

Area: 616 centimeters(cm)

Perimeter: 116 centimeters(cm)

(c)

Area: 1008 millimeters(mm)

Perimeter: 128 millimeters(mm)

Explanation:

Area = length x width

Perimeter = length+width+length+width

Area for (a) is then 31 times 30 = 930
Area for (b) is then 44 times 14 = 616
Area for (c) is then 36 times 28 = 1008

Perimeter for (a) is 31+30+31+30=122

Perimeter for (b) is 44+14+44+14=116

Perimeter for (c) is 36+28+36+28=128

Equality Properties

Step-by-step explanation:

Step 1: Define equation

3(x - 2) = 2(x + 1)

Step 2: Solve for x

Distribute: 3x - 6 = 2x + 2
Subtract 2x on both sides: x - 6 = 2
Add 6 to both sides: x = 8

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Substitute in x: 3(8 - 2) = 2(8 + 1)
Subtract/Add: 3(6) = 2(9)
Multiply: 18 = 18

Here we see that 18 does indeed equal 18.

∴ x = 8 is a solution to the equation.

Prove the following identity true. Show work.

yulyashka [42]

Answer:

The Pythagorean identity states that

$\sin^2 t + \cos^2 t = 1$

Using that we can rewrite the left denominator as:

$1 - \sin^2 t$

Which can be factored as

$(1 - \sin t)(1+ \sin t)$

The numerator we can expand as:

$(1 - \sin t)(1 - \sin t)$

On the right hand side, let's multply numerator and denominator with (1 - sin t):

The total formula then becomes:

$\dfrac{(1-\sin t)(1-\sin t)}{(1 - \sin t)(1 + \sin t)} = \dfrac{(1-\sin t)(1 - \sin t)}{(1+\sin t)(1 - \sin t)}$

There you go... left and right are equal.
