or if you want fraction
22/486 can be simplified to 11/243 by dividing both the numerator and denominator by 2
Answer:
A
Step-by-step explanation:
For b, the constant term is 3, not -3. B is incorrect.
For c, when the brackets are removed using foil, -3 * - 3 = 9. C is incorrect.
For d, There is no reduction, alteration or math procedure that you can use that will make the constant term anything but 9. The answer is not D.
======================
That means you are left with A which must be right or the question isn't. Turns our that A is the answer -3 * 1 = - 3
Answer: 28 and 30
Step-by-step explanation:
Let the house numbers on the street be represented by n and n+2 sine they are consecutive even integers. Therefore,
n + (n + 2) = 58
2n + 2 = 58
2n = 58 - 2
2n = 56
n = 56/2
n = 28
Therefore the second number will be:
= n + 2
= 28 + 2
= 30
The numbers are 28 and 30
Answer:
Side 1=21 ft, Side 2=7, Side 3=24
Step-by-step explanation:
52 = (3x) + (x) + (x+17) -> 52 = 5x + 17 -> 5x = 35 -> x = 7
Plus 7 into the equation whenever you see an x.
Answer:
9.8
Step-by-step explanation:
a geometric sequence means we multiply the previous element by a certain factor to get the next element.
so, all we need to do is determine the factor used to go from one element in the list to the next.
a1 = 9
a2 = 88.2
a3 = 864.36
a4 = 8470.728
the simplest case is usually the case from a1 to a2.
a2 = a1×f
88.2 = 9×f
f = 88.2/9 = 9.8
we are finished here.
but we can control our result and verify with the other given elements.
88.2 × 9.8 = 864.36
and that is a3. fits.
864.36 × 9.8 = 8470.728
and that is a4.
so, all fits, we are correct.
