Answer:
d.
Step-by-step explanation:
Since it's an isosceles triangle, WX=WZ= 2n-5
Perimeter = n + (2n-5) + (2n-5)
= 5n - 10
The Perimeter is given to be 20
5n - 10 = 20
5n = 30
n = 6
Answer:
the last bullet point I guess is the answer
The scneario here expressed is an aritmetic sequence because it can be explained like this:
<span><span><span>a1</span>=35
</span><span><span>an</span>=<span>a<span>n−1</span></span>+<span>17
So all the variables can fit in and will be better explained than a geometric sequence in which you need a common ratio and that is not needed in this case</span></span></span>
Answer:
-23
Step-by-step explanation:
calculate,
3^2 x (-2) -5
multiply, evaluate the power,
-9 x 2-5
multiply the numbers,
-18 -5
calculate,
-23
So your answer is -23
20000 divided by 75 is 266.6666666667
