please mark brainliest and have a nice day!
10+10=20 = length
20 + 18 = 38 width = 18 or 9 on each side
10 x 9 = 90
Answer 90
Not exactly sure which equation you meant:
3(100-b)=6b
300-3b=6b
300=9b
b= about 33
100-3b=6b
100=9b
b=about 11
Alexis needs to score at least 96 points on her next test in order to have an average of at least 90.
explanation:
85+89+92+96= 360
359/4=90
The sequence is
740, 707.60,675.20,642.80,...
Here first term is 740, and common difference, d is

Now we use the formula of nth term, which is

Substituting the values of a,n and d, we will get

Correct option is the second option .
