Need help with my algebra 1 assignment. Help would be apprecitated. thanks so much!

Answer:

See the answer below.

Step-by-step explanation:

The Pythagoras theorem for a right triangle is

c^2 = a^2 + b^2     where c = hypotenuse and a, b are the legs of the triangle.

3  positive integers which fit this formula  are called Pythagorean Triples.

3,4 5 are a triple because 5^2 = 3^2 + 4^2 ( 25 = 9 + 16).

and also  17^2 = 15^2 + 8^2  ( 289 = 225 + 64).

Step-by-step explanation:

Pythagorean theorem is [tex]a^{2} + b^{2} =c^{2}[/tex] (c being the largest number)

Pythagorean triples are 3 positive numbers that make this equation true.

let's start with 3,4,5

3²+4²=5²

9+16=25

25=25

Since it's true, it's a triple.

Now 8,15,17

8²+15²=17²

64+225=289

289=289

This is also true, so it's also a triple

Hope this helps!

Step-by-step explanation:

If you know the radius of the circle, double it to get the diameter. The radius is the distance from the center of the circle to its edge. If the radius of the circle is 4 cm, then the diameter of the circle is 4 cm x 2, or 8 cm. If you know the circumference of the circle, divide it by π to get the diameter

there’s 2 basic cases you’ll see to find the diameter (a line that basically cuts the circle in half)

you’ll either be given the radius (the distance between the center of the circle to any point on the circle) or the circumference (the perimeter of the circle)

so you have two equations:

diameter= 2*radius

circumference= diameter * pi

if they gave you the radius, simply multiply by 2 as the first equation states. if they give you the circumference, divide the circumference by pi (which is approx. 3.14)

Answer:

the numbers are -20 and 5

Step-by-step explanation:

The value of a = -20 and b = 5.

Let the numbers be a and b

a + b = -15 ...... i

a × b = -100 ....... ii

From equation i,

a = -15 - b ..... iii

Put equation iii into ii

a × b = -100

(-15 - b) × b = -100

-15b - b² = -100

-15b - b² + 100 = 0

b² + 15b - 100 = 0

b² + 20b - 5b - 100 = 0

b(b + 20) - 5(b + 20) = 0

b - 5 = 0

b = 0 + 5 = 5

a + b = -15

a + 5 = -15

a = -15 - 5

a = -20

Therefore, the value of a = -20 and b = 5.

Step-by-step explanation:

Answer:

A. x=5

Step-by-step explanation:

8x+3(3-x)=34

We move all terms to the left:

8x+3(3-x)-(34)=0

We add all the numbers together, and all the variables

8x+3(-1x+3)-34=0

We multiply parentheses

8x-3x+9-34=0

We add all the numbers together, and all the variables

5x-25=0

We move all terms containing x to the left, all other terms to the right

5x=25

x=25/5

x=5

I think this is correct.

Answer: its A; x=5

Step-by-step explanation:

8x+3(3-x)=34

distribute the 3 through the parentheses

8x+9-3x=34

then add the like terms

5x+9=34

subtract the 9 to the 34

you shoud get

5x=25

then divide the 5 on both sides and you get your answer of x=5
