400x6=2400 This is how a find a product
Answer:
Step-by-step explanation:
TO find the value for the terms, substitute n for the number in the sequence. so
for 1st term n = 1
for 2nd term n =2 etc.
1st Term = 1^2-3 = 1-3 = -2
2nd term = 2^2 - 3 = 4-3 = 1
3rd Term = 3^2 - 3 = 6
10th Term = 10^2 - 3 = 100 - 3 = 97
Hope this helps
the answer would bex squared + 3x - 28
Total=255*5=1275
fifth week earning=1275-(246+288+234+276)
=231
Solve for n.
0.2(n - 6) = 2.8
Distribute
0.2*n - 0.2*6 = 2.8
0.2n - 1.2 = 2.8
Now inverse operation should be applied
0.2n - 1.2 = 2.8
+ 1.2 +1.2
2.8 + 1.2 = 4
0.2n = 4
0.2n/0.2 = 4/0.2
n = 20
Answer: 20
