12 + x to the power of 4 - 6 when x = 8

iren [92.7K]

value of $12+x^4-6$ at x=8 is $5002$ .

<u>Step-by-step explanation:</u>

here we need to evaluate 12 + x to the power of 4 - 6 when x = 8 or , $12+x^4-6$ where x=8 . Let's find out:

⇒ $12+x^4-6$

Putting x =8 :

⇒ $12+8^4-6$

Splitting 8 to power 4 into 8 to power 2 ( 2 times )

⇒ $12+8^2(8^2)-6$

⇒ $12+64(64)-6$

⇒ $12+4096-6$

⇒ $4096+6$

⇒ $5002$

Therefore , value of $12+x^4-6$ at x=8 is $5002$ .

Solve for x:<br> 4(1 – x) + 2 x = -3( x + 1)

valentinak56 [21]

Answer:

<u>4(1 – x) + 2 x = -3( x + 1)</u>

first do 4 time 1= 4

then do 4 times x =4x

now the equation should look like this

4-4x+2x=-3(x+1)

then do the other side of the equation

-3(x+1)

=-3x-3

Now collect the like terms:

-4x-2x

now the equation should look like this

4-2x=-3x-3

now add 3x add on both sides

4-2x+3x=-3

put the 4 on the other side

-2x+3x=-3-4

now again collect the like terms (-2x+3x=1 which is just x and -3-4 =-7)

x=-7

answer

x=-7

The perimeter of a playing card is 30 centimeters. The area is 50 square centimeters. What are the dimensions of the playing car

Arlecino [84]

Step-by-step explanation:

We get two equations here. One for the area and one for the perimeter. The area gives us x×y=50. The perimeter, if we have a rectangle, x+y+x+y=30=2x+2y. For this to work we need to make a simple expression for x or y. Let's go with x here. 2x+2y=30 so x=15-y. if we fill that in the other equation we get (15-y)×y=50 (see picture). y=5 or y=10. If we fill in x×5=50 we get x=10 and vice versa. So the dimensions are 5 centimeters by 10 centimeters

I need your help again guys!

solmaris [256]

ANSWER

$x = 13$

EXPLANATION

Use the Pythagoras Theorem to obtain,

${x}^{2} = {12}^{2} + {5}^{2}$

This implies that,

${x}^{2} = 144 + 25$

${x}^{2} = 169$

Take the positive square root of both sides to get,

$x = \sqrt{169}$

$x = 13$
