11x + 4 = 15x - 14

Subtract the like terms:

4 - -14 = -28

11x = 15x - 28

Then the other like terms:

-11x - 15x = -4x

-4x = -28

Divide -28 by -4 to get x:

-28/-4 = 7

x = 7

X=7
combine like terms 15x-11x is 4x. and 24+4 is 28. 28 divided by 4 equals 7

Is anyone able to solve this?

Olenka [21]

Explanation:

To find x we need to find the unknown side that connects the two triangles using the Pythagorean theorem:

a² + b² = c² (c is always hypotenuse)

So:

a² + 6² = 9²

a² = 9² - 6²

a² = 81 - 36

a² = 45

a = sqrt45

Now we do the same thing for the other triangle:

x² + 5² = sqrt45²

x² + 25 = 45

x² = 20

x = 2√5 or 4.5...

How do i factor x^4+6x^2-7 completly?

liq [111]

The factoring can be done similarly to a quadratic equation thanks to x^4 being the square value of x^2.

x^4 + 6x^2 - 7
x^4 - x^2 + 7x^2 - 7
(x^4 - x^2) + (7x^2 - 7)
x^2(x^2 - 1) + 7(x^2 - 1)
(x^2 + 7)(x^2 - 1)
(x^2 + 7)(x - 1)(x + 1)

Factored completely we get: (x^2 + 7)(x - 1)(x + 1)

The temperature went from -16°F to 7°F. What was the change in temperature?

Aleonysh [2.5K]

So you’re going from -16° to 7°. think of the equation as 16+7. you get 23. if the numbers go from a negative to a positive, the sun will be positive. so you’re answer is 23.
