Mathematics

Answer:

No, is not a Pythagorean triple

Step-by-step explanation:

To know if you can build a right triangle with those sides we have to make the following equality

h² = l1² + l2²

The hypotenuse is always the longest side so it should be 30

we check the equality of the equation

30² = 14² + 22²

900 = 196 + 484

900 = 680

Equality was not fulfilled so it is a right triangle

Write your answer in standard form. (6x+7) (x-8)
WITCHER [35]

Answer:

First one is d and second one is c

Step-by-step explanation:

(6x+7)(x-8)

(6x)(x) = 6x^2

(6x)(-8) = -48

(7)(x) = 7x

(7)(-8) = -56

Add all like terms together and you get choice d.

(w+3)(w-3)

(w)(w) = w^2

(w)(-3) = -3w

(3)(w) = 3w

(3)(-3) = -9

Add all like terms together and you get choice c

What is the value of x, when 10(x + 2) = 5(x + 8)?
tatuchka [14]
The value of x is 4. The steps to solving the equation are to use distributive property first so that the equation then looks like this: 10x+20=5x+40
Next you would combine like terms and then the equation would look like this: 5x+20=40
Then you would use the subtraction property of equality to subtract 20 from 40 so your equation will now look like this: 5x=20
Then you use the division property of equality to divide 20 by 5 to get x=4

Ron works 5 hours for a total of $300. He deposits all of his money in his account. He is trying to save $500 for a new LED TV.
hoa [83]
He must work about 4-5 more hours, and if he works 4 hours, he would earn $240, and $300 + $240 = $540. Or, if he works for 5 hours, it would equal $300. $300 + $300 IS $600, and his savings may be $60 or $100. Your Choice.
