Find the perimeter of a square with side lengths 4.7cm

If the side length is 4.7cm, since it is a square then we multiply the side length by 4. So 4.7cm X 4= 18.8

So to find the perimeter of a square, we must add all of the sides together.
We know that a square's sides are all equal in length and that a square has 4 sides. So that means we need to add 4.7 four times to get the perimeter.
4.7 + 4.7 + 4.7 + 4.7 = 18.8
So the perimeter of the square is 18.8 cm.
Hope I helped!

The first question: Solve by taking the square root I need help understanding the steps to solve this!

shepuryov [24]

Answer:

see explanation

Step-by-step explanation:

(1)

Given

3(x + 3)² - 1 = - 13 ( add 1 to both sides )

3(x + 3)² = - 12 ( divide both sides by 3 )

(x + 3)² = - 4 ( take the square root of both sides )

x + 3 = ± $\sqrt{-4}$ = ± 2i ( subtract 3 from both sides )

x = - 3 ± 2i ← complex conjugate roots

(2)

Given

3x² - 12x + 27 = 0 ( subtract 27 from both sides )

3x² - 12x = - 27 ( divide through by 3 )

x² - 4x = - 9

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 2)x + 4 = - 9 + 4

(x - 2)² = - 5 ( take the square root of both sides )

x - 2 = ± $\sqrt{-5}$ = ± i $\sqrt{5}$ ( add 2 to both sides )

x = 2 ± i $\sqrt{5}$ ← complex conjugate roots

A ladder leans against the side of a house. The angle of elevation of the ladder is 66 degrees when the bottom of the ladder is

Ierofanga [76]

Answer:

The length of the ladder = 6.5077 ft

Step-by-step explanation:

Given A ladder leans against the side of a house

Given the angle of elevation of the ladder is 66° when the bottom of the ladder is 16 ft from the side of the house

<em>Let 'C' be the point of observation.</em>

Given CA= 16 ft

<em> From right angle triangle</em>

<em> </em> $cos C = \frac{CB}{CA}$

$cos 66 = \frac{x}{16}$

x = 16 × cos 66°

x = 16 × 0.4067

x = 6.5077

<em> x = 6.5 ft</em>

<em>The length of the ladder = 6.5 ft</em>
