Answer:
(x - 3) • (x^2 - 4x - 7)
Step-by-step explanation:
Step 1 :
Trying to factor by splitting the middle term
1.1 Factoring x2-4x-7
The first term is, x2 its coefficient is 1 .
The middle term is, -4x its coefficient is -4 .
The last term, "the constant", is -7
Step-1 : Multiply the coefficient of the first term by the constant 1 • -7 = -7
Step-2 : Find two factors of -7 whose sum equals the coefficient of the middle term, which is -4 .
-7 + 1 = -6
-1 + 7 = 6
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Final result :
(x - 3) • (x2 - 4x - 7)

Here is what another branily user said:
If you are travelling at 65 mph, you have to think of it as if you are moving at a constant speed. By dividing 65 by 60, you are calculating how many miles you are moving each minute. In doing so, you can calculate that you are moving at 1.083333 miles each minute. That's approximately 5720 feet per minute. (This is calculated by multiplying 1.083333 by 5280 (the number of feet in a mile)). 5720 x 22 minutes, you will have traveled 125,840 feet.
Answer:
3
Step-by-step explanation:
The scale factor of ABC to DEF is the number you need to multiply a corresponding side of ABC to get one of DBC. We are given the two triangles are similar, so we can say that sides AB and DE are proportional. We are looking for the number we need to multiply AB by to get DE. From this relation, we can get the equation:
AB * x = DE
where x is our scale factor. We can substitute in the values of AB and DE, and solve for x:
5x = 15
x = 3
Therefore, the scale factor is three. This means that you can multiply any side of ABC by 3 to get a side of DEF.
Answer:
7.8 × 10-5 meters
Step-by-step explanation:
the length of the a human hair= 8.4 x 10^-5
length of the vicuna hair:0.000006 = 0.6 x 10^-5
===========================================
difference between human hair and vicuna hair:
8.4 x 10^-5 - 0.6 x 10^-5 = 10^-5 ( 8.4 - 0.6)
= 10^-5 (7.8)
= 7.8 x 10 ^-5 meters
She should check her actual quotient again, carefully. Something is
definitely wrong. The spread between her estimate and the actual
quotient is too much. She probably made a mistake with (at least)
one of them.
Since the estimate was just for her own convenience and the actual
quotient was the one that really counts, she should go straight to the
actual quotient and look there for a mistake first.
