Answer:
2.25
Step-by-step explanation:
The question gives us one hint. That side of the square is 1.5"
Because it gives us that, we can use that to find the area. Because it is a square, all of the sides are the same length.
To find the area it is basexheight
So that is why the answer is 2.25 because 1.5x1.5=the area of the square
Answer:
17
Step-by-step explanation:
because there are numbers involved
5x⁴ - 3x³ + 6x) - (3x³ + 11x² - 8x)<span>
</span>Expand the second bracket by multiplying throughout by -1
5x⁴ - 3x³ + 6x - <span>3x³ - 11x² + 8x
</span>
Group like terms and simplify
5x⁴ - 3x³ - 3x³ - 11x² + 6x <span>+ 8x
</span>5x⁴ - 6x³ - <span>11x² + 14x</span>
Answer:
.
Step-by-step explanation:
Start by separating this decimal number into its integer part and its fraction part:
![4.151515\cdots = 4 + 0.151515\cdots](https://tex.z-dn.net/?f=4.151515%5Ccdots%20%3D%204%20%2B%200.151515%5Ccdots)
The most challenging task here is to express
as a proper fraction. Once that fraction is found, expressing the original number
will be as simple as rewriting a mixed number as an improper fraction.
Let
.
would then represent the original number.
Note that the repeating digits appear in groups of two. Therefore, if the digits in
are shifted to the left by two places, the repeating part will continue to match:
.
Note, that this "shifting" is as simple as multiplying the initial number by
(same as
raised to the power of the number of digits that needs to be shifted.)
Subtract the original number from the shifted number to eliminate the fraction part completely:
.
In other words:
.
.
Therefore, the original number would be:
.
Responder:
A - B = {1, 4, 5}
Explicação passo a passo:
Conjunto A - Conjunto B; Isso significa que queremos um conjunto que contém apenas elementos que estão no conjunto A, portanto, os elementos do conjunto A que também estão presentes no conjunto B estão isentos.
A = {1, 2, 3, 4, 5}
B = {2, 3, 7}
A - B = {1, 4, 5}
Portanto, apenas] 1, 4, 5} são elementos do conjunto A e não do conjunto B
