Answer:
9x, 4y, -2
Step-by-step explanation:
The terms are the constants or products that make up the sum that is the polynomial. They are ...
9x, 4y, -2
Okay. So, to find the percent change, we have to do change/original. In this case, it would be 12/15, because 15 and 27 are apart by 12. 12/15 is 0.8. Multiply that by 100 and you get 80. There was an 80% markup of the chair sold to the antique dealer.
Answer:

Answer:
AED and BEC, AEB and DEC i hope this helps! :)
Step-by-step explanation:
there are 2 sets of vertical angles shown in this picture
1st one is AED and im guessing its a C so...BEC
and the 2nd pair is AEB and DEC
they are both angles that are diagonal to each other.
AED is 62 degrees BEC is 62 degrees
AEB is 118 degrees DEC is 118 degrees
Answer:
A
Step-by-step explanation:
The sequence of positive odd numbers is
1, 3, 5, 7, ......
This is an arithmetic sequence with common difference d
d = 3 - 1 = 5 - 3 = 7 - 5 = 2
The sum to n terms of an arithmetic sequence is
=
[2a + (n - 1)d ]
where a is the first term
here a = 1, d = 2, n = 12, hence
=
[1 + (11 × 2) ]
= 6 [ 2 + (11 × 2) ]
= 6 × 24 = 144 → A
