Answer:
1/3
Step-by-step explanation:
A dilation is an enlargement or reduction of an image by a scale factor. The scale factor is the same ratio that cam be found from between the two figures.
The long leg of the original triangle has the length of 6. The small triangle has a long leg of length 2.
The ratio is 2/6 = 1/3.

Answer:
17
Step-by-step explanation:
_4 to +3 = 7
3 to 10 =7

the answer is 10+7=17
Answer:
see explanation
Step-by-step explanation:
note when x = - 3
(- 3)³ + 2(- 3)² + 4(- 3) + 21 = - 27 + 18 - 12 + 21 = 0
hence x = - 3 is a zero and (x + 3) is a factor and dividing gives
= (x + 3)(x² - x + 7)
For zeros equate to zero
(x + 3)(x² - x + 7) = 0
equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
x² - x + 7 = 0 ← solve using quadratic formula
x = (1 ±
) / 2 = (1 ± 3i
) / 2
x =
± 
zeros are x = - 3, x =
±
