PLEASE HELP ASAP FOR 10 POINTS

Mathematics
1 answer:
RUDIKE [14]3 years ago
5 0
The easiest way to do this is to distribute one term to the second set of parentheses and add eveything. Start with x2 and distribute to get x^4 + x^3 + 2x^2. Then the 3x distributed gets you 3x^3 + 3x^2 +6x. Finally the 1 distributed gets you x^2 + x + 2. You add all three answers together to get x^4 + 4x^3 + 6x^2 + 7x + 2

Finding theoretical probability throwing a dart in a 3x3 yellow square that is centered inside a 6x6 blue square
nydimaria [60]
The probability of hitting the yellow square is 1/4.

The area of the yellow square is given by 3*3 = 9.
The area of the blue square is given by 6*6 = 36.

You have a 9/36 chance of hitting the yellow square; 9/36=1/4.

Katherine is younger than Alexandra. Their ages are consecutive integers.
Serjik [45]

Using equations to solve the word problem, Katherine's age is 8 years

<h3>Word Problem</h3>

Word problem are often mathematical problem that are represented in words and sometimes can be solved using an equation.

To solve this problem, we have to represent the problem using mathematical equations;

Let;

Katherine's age = x²

Alexandra = 5(x + 1)

Sum of their age = 109

5(x + 1) + x² = 109

5x + 5 + x² = 109

x² + 5x - 104 = 0

Solving for the equation; x = 8

Katherine's age is 8

I need to know the points of T and how to get it
german

Answer: (-2, -2)

Step-by-step explanation:

When you approach these types of questions, first look for a pattern. Both the x and y value are divided by 2.5 in the image, so do the same with point t. The image would be -5/2.5, -5,2.5 or -2, -2

What is the solution of the system of equations?
umka21 [38]

No solution of the system of equations y = -2x + 5 and -5y = 10x + 20 ⇒ 2nd answer

Step-by-step explanation:

Let us revise the types of solutions of a system of linear equations

  • One solution
  • No solution when the coefficients of x and y in the two equations are equal and the numerical terms are different
  • Infinitely many solutions when the coefficients of x , y and the numerical terms are equal in the two equations

∵ y = -2x + 5

- Add 2x to both sides

∴ 2x + y = 5 ⇒ (1)

∵ -5y = 10x + 20

- Subtract 10x from both sides

∴ -10x - 5y = 20

- Divide both sides by -5

∴ 2x + y = -4 ⇒ (2)

∵ The coefficient of x in equation (1) is 2

∵ The coefficient of x in equation (2) is 2

∴ The coefficients of x in the two equations are equal

∵ The coefficient of y in equation (1) is 1

∵ The coefficient of y in equation (2) is 1

∴ The coefficients of y in the two equations are equal

∵ The numerical term in equation (1) is 5

∵ The numerical term in equation (2) is -4

∴ The numerical terms are different

From the 2nd rule above

∴ No solution of the system of equations

No solution of the system of equations y = -2x + 5 and -5y = 10x + 20
