Answer:
2, 6, 12, 20, 30
Step-by-step explanation:
To find the first 5 terms substitute n = 1, 2, 3, 4, 5 into the expression
n = 1 → 1² + 1 = 1 + 1 = 2
n = 2 → 2² + 2 = 4 + 2 = 6
n = 3 → 3² + 3 = 9 + 3 = 12
n = 4 → 4² + 4 = 16 + 4 = 20
n = 5 → 5² + 5 = 25 + 5 = 30
Answer:
<u>x=-1.5</u>
Step-by-step explanation:
To solve for x, you need to rearrange so the x is on one side of the "=" by itself.
So To do that, first you need to subtract 1/4 on both sides of the "=". This leaves you with 1/2+x=-3/4-1/4. You can simplify the -3/4-1/4 to -1 (-4/4). So, you now have 1/2+x=-1.
The next step is to subtract 1/2 on both sides of the "=". This leaves you with x=-1-1/2. Again, you can simplify the -1-1/2 to -3/2 which can be written as -1.5. So, you now have x=-1.5, which is the final answer.
The question may ask you to write your answer in the form of a fraction, in which case your answer x=-3/2. If the questions wants it written as a mixed number, your answer would be -1 1/2.

50/X = 40/100
50 × 100 = 40 × X
5000 = 40X
5000/40 = 40X/40
125 = X
Answer:
Area=2232 square ft
Perimeter=206 ft
Step-by-step explanation:
given
the diagram is a rectangle
length=72 ft
width=31 ft
we know that
formula of the area of rectangle= length × width
Area=72×31 square ft
Area=2232 square ft
Now calculate the perimeter
perimeter of rectangle=2(length+width)
perimeter=2(72+31)
perimeter=2(103)
perimeter=206 ft
