1 answer:

Answer:

15.6 inches

Step-by-step explanation:

Here we want to find the length of the missing side

Mathematically, we can use Pythagoras’ theorem

The theorem states that the square of the hypotenuse equals the sum of the squares of the two other sides

Let the missing side be x

18 is the side that faces right angle and this is the hypotenuse

Thus, we have ;

x^2 + 9^2 = 18^2

x^2 = 324 - 81

x^2 = 243

x = √(243)

x = 15.6 in

Is -2 considered a real number
lyudmila [28]

Yes. If we wanted to get even more specific, -2 is an integer, which falls under the label of the real numbers. √-2, on the other hand, is an imaginary number. The square root of -1 doesn't exist in the real numbers, so we invent a new number i with the property that i² = -1. Blending real and imaginary numbers together creates <em>complex numbers, </em>numbers with a real and imaginary part. This extension of the number system is tremendously useful because it essentially makes numbers two-dimensional, allowing us to manipulate and study them through a geometric lens.

Solve this problem: 3(6 - 8)² + 8÷2<br> A-8<br> B-16<br> C-28<br> Will mark Brainliest!!
marishachu [46]

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.
