I CAN HELP YOUUUUUUUUUUUUUUUUUU!!!!!!!!!!!!!!!!!!1
lets distribute 7(x+3)
so 7(x)+7(3)
7x+21 or b
yay :)
Answer:r = -1
Step-by-step explanation:
8+8r-(3+3r)=0
We add all the numbers together, and all the variables
8r-(3r+3)+8=0
We get rid of parentheses
8r-3r-3+8=0
We add all the numbers together, and all the variables
5r+5=0
We move all terms containing r to the left, all other terms to the right
5r=-5
r=-5/5
r=-1
Hope this helps
The length of the rectangle is 16.
Answer:the 57th term is 78
Step-by-step explanation:
The sequence is an arithmetic sequence. The formula for determining the nth term of an arithmetic sequence is expressed as
Tn = a + (n - 1)d
Where
a represents the first term of the sequence.
d represents the common difference.
n represents the number of terms in the sequence.
From the information given,
a = - 6
d =3/2
n = 57
We want to determine the value if the 57th term, T57. Therefore,
T57 = - 6 + (57 - 1) ×3/2
T57 = - 6 + 56 × 3/2 = - 6 + 84
T57 = 78
