Step 1. Check if both terms of your expression have a common factor.
Notice that both 28x and 4 are divisible by 4, so the common factor of your expression is 4.
Step 2. Take out the common factor by dividing each one of the terms by the common factor and grouping the results inside a parenthesis:
and
We can conclude that the factored form of
is
.
To obtain an overall average of 86%, a score of 96 is required on her 4th test.
Let the required score on her fourth test = t
The required average = 86%
Initial scores : 80% + 83.5% + 84.5%
Average = ΣX/ (fx)
fx = total score obtainable = 4 × 100 = 400
ΣX = sum of scores
Average = 86%
0.86 = ((80 + 83.5 + 84.5 + t) / 400)
86 = (248 + t) / 400
400 × 0.86 = 248 + t
344 = 248 + t
344 - 248 = t
96 = t
In other to obtain an overall average of 86%, she has to score 96 in her 4th test.

Wheres the rest of the question, or is that it?
Step-by-step explanation:
f(1)= 64+6(1)
=64+6
=70.
thus, f(1) = 70
f(n)=f(n-1)+?
1=(1-1)+70
1=0+70
=70-1
=69
Answer:
3/26
Step-by-step explanation:
The face cards are: Jack, Queen, and King. There are only three face cards for each of the 4 suits.
Among the 4 suits, two of them are red: diamonds and hearts. And, each of these two has 3 faces. That means that in a deck of 52 cards, there are 2 * 3 = 6 cards that are both red cards and face cards.
Probability is (# times specific event can occur) / (# times any general event will occur).
Here, the specific event is drawing a card that is both red and a face card (of which there are 6 ways), and the general event is drawing a card (of which there are 52 ways):
P(draw a card that is both red and a face card) = 6/52 = 3/26
