(13x+14)(6x-5)=0
78x²-65x+84x-70=0
78x²+19x-70=0
It was equation.
______________
Factoring⇒ a×c=78×(-70)=-5460
84×(-65)=-5460
84+(-65)=19 which is b

(13x+14)(6x-5)=0
13x+14=0 6x-5=0
13x=-14 6x=5
x=-14/13 x=5/6
Two solution X=-14/13;5/6
If you simplify the expression, you will get A, E and D
The next step Nolan should take is to find the average of the distances from the mean.
<h3>What is meant by mean absolute deviation?</h3>
A measure of variance in a data set is the mean absolute deviation. We may determine how "spread out" the values in a data collection are by looking at the mean absolute deviation.
The steps to find mean absolute deviation are:
- Calculate the mean of the data set
- Calculate the value of distance between the mean and each point in the data set.
- Find the average of the distances from the mean.
Hence, The next step Nolan should take is to find the average of the distances from the mean.

Answer:
15-6x= -12-4x
15-2x= -12
-2x= -27
x= -13.5
Step-by-step explanation:
Answer: (2p + 1.5d) + (5*(2)) = T
Step-by-step explanation: (2p + 1.5d) + (5*(2)) = T
Since there are no costs, i'll make up my own uwu;
Matinee = $5
Popcorn = $2
Drink = $1.5
T = total
(2p + 1.5d) + (5*(2)) = T
2p ($2 for each bag of popcorn - p represents popcorn)
1.5d ($1.5 for each drink, - d represents drinks)
5*2 ( 5 * 2 because we are already given the amount of matinee tickets they buy.
