Step-by-step explanation:
x-5=3(x+6)
x-3x=18+5
-2x=23
x=-23/2
Answer:
40
Step-by-step explanation:
2 • (3(5 + 2) - 1) =
Start with the innermost parentheses.
= 2 • (3(7) - 1)
Now do the multiplication inside the parentheses.
= 2 • (21 - 1)
Do the subtraction inside the parentheses.
= 2 • 20
= 40
Answer: 2 units.
Step-by-step explanation: When you graph the points given, it gives you this shape in the image below. The hypotenuse (longest side of triangle) is found by doing the following:
a^2 + b^2 = c^2, where a and b are the legs (the other sides of the triangle) and c is the hypotenuse.
5^2 + 2^2 = 29.
√ 29 ≈ 5.38, and that is the length of the hypotenuse.
The shortest side is the bottom side, which is 2 units. Therefore, that is your answer.
Let me know if this is right! :)
Answer:
Step-by-step explanation:
Positive integers are of the form 2n
The first term is 2 and the 130th term is 2(130)=260
The sum of this arithmetic sequence is the average of first and last terms times the number of terms
(2+260)(130/2)
