Answer:
Multiplicación de polinomios cumple la propiedad distributiva.
Esta ley acostumbra a enunciarse diciendo que los factores se pueden agrupar de cualquier manera. Asimismo, el producto de polinomios también cumplía la propiedad conmutativa.
Step-by-step explanation:
Which information is not necessary to solve this problem? Five members of a club each brought 2 friends to their first meeting. There are 23 people in the club. How many member's friends came to the meeting? There are 23 people in the club. Five members brought friends. Some members brought 2 friends each.
Answer:
" There are 23 people in the club."
Step-by-step explanation:
We want to know how many member's friends came to the meeting.
We know that:
There are 23 people in the club
5 members of the club, invited 2 friends each.
So we have 5 times 2 friends invited:
Then there are 5*2 = 10 people invited to the first meeting.
Notice that the fact that there are 23 people in the club is never used, them the information that is not necessary to solve this problem is " There are 23 people in the club."

3(-1) + 6 < 14
3 + 6 < 14
9 < 14 ( true)
(3, 6)
3(3) + 6 < 14
9 + 6 < 14 ( not true)
(4, - 1)
3(4) - 1 < 14

State if the three numbers can be the measures of the sides of a triangle.
1) 10,8,6
2) 6, 18, 12
3) 8, 1,7
4) 7, 2,7
Answer:
Step-by-step explanation:
1) Makes a triangle. 6+8>10 In fact this one makes a right triangle. Try it using a = 6 b = 8 c = 10
2) 6 + 12 should exceed the third side. If these two just equal the third side (as these two do) then no triangle is formed.
3) Same with this one 7 + 1 = 8. No triangle is formed. Just a straight line
4) This one is fine. It makes an isosceles triangle with 2 sides = to 7. Any 2 are bigger than the third.
Bethany is making a rectangular fenced-in area for her rabbit in her yard. The area measures 4 3 4 feet wide by 2 yards long. What is the total length of fencing, in feet, that Bethany will need? A. 6 3 4 feet B. 10 3 4 feet C. 13 1 2 feet D. 21 1 2 feet
Answer:
D. 21 1/2 feet
Step-by-step explanation:
The total length of fencing, in feet, that Bethany will need is 13 1/2 feet.
What is the total length of fencing needed?The total length of fencing needed can be determined by calculating the perimeter of the area. Perimeter is the distance round the area.
Perimeter of the area = 2(length + width)
2 (4 3/4 + 2)
2 x 6 3/4
2 x 27/4 = 13 1/2 feet.

Answer:
h = 3
Step-by-step explanation:
Looking at the given image, the height(h) divides the side length of 8 into two equal parts as we see that the height is perpendicular to the side length of 8 m.
Thus, looking at the half triangle of the face where the h is indicated, we can use pythagoras theorem to find h where the hypotenuse is 5 as shown in the diagram since each vertical cross section is an Isosceles triangle. Thus,
h² + (8/2)² = 5²
h² + 4² = 25
h² + 16 = 25
h² = 25 - 16
h² = 9
h = √9
h = 3

Ms. Day gave a test to her four math classes. There are 25 students in each class. There were 8 A’s in her first class, 9 A’s in her second, 10 A’s in her third, and 7 A’s in her fourth class. If there are 150 students in the grade, which of the following is the BEST prediction of how many students will earn an A on this math test?
I think 34 students will get an A on their test.

Answer:
Y = 6 and X = 18
Step-by-step explanation:
The triangle on the far left in a triangle with all angles of the same value. This means that all angles are equal to 60 degrees, and we can use this information to find the angles for the far right triangle!
For the far right triangle, angle R is shown to be of an unknown value plus the value of 60 according to how a straight line always equals 180 degrees. This means that 180 = x + 60, or 120 equals x. x is the assigned variable for angle R on the far right triangle only. For this reason, as the two lines on that far right triangle show that angle T and angle S are congruent, we take 180, minus 120 from the previously found angle to equal 60. As angle T and angle S are congruent, we can divide 60 by 2 to equal 30. This means that the far right triangle has angle T as 30, and we divide 30 by 5 to equal 6. This means that y is equal to 6. Now let's find the value of x!
As the far left triangle has all congruent angle measurements, we can say that each side of that triangle has equal side lengths. This means that every side of the far left triangle has a side length of x - 7. As the far right triangle is an isosceles triangle, the sides on both sides of angle R are the same. This means that the value of 11 on side RS is also the value of 11 on side RT. As the far left triangle also shares this side with the value of x - 7, we can make the equation x - 7 = 11. This means that x is equal to 18!
Therefore, the value of y is 6 and the value of x is 18!

If sin A = 8/17 and tan B = 40/9 and angles A and B are in Quadrant I, find the value of * tan(A + B) .
Step-by-step explanation:
tanA=8/15 and tan B=40/9
tan(A+B)=(tanA+tanB)/1-tanAtanB
(8/15+40/9)/1-(8/15×40/9)
=-672/185
An athlete covers an elliptical race track of 400 m twice and halts at the starting point. What is the displacement and the distance covered by the athlete?
A.) 400 m and 800 m, respectively
B.) 0 and 800 m, respectively
C.) 1600 m and 800 m, respectively
D.) Both are zero.
Answer:
0and 800m respectively
b
Answer:
b. 0 and 800m respectively
Explanation:
the word "elliptical" means oval or egg-shaped. this means that the displacement of the athlete is 0 since they were running in a circle and stopped where they started, so their end position is not different from their original position.
the distance covered by them is 400m × 2 = 800m.

Which of these could be the graph of F(x)= 6 • (0.4)^x
Answer:
B
Step-by-step explanation:
to figure out which graph is the graph of the given function. we need to figure out the y-intercept:
to do so
recall exponential function
[tex] y = \displaystyle \: a {b}^{x} [/tex]
substitute 0 for x:
[tex] \displaystyle \: y=6 \cdot \: {0.4}^{0} [/tex]
recall law of exponent:
[tex] y = \displaystyle \: 6 \cdot \: 1[/tex]
simplify multiplication:
[tex] y = \displaystyle \:6[/tex]
now two graphs have (0,6) as y-intercept
but remember if b<0 then the function is decreasing
hence,
our answer is B
