Simplify the expression: –9w+–6w+10w+8w

Y_Kistochka [10]

Final Answer: $3w$

Steps/Reasons/Explanation:

It is common addition and subtraction because they all have w after the number. This means they are the same variable. A plus minus (+-) would be a minus (-).

Question: Simplify the expression: $-9w +- 6w + 10w + 8w$ .

Step 1: Simplify.

$-9w - 6w + 10w + 8w$

Step 2: Simplify.

$3w$

Rini used a stick to draw a right triangle in the ground. The hypotenuse of her triangle is 24 inches and one of the legs is 12

Mademuasel [1]

Use the pythagorean theorem A² + B² = C²

A and B are legs and C is the hypotenuse

so- A² + 12² = 24² A² + 144 = 576
-144 -144

A² = 432 then you have to take the square root
of each side

so- A = √432 or aprox. 20.78

Greetings. As a beginner, I'm struggling a bit to learn calculus. May I know what is the derivative of x to the power 4 step by

If you're just starting calculus, perhaps you're asking about using the definition of the derivative to differentiate $x^4$ .

We have

$\dfrac{d}{dx} x^4 = \displaystyle \lim_{h\to0} \frac{(x+h)^4 - x^4}h$

Expand the numerator using the binomial theorem, then simplify and compute the limit.

$\dfrac{d}{dx} x^4 = \displaystyle \lim_{h\to0} \frac{(x^4+4hx^3 + 6h^2x^2 + 4h^3x + h^4) - x^4}h \\\\ ~~~~~~~~ = \lim_{h\to0} \frac{4hx^3 + 6h^2x^2 + 4h^3x + h^4}h \\\\ ~~~~~~~~ = \lim_{h\to0} (4x^3 + 6hx^2 + 4h^2x + h^3) = \boxed{4x^3}$

In general, the derivative of a power function $f(x) = x^n$ is $\frac{df}{dx} = nx^{n-1}$ . (This is the aptly-named "power rule" for differentiation.)
