Estimate the perimeter and the area of the shaded figure


Show how u got it please.

Answers

Answer:

8(1 +√2)

Step-by-step explanation:

The perimeter is the sum of the sides of the figure

Taking 1 square box as 1 unit

Get the slant side using the pythagoras theorem;

l² = 2² + 2²

l² = 4 + 4

l² = 8

l =√8

Perimeter = 4(√8) + 4 + 4

Perimeter = 8 + 4√8

Perimeter = 8 + 4*2√2

Perimeter = 8 + 8√2

Perimeter = 8(1 +√2)

hence the perimeter of the shape is 8(1 +√2)

Answers

Answer: x = 3 - sqrt 17 / 2 , x = 3 + sqrt 17 / 2

Step-by-step explanation:

2x^2 = 4 + 6x

divide both sides by 2

x^2 = 2 + 3x

move expression to the left

x^2 - 2 - 3x = 0

reorder the terms

x^2 - 3x - 2 = 0

use the quadratic formula

x = - (-3) +- sqrt (-3)^2 - 4 x (-2) / 2 x 1

calculate

x = 3 +- sqrt 17 / 2

answer

x = 3 - sqrt 17 / 2 , x = 3 + sqrt 17 / 2

What is expression ?

Expressions is a finite combination of symbols that is well-formed according to rules that depend on the context.

Part A ;

We have,

[tex]8[/tex] more than [tex]5[/tex] times a number

Now,

Let a number [tex]=x[/tex]

So,

According to the question,

We get, [tex](8+5x)[/tex]

So, this is the algebraic expression .

Part B ;

We have,

[tex]4(n + 6)[/tex]

So,

According to the question,

[tex]4(n + 6)[/tex] will be written as four times the sum of a number and six.

So, this is the verbal expression .

Hence, we can say that the algebraic expression for [tex]8[/tex] more than [tex]5[/tex] times a number will be [tex](8+5x)[/tex] and the verbal expression for [tex]4(n + 6)[/tex] will be four times the sum of a number and six.
