Answer: 16

Step-by-step explanation: When you have a set of parentheses in an order of operations problem, you must simplify what's inside that set of parentheses first before you do anything else.

So our first step here is to subtract 6 - 8 which gives us -2.

So in our next step we have 3 (-2)² + 8 ÷ 2.

Now remember to do exponents before you multiply.

So (-2)² is just -2 × -2 or 4.

So in our next step we have 3 x 4 + 8 ÷ 2.

Now, we multiply so we have 3 x 4 which is 12.

So we have 12 + 8 ÷ 2.

Now we can divide.

8 ÷ 2 is 4 so we have 12 + 4 or 16.

So the answer to this problem is 16.

Answer: 16

Step-by-step explanation:

8 to the second power is 64 cause 8x8 equal 64 (/ is divided)

8x8= 64 - 6 = 58 + 4 = 62

8/ 2 = 4

The answer is 26 cause I did this before and it was a quiz for me and I got it right but I don’t remember how I solve it

In ΔWXY, w = 880 cm, ∠X=33° and ∠Y=38°. Find the length of y, to the nearest centimeter.
vladimir2022 [97]

Answer:

y\approx573cm

Step-by-step explanation:

First, take a look to the picture that I attached,  however please note the triangle is not drawn to scale, the figure is just to provide visual aid. As you can see the value of \angle W =109^{\circ} this is because of the sum of the interior angles in a triangle is always equal to 180°. So:

\angle W + \angle X + \angle Y =180\\\\\angle W = 180- \angle X -\angle Y\\\\\angle W =180-38-33\\\\\angle W=109

Now, we can use the law of sines, which states:

\frac{w}{sin(W)} =\frac{x}{sin(X)} =\frac{y}{sin(Y)}

Hence:

\frac{w}{sin(W)} =\frac{y}{sin(Y)}\\\\\frac{880}{sin(109)} =\frac{y}{sin(38)}\\\\Solving\hspace{3}for\hspace{3}y\\\\y=\frac{880*sin(38)}{sin(109)} \\\\y=572.9999518\approx 573 cm
