Answer:

The Pythagorean theorem states that: In any right triangle, the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares whose sides are the two legs (the two sides that meet at a right angle).

Step-by-step explanation:

The Pythagorean Theorem, a2+b2=c2,a2+b2=c2, is used to find the length of any side of a right triangle

• In a right triangle, one of the angles has a value of 90 degrees

• The longest side of a right triangle is called the hypotenuse, and it is the side that is opposite the 90 degree angle

• If the length of the hypotenuse is labeled cc, and the lengths of the other sides are labeled aa and bb, the Pythagorean Theorem states

that a2+b2=c2a2+b2=c2 that a2+b2=c2a2+b2=c2

Answer:

$\frac{5}{4}+or-\frac{3i\sqrt{7} }{4}$

Step-by-step explanation:

You can solve this equation with the quadratic formula which is:

$m_{1,2}=\frac{-b+or-\sqrt{b^{2}-4ac } }{2a}$

All you need to do is rearrange the equation (add $-\frac{11}{2}$ to both sides and then multiply both sides by 2) to get:

$2m^2-5m+11=0$

From this new equation, we can easily see that a = 2, b = -5, and c = 11 AND you don't have to work with as many fractions. Substitute the values for a, b, and c into the quadratic formula to get:

$m_{1,2}=\frac{5+or-\sqrt{(-5)^{2}-4(2)(11) } }{2(2)}$

That simplifies to:

$\frac{5}{4}+or-\frac{\sqrt{25-88} }{4}$

Which simplifies even further to:

$\frac{5}{4}+or-\frac{\sqrt{-63} }{4}$

Which gets you:

$\frac{5}{4}+or-\frac{3i\sqrt{7} }{4}$

P.S. The plus-minus sign wasn't working for me, so I had to just write, "+or-". I hope that didn't make it too confusing for you.

P.P.S. Hope this helps :) Don't forget to mark Brainliest if it did.

Is p=7 a solution of the equation 4p - 5 =16

Ann [662]

No.

4p - 5 = 16

Isolate the variable and the constant.

4p = 21

p = 21/4

What is the answer to X+4x=-2 and show your work

Setler79 [48]

I think you meant 'x + 4x = -2'

Combine like terms:

5x = -2

Divide 5 to both sides:

x = -2/5 or -0.4

Is algebra.

Answer:

$6(x-10)(x+9)$

Step-by-step explanation:

First, make A equal one by factoring out the greatest common factor, 6. This makes the new expression $6(x^{2} +x-90)$ . Then, factor the remaining polynomial by finding two numbers that multiply to -90 and add to 1. These two numbers are -10 and 9. So, add each term to x and then multiply to get the final answer, $6(x-10)(x+9)$ .

Answer:

Step-by-step explanation:

First divide 2/5 to get 0.4. Then divide 30 by 0.4 to get the answer. A simple way to think about it is how many 0.4 grams are in 30 gram tube.
