For wich values of x does 2x^2+10x

Answers

Answer 1

Answer: 2x^2 + 10x doesn't do anything, unless it's equal to something.

All you've got so far is a number. We can't even tell what it is
until we know what number 'x' is.

Is there another little part of the question that you didn't copy ?

Answer 2

Answer: Factor out at 2 so 2(x+5)(x+0)
Set them equal to 0 so
2=0 that's not a solution
X+5=0 so x=-5 that works
And the last one x=-0 well negative 0 doesn't exist so the only value that works is -5

What Is the next number? 12 21 23 32 34 43

Answers

12 21 23 32 34 43
so, we add 11 to 12 and get 23, then we add 11 to 23 and get 34, now we have to add 11 to 34 and get 45, that is the next number:
12 21 23 32 34 43 45 54

The next number of the number series 12 21 23 32 34 43 would be; 54

We are given the series as;

12 21 23 32 34 43

First, we have to add 11 to 12

11 + 12 = 23,

then we add 11 to 23

11 + 23 = 34,

Now we have to add 11 to 34

11 + 34 =45,

This is the next number:

12 21 23 32 34 43 45 54

A line segment is drawn from (+6, +4) to (+9, +4) on a coordinate grid.Which explains one way that the length of this line segment can be determined?

A.
Add 9 + 6.

B.
Add 6 + 6.

C.
Subtract 9 – 6.

D.
Subtract 6 – 6.

Answers

Letter c. add 9-6 explains one way that the length of this line segment can be determined. In order to verify this for yourself, you can plot these two point on a Cartesian coordinate plane and manually measure the length of the line. Mathematically, the length of a line may be calculated by the distance formula given as: sqrt[(x2-x1)^2+(y2-y1)^2]

In the __________ numbering system, all numeric values are written as sequences of 0s and 1s. a. hexadecimal b. binary c. octal d. decimal

Answers

Answer:

Therefore, the correct answer is b) binary.

Step-by-step explanation:

the binary numbering system, all numeric values are written as sequences of 0s and 1s. The binary system is a base-2 numbering system, which means it only uses two digits: 0 and 1. Each digit in a binary number represents a power of 2. For example, in the binary number 1010, the rightmost digit represents 2^0, the next digit represents 2^1, the next digit represents 2^2, and so on. Binary numbers are commonly used in computer systems to represent and manipulate data. Each binary digit, or bit, can represent two possible states: 0 or 1. By combining multiple bits, binary numbers can represent larger values.
