Answers
The quadrilaterals are similar and are related by a scale factor, taken from
a specific location, that maps the points on one figure to the other.
a. The scale factor that takes Figure 1 to Figure 2, is 3
b. The scale factor that takes Figure 2 to Figure 1 is [tex]\dfrac{1}{3}[/tex]
Reasons:
From the question, we have that Figure 1 is a scaled copy of Figure 2, therefore;
Let ABCD represent Figure 1, we have;
ABCD ~ PQRS
Length of [tex]\overline{AD}[/tex] = √(2² + 3²) = √(13)
Length of [tex]\overline{PS}[/tex] = √(6² + 9²) = √(117) = √(9 × 13) = 3·√(13)
Therefore;
a. The scale factor that takes Figure 1 to Figure 2, SF₁₂, is therefore;
[tex]SF_{12} = \mathbf{\dfrac{\overline{PS}}{\overline{AD}}}[/tex]
Which gives;
[tex]SF_{12} = \dfrac{3 \cdot \sqrt{13} }{\sqrt{13} } = 3[/tex]
The scale factor that takes Figure 1 to Figure 2, SF₁₂ = 3
(3 times the lengths of Figure 1 gives the lengths on Figure 2)
b. The scale factor that takes Figure 2 to Figure 1, SF₂₁, is given as follows;
[tex]SF_{21} = \mathbf{\dfrac{\overline{AD}}{\overline{PS}}}[/tex]
Which give;
[tex]SF_{21} = \dfrac{\sqrt{13} }{3 \cdot \sqrt{13} } = \mathbf{\dfrac{1}{3}}[/tex]
The scale factor that takes Figure 2 to Figure 1, SF₂₁ is [tex]\underline{\dfrac{1}{3}}[/tex]

Alex's expanded form for the number 165.038 is not correct. The correct expanded form for the number 165.038 is 100 + 60 + 5 + 0.03 + 0.008.
The number 165.038 can be broken down into its individual place values:
Hundreds: 100
Tens: 60 (6 tens)
Ones: 5
Tenths: 0.03 (3 hundredths)
Hundredths: 0.008 (8 thousandths)
So, the correct expanded form for the number 165.038 is:
100 + 60 + 5 + 0.03 + 0.008

can i get help for number 3???!?! please!!
Answers
Answer:
1.) 40 degrees
2.) 75 degrees
3.) 105 degrees
4.) 140 degrees
Step-by-step explanation:
Straight lines are = 180 degrees. Each of the angles you must solve have a given exterior angle. All you have to do is subtract the exterior angle from 180 to find the interior angle
1.) angle = 180-140
2.) angle = 180-105
3.) angle = 180-75
4.) angle = 180-40
Answer:
Measure of angle 1 is: 40 degrees
Measure of angle 2 is: 75 degrees
Measure of angle 3 is: 105 degrees
Measure of angle 4 is: 140 degrees
Step-by-step explanation:
Each of these angles is supplementary, meaning it adds up to 180 degrees,Thus, we can just subtract the measurement given from 180 to get our angle's measurement :)

Three consecutive integers add up to 51. The integers are *
16,17,18
15,16,17
17,18,19
18,19,20
Answers
Answer:
1st option
Step-by-step explanation:
let the three consecutive integers be n , n + 1 , n + 2 , then adding gives
n + n + 1 + n + 2 = 51, simplifying
3n + 3 = 51 ( subtract 3 from both sides )
3n = 48 ( divide both sides by 3 )
n = 16
n + 1 = 16 + 1 = 17
n + 2 = 16 + 2 = 18
The 3 consecutive integers are 16, 17, 18
[tex]\sqrt{x^{2}-16 }-3\sqrt{x-4}=0[/tex]
Answers
Answer:
[tex]\tt{} x_{1} = 4 \\ \tt{} x_{2} = 5 \\ [/tex]
Step-by-step explanation:
[tex]\tt{} \sqrt{ {x}^{2} - 16 } - 3 \sqrt{x - 4} = 0[/tex]
[tex]\tt{} \sqrt{ {x}^{2} - 16 } = 3 \sqrt{x - 4} [/tex]
[tex]\tt{}{x}^{2} - 16 = 9(x - 4)[/tex]
[tex]\tt{}(x - 4).(x + 4) = 9(x - 4)[/tex]
[tex]\tt{}(x - 4) \times (x + 4 - 9) = 0[/tex]
[tex]\tt{}( x - 4) \times (x - 5) = 0[/tex]
[tex]\tt{}x - 4 = 0 \\ \tt{}x - 5 = 0[/tex]
[tex]\tt{}x = 4 \\ \tt{}x = 5 \\ \\ [/tex]
[tex]\tt{} x_{1} = 4 \\ \tt{} x_{2} = 5 [/tex]
Answer:
x = 4, 5.
Step-by-step explanation:
√(x^2 - 16) - 3√(x - 4) = 0
√(x^2 - 16) = 3√(x - 4)
Square both sides of the equation:
x^2 - 16 = 9(x - 4)
x^2 - 9x - 16 + 36 = 0
x^2 - 9x + 20 = 0
(x - 4)(x - 5) = 0
x = 4, 5.
As the original equation contained square roots:
We test for extraneous solutions:
x = 4:
√(4^2 - 16) - 3√(4 - 4) = 0 - 3*0 = 0 so x = 4 is OK.
x = 5:
√(5^2 - 16) - 3√(5 - 4) = √9 - 3√1 = 0 so x = 5 is also OK.
