Write answer in scientific notation

Answer:

a. (x+5)^2 = 49

b. (x+7)^2 = (x+1)^2

Step-by-step explanation:

So the term "a number" is always going to be x. input x into the sentences. "X plus five, then squared, is forty-nine". when they do "is __", that means equal to. In the second question, seven more than x is x + 7 (the two numbers are interchangeable here). Equivalent also means equal. hope this helped :)

Answer:

a: x + 5^2 = 49

b: 7>x^2=(put three lines not two) (1>x)^2

Answer:

57

Step-by-step explanation:

Answer: 57

Step-by-step explanation:

1. Calculate what's in the parentheses first

(4 * 15) = 60

(60) - 3 = ?

2. Exponents (Powers, Roots) before you Multiply, Divide, Add or Subtract

Not applicable for this problem.

3. Multiply or Divide before you Add or Subtract

Not applicable for this problem.

4. For anything else left, just go from left to right

60 - 3 = 57

If you want to remember the shortcut; PEMDAS

P  - Parentheses first

E  - Exponents (Powers and Square Roots, etc.)

MD  - Multiplication and Division (left-to-right)

AS  - Addition and Subtraction (left-to-right)

Remember that:

Divide and Multiply rank equally (and go left to right).

Add and Subtract rank equally (and go left to right)

Answer:

[tex]f(g(x)) = \frac{10x-9}{3 + 3x}[/tex]

Step-by-step explanation:

Given

[tex]f(x) = \frac{1}{x} - 3[/tex]

[tex]g(x) = \frac{3}{x} + 3[/tex]

Required

Find f(g(x))

If: [tex]f(x) = \frac{1}{x} - 3[/tex]

Then:

[tex]f(g(x)) = \frac{1}{3/x + 3} -3[/tex]

Solve the denominator (take LCM)

[tex]f(g(x)) = \frac{1}{\frac{3+3x}{x}} -3[/tex]

[tex]f(g(x)) = \frac{x}{3 + 3x} - 3[/tex]

It can be solved further as:

[tex]f(g(x)) = \frac{x-3(3 + 3x)}{3 + 3x}[/tex]

[tex]f(g(x)) = \frac{x-9 + 9x}{3 + 3x}[/tex]

[tex]f(g(x)) = \frac{10x-9}{3 + 3x}[/tex]

Answer:

Sum = 140

Step-by-step explanation:

We find all the terms, we know that every consecutive term, we add 2 until we reach 23:

Sum = 5 + 7 + 9 + 11 + 13 + 15 + 17 + 19 + 21 + 23

Sum = 140

Answer:

x=43

Step-by-step explanation:

complementary angles will add up to equal 90 so we set up an equation to solve x

12+x+25=90

step 1 combine like terms

12+25=37 so now its

37+x=90

step 2 we subtract each side by 37

90-37=43

x=43

hope this helps and have a great day :)

Answer:

53°

Step-by-step explanation:

Complementary angle = 90°

So, 12° + (x+25°) = 90°

Subtract 12 from both sides

x+25°=78°

Subtract 25 from both sides

x=53°

1. The entire fraction is negative if the numerator or denominator are negative.

if both parts of the fraction were negative, the entire fraction would be positive (- / - = +)

2. Of course, although most teachers ask you to put the negative sign in the fraction as a whole (before the fraction line) or in the numerator. never leave a fraction with two signs. in this case, if it has two signs and they are different, the whole fraction is NEGATIVE

3) No. the whole fraction is POSITIVE only if both the numerator and the denominator have the same sign, + + or - -

The required difference in the expression (f – g)(x) is - 6x³+ 4x² + 4x - 8

Given the following functions

f(x) = 2x² + 4x - 5

g(x) = 6x³ – 2x² + 3

In order to get the required function (f-g)(x), we will have to take the difference of the function as shown:

(f – g)(x) = f(x) - g(x)

Substitute the given parameters into the expression

(f – g)(x) = 2x² + 4x - 5 - (6x³ – 2x² + 3)

Expand

(f – g)(x) = 2x² + 4x - 5 - 6x³ + 2x² - 3

Collect the like terms

(f – g)(x) = 2x²+2x²- 6x³ + 4x -5 -3

(f – g)(x) = - 6x³+ 4x² + 4x -5 -3

(f – g)(x) =  - 6x³+ 4x² + 4x - 8

Hence the required difference in the expression (f – g)(x) is - 6x³+ 4x² + 4x - 8
