Answer:
Enlargement.
Scale Factor: 3
Step-by-step explanation:
Use points to find the enlargement. Typically, you will use all the points.
A(1 , 1) ⇒ A'(3 , 3)
B(2 , 1) ⇒ B'(6 , 3)
C(1 , 2) ⇒ C'(3 , 6)
D(2 , 2) ⇒ D'(6 , 6)
To find the scale factor, simply divide the Point' with the original Point. Use any number.
A'(3 , 3)/(A(1 , 1)) = 3
B'(6 , 3)/(B(2 , 1)) = 3
C'(3 , 6)/(C(1 , 2)) = 3
D'(6 , 6)/(D(2 , 2)) = 3
Your scale factor is 3.

Answer:
76
Step-by-step explanation:
38 multiplied by 2 = 76
Answer:
Step-by-step explanation:
<h3>Given AP </h3>
<h3>To find</h3>
<h3>Solution</h3>
- a₁₂ = a + 11d = 62
- a₂₀ = a + 19d = 102
<u>Subtract the first equation from the second one:</u>
<u>Find a:</u>
- a + 11*5 = 62
- a = 62 - 55
- a = 7
<u>Find the sum of the first 20 terms:</u>
- S₂₀ = 1/2*20(a + a₂₀) = 10(7 + 102) = 10(109)= 1090
