Answer:

a=9 , b=14

Step-by-step explanation:

Just do the operation (x+7)(x+2)

x(x)+x(2)+7(x)+7(2)

x^2+2x+7x+14

x^2+9x+14

So a=9 and b=14

Pythagorean triplets of 26​
Black_prince [1.1K]

Answer:

10,24,26

Answer step by step:

  • Phytagorean Theorem

The Pythagorean Theorem is a useful tool that shows how the sum of the areas of three intersecting squares can determine the side lengths of a right triangle.

  • Phytagorean Formula

\large{ \boxed{c =  \sqrt{ {a}^{2} +  {b}^{2}  }} }

With:

c = hypotenusa

a = upright side

b = pedestal side

Keep in mind that the Pythagorean formula only applies to right-angled triangles

  • Continue to discussion

26 =  \sqrt{ {10}^{2} +  {24}^{2}  }

26 =  \sqrt{(10 \times 10) + (24 \times 24)}

26 =  \sqrt{100 + 576}

26 =  \sqrt{676}

26 =  \sqrt{26 \times 26}

26 =  \sqrt{ {26}^{2} }

26 = 26

conclusion that prove that 10,24,26 is a Pythagorean triple.

Who knows the x and y values of<br> x+5y=-12<br> 5x+4y=24
musickatia [10]
Solve for one variable x or y first. So lets solve for x. If you take the first equation x= -12 -5y. You then plug that into the second equation
5(-12-5y) +4y = 24
now you solve for y
-60 - 25y + 4y =24
-21y=84
y=-4
Now you plug in y back into either equation and you get x=8
