À because a consumer is the customer so your answer would be A
I think this place value drawing isn't taught to everyone, could you provide a picture of one?
Answer:
(x - 7y)/(x + 3y)
Step-by-step explanation:
x² - 5xy - 14y²
x² - 7xy + 2xy - 14y²
x(x - 7y) + 2y(x - 7y)
(x - 7y)(x + 2y)
x² + 5x + 6y²
x² + 3xy + 2xy + 6y²
x(x + 3y) + 2y(x + 3y)
(x + 3y)(x + 2y)
[(x - 7y)(x + 2y)] ÷ [(x + 3y)(x + 2y)]
(x - 7y)/(x + 3y)
First one is arithmetic sequence in disguise
an=a1+d(n-1)
a1=first term
d=common differce
n=which term
so
first erm is 4
common difference is 9-4=5
an=4+5(n-1)
when n=10
4+5(10-1)
4+5(9)
4+45
49
B
3.5, to 6.5, 9.5
aritmetic, increase by 3, first term is 3.5
an=3.5+3(n-1)
10th term
3.5+3(10-1)
3.5+3(9)
3.5+27
30.5
A is49
B is 30.5
A is answer
an=a1+d(n-1)
115+(-8)(14-1)
115-8(13)
115-104
11
answer is B
an=a1+d(n-1)
45+(-3)(10-1)
45-3(9)
45-27

C
<em>x = 1</em>
<em><u>Here is why:</u></em>
Add x to both sides.
Add 5 to both sides.
Divide.
x = 1
