I don't know how to do combing like terms someone help me!!!!

1 answer:

Just add them together. For example if you have 4x and 7x you would just do 4x+7x and get 11x. You can only add them because they are like terms, meaning that they share a variable.

I need help with this!

Answer:

Step-by-step explanation:

Let the width be w centimeters.

Then the length = w + 7.

The area A is found from the length multiplied by the width.

330 = w(w + 7) = w^2 + 7w.

Now we can rearrange this equation to form a quadratic, as follows:

The factorization of the quadratic is:

(w + 22)(w - 15) = 0

Therefore we find that:

width = 15 centimeters

length = 22 centimeters

Sin^22x - 2cos2x + 2=0

zhuklara [117]

Answer:

x=πn, n∈Z

Step-by-step explanation:

if sin²2x=1-cos²2x, then

1-cos²2x-2cos2x+2=0; ⇒ cos²2x+2cos2x-3=0; ⇔ (cos2x+3)(cos2x-1)=0;

$\left[\begin{array}{cc}cos2x+3=0\\cos2x-1=0\\\end{array} \ \ \left[\begin{array}{cc}x \ 'does-not-exist'\\cos2x=1\\\end{array} \ \ 2x=2\pi n, n=Z \ x=\pi n, n=Z$
