Answer: perfect square trinomials
Step-by-step explanation:
Although you don't provide the 4 multiple choice answers, here they are:
a) perfect square monomials
b) difference of terms
c) perfect square trinomials
d) difference of perfect squares
The answer is c) perfect square trinomials, for a perfect square trinomial is a trinomial that can be factored into a binomial multiplied to itself.
In the scenario of a perfect square trinomial, there will be 2 terms that'll be perfect squares. For example, in the trinomial x2 - 12x + 36, both x2 and 36 are perfect squares.
In this case, it is a special product formula because there's a specific formula for them — unlike the other answers.
I'm gonna go with triangle B. Triangles A,C,and E all look to be somewhat congruent in that they're all equilateral. Triangle D and F look similar but Triangle b looks like its isosceles and the others aren't like that.
Answer:
the percentage of profit is 45%
Given:
Each big square represents one whole.
To find:
The percent represented by the shaded area.
Solution:
One big square have 100 small square.
Shaded part of first big square = 100
Fraction of shaded part of first big square = ![\frac{100}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B100%7D%7B100%7D)
Shaded part of second big square = 19
Fraction of shaded part of second big square = ![\frac{19}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B19%7D%7B100%7D)
Fraction of total shaded area:
![$=\frac{100}{100}+\frac{19}{100}](https://tex.z-dn.net/?f=%24%3D%5Cfrac%7B100%7D%7B100%7D%2B%5Cfrac%7B19%7D%7B100%7D)
![$=\frac{100+19}{100}](https://tex.z-dn.net/?f=%24%3D%5Cfrac%7B100%2B19%7D%7B100%7D)
![$=\frac{119}{100}](https://tex.z-dn.net/?f=%24%3D%5Cfrac%7B119%7D%7B100%7D)
Percent of shaded area:
![$=\frac{119}{100}\times 100\%](https://tex.z-dn.net/?f=%24%3D%5Cfrac%7B119%7D%7B100%7D%5Ctimes%20100%5C%25)
= 119%
The shaded area is 119%.
Answer:
D. 96
Step-by-step explanation:
Using the Multiplication Principle, we multiply the number of choices for each item together:
![8 \cdot 4 \cdot 3 = 96](https://tex.z-dn.net/?f=8%20%5Ccdot%204%20%5Ccdot%203%20%3D%2096)
