Hey there!
a.) 1 inch
beginning = 2; end = 3; difference of 1
b.) December, because the length was, let's say, 2, then it went down 1 (so we're at 1), then went up 3 (4), then went down
c.) in December
Hope it helps, have a great day!
Answer:
f(x) = x² + 2x + 1
Step-by-step explanation:
you know how to multiply 2 expressions ?
let's say in general we have
(a + b)(c + d)
you take one part of one expression and multiply it with all parts of the other expression, then you take the second part of the first expression and multiply it with all parts of the other expression, then a potential third part, then a fourth part and so on, and you add all these things together (well, depending on the actual signs, of course).
so, we get for this simple generic example
a×c + b×c + a×d + b×d
now we use that understanding for our question here.
(x+1)(x+1) = x×x + 1×x + x×1 + 1×1 = x² + x + x + 1 = x² + 2x + 1
Well the square root of 72 is 8.485 and the square root of 45 is 6.708. hope this helps :)
To find perimeter you multiply.
164.042*82.021=13454.888888882 (8 repeating)
Let S represent the cost of use of Silver Gym for a month.
Let F represent the cost of use of Fit Factor for a month.
Let T represent the number of training sessions used in the month.
S = 45 +25T
F = 75 +15T
We want to find T so the costs are equal.
.. S = F
.. 45 +25T = 75 +15T
.. 10T = 30 . . . . . . . . . subtract 45+15T
.. T = 3 . . . . . . . . . . . . divide by 10
Sarah would have to buy 3 training sessions to make the cost at the two gyms equal.
