above guy is right. i donot about this.sorry and thanks.

Answer:

Step-by-step explanation:

1. P = (width + lengh) * 2 = (23 + 10) * 2 = 33 * 2 = 66

  A = width * lengh = 23 * 10 = 230

2. width = 7

 P = (width + lengh) * 2 = ( 7 + 9) * 2 = 16 * 2 = 32

Answer:

4. area= 230cm^2 perimeter= 66cm

5. width= 7m  perimeter= 32m

Step-by-step explanation:

4. a = w*l

23cm*10cm=230cm^2

p= add all sides

23cm+23cm+10cm+10cm=66cm

5. w= a/l

63m^2/9m=7m

p= add all sides

7m+7m+9m+9m=32m

Answer:

24

Step-by-step explanation:

To find how old Mrs. Roberts was when her son was born, we first need to know both of their ages. I'm going to give Mrs. Roberts the variable m and her son the variable s.

Let's turn the two sentences about their ages into equations:

m=Mrs. Roberts and 3s= three times as old as her son

m=3s

m+s is the sum of their ages

m+s=48

Now substitute the first equation into the second one:

m+s=48

(3s)+s=48

4s=48

s=12

The son is 12 years old. Now substitute s into one of the equations to solve for the mother's age:

m=3s

m=3(12)

m=36

Mrs. Roberts is 36. Since they are asking how old she was when her son was born, we will subtract her son's age from her age, since she would be 12 years younger:

36−12=24

Mrs. Roberts was 24 when her son was born.

Answer:

8

Step-by-step explanation:

That little square means the angle between the L shape is 90 degrees.

This means that the two angles must add up to 90 degrees:

(6x+2)+(4x+8)=90

10x+10=90

10x=80

x=8

a right angle is 90 degrees. take both equations and put them together and add like terms.

10x + 10 = 90. subtract 10 from both sides.

10x = 80. divide by 10 on both sides.

x = 8

Answer:

2009cm^2

Step-by-step explanation:

Given data

let the length be L

and the width be w

so

w= x

L=x+8

P= 180cm

P= 2L+2W

180= 2(x+8)+2(x)

180= 2x+16+2x

collect like terms

180= 4x+16

180-16= 4x

164= 4x

x= 164/4

x=41

W= 41cm

L= 41+8

L= 49cm

A= L*W

A=49*41

A=2009cm^2

Hence the area is 2009cm^2

Answer:

x=(5+√73)/2 or x=(5-√73)/2

Step-by-step explanation:

a=1 b=-5 c=-12

x= (-b+/-√b^2-4ac)/2a

x= (-(-5)+/-√(5)^2-4(1)(-12))/2(1)

x= (5+/-√25-4(-12))/2

x= (5+/-√25+48)/2

x= (5+/-√73)/2

x=(5+√73)/2 or x=(5-√73)/2

The expanded form of this number 570.086 is,

⇒ (5 × 100) + (7 × 10) + (8 × 1/100) + (6 × 1/1000)

The value represented by a digit in a number on the basis of its position in the number is called a Place value.

Given that;

The number is,

⇒ 570.086

Now, We can expand the number as;

⇒ 570.086

⇒ 500 + 70 + 00 + 8/100 + 6/1000

⇒ (5 × 100) + (7 × 10) + (8 × 1/100) + (6 × 1/1000)

Thus, The expanded form is,

⇒ (5 × 100) + (7 × 10) + (8 × 1/100) + (6 × 1/1000)

Answer:

C

Step-by-step explanation:

(2,-5) move up three steps is (2, -2). if you draw it on a paper(and draw lines to connect them), you can see that they form a right triangle. apply a²+b²=c² and you should get 3²+2²=(√13)²

First we need to find the point after the translation of 3 units up.

(2,-5)->(2,-2)

Now we have the point (2,-2) we just need to use the difference formula to find the distance between this point and (5,0)

Distance=[tex]\sqrt{(5-2)^2+(0-(-2))^2}[/tex]

Now we need to simplify/solve this expression

=[tex]\sqrt{3^2+2^2}[/tex]

=[tex]\sqrt13[/tex]

Therefore the answer is C!
