Answer:

hypotenuse = aprox 18.6

Step-by-step explanation:

a^2 + b^2 = c^2

11^2 + 15^2 = c^2

346 = c^2

square root both sides

c = aprox 18.6

hope that helped!

3(7x+4)-x as an infinite equation
Sidana [21]

Answer: 20x+12

Step-by-step explanation:

Distribute the three: 3(7x+4) will be changed to 21x+12-x

Next group like terms, -x+21x=20x

The new equation will be 20x+12

Nutka1998 [239]

let's plug the value of x and y as 5 and 4 respectively to find the value of given expression :

  • 7 {y}^{2}  + 15x - 22

  • 7(4) {}^{2}  + (15 \times 5) - 22

  • (7 \times 16) + 75 - 22

  • 112 + 53

Could 10.3cm 4.4cm and 8.3 cm be the side lengths of a triangle yes or no
evablogger [386]

Answer:

No

Step-by-step explanation:

As you probably know, triangles have 3 sides. The longest side is called the hypotenuse. In this case, the hypotenuse is 10.3. Now, you might or might not know the pythagorean theorem, which states that the <em>a² + b² =c ². </em>

In this case, we can say that 4.4 is <em>a </em>and 8.3 is <em>b. </em>Now if we square 4.4 and add it to 8.3 squared, we get 88.25. However, if you square 10.3, you get 106.09. Thus, the values cannot be this way. So, your answer is no.

Please solve the math question: |4x−4(x+1)|=4
alexgriva [62]

Answer:

x has infinite solutions

Step-by-step explanation:

|4x−4(x+1)|=4

Simplify inside the absolute value by distributing the 4

|4x−4x+4|=4

Combine like terms

|4|=4

The absolute value of 4 is 4

4=4

This is always true, so x is all real values

x has infinite solutions
