Scale Factor=4
I just counted how many units GF was and I came out with 5. Then I looked at the length of G’F’ and saw that it was at 20 units. 20/5=4
To find the common ratio, divide the 2nd term by the first term
-16 / 32 = -0.5....this means u multiply each number by -0.5 to find the next number
8 * -0.5 = -4 <==
-4 * - 0.5 = 2 <==
2 * -0.5 = -1 <==
answer D
Answer: 7
Step-by-step explanation: All you have to do is use absolute value when a number is closed in so you would say 63 divided by positive 9 = 7
Answer:
x-3
Step-by-step explanation:
(x
2
−9)=(x−3)(x+3)
(x
3
−27)=(x
3
−3
3
)=(x−3)(x
2
−3x+9)
(x
2
−8x+15)=(x−3)(x−5)
∴ H.C.F. of (x
2
−9),(x
3
−27) and (x
2
−8x+15) is x−3.
