A. 34
B. 18
C.65

Answers

Answer 1

Answer:

A.34

Step-by-step explanation:

f(4)=17

2f(4)=34

if I've understood it :/ but I've didn't understood about g(x)

Answer 2

Answer:

A. 34

Step-by-step explanation:

f (x) = x² + 1. f (4) simply means we should replace X with 4

so it will be

f (4) = 4² + 1

= 16 + 1

= 17

so now 2. f ( 4) means:

2. 17

which gives :

34

hope this helps

1. Choose the word that is defined as: Symbols used to represent
unspecified numbers.
Factor
Term
Variable
Power
O Algebraic Expression

Answers

Answer:

I think the first one is the best answer but you might be expected to say variable. I cannot choose one answer. It all depends what you have been told or what your teacher has said about it.

Myself, I would pick A.

Step-by-step explanation:

Symbols (like letters) that are used to represent numbers which are unspecified.

The problem is that variable is also a possible answer. The problem is that a variable is usually a letter. Symbols do are not used for variables in anything but counting systems.

When you look up the word variable it is defined as a symbol. But that is too confining.

pretty sure this is algebra

A triangle has side lengths of 2x , x + 4, and 3 (x + 3). Find the value of x if the perimeter of the triangle is 55 inches.​

Answers

Answer:

x=7

Step-by-step explanation:

55=2x+(x+4)+[3(x+3)]

55=2x+x+4+3x+9

55=6x+13

55-13=6x

42=6x

7=x

Answer:

7 inches

Step-by-step explanation:

Perimeter is the sum of side lengths:

P = 2x + x + 4 + 3(x + 3)P = 55

Solve for x:

2x + x + 4 + 3(x + 3) = 553x + 4 + 3x + 9 = 556x + 13 = 556x = 55 - 136x = 42x = 42/6x = 7

If de=4x+10 Ef=2x-1 and df= 9x-15 find df

Answers

Step-by-step explanation:

Assuming that de + ef = df, we can create the expression:

(4x + 10) + (2x - 1) = 9x - 15

Combine like terms to get:

6x + 9 = 9x - 15

The rest is basic algebra after this point.

6x + 9 = 9x - 15

-6x +15 -6x +15

______________

24 = 3x ----> x = 8

Next, plug the x value into the df equation to find df.

df = 9(8) - 15

df = 72 - 15

df = 57

If m ZABD = 83º, what are mZABC and m ZDBC?
3x+33° D
(Ex-6)°
B
mZABC = °

Answers

Answer:

∠ ABC = 48°

Step-by-step explanation:

∠ ABC + ∠ DBC = ∠ ABD , that is

6x - 6 + 3x + 8 =  83

9x + 2 = 83 ( subtract 2 from both sides )

9x = 81 ( divide both sides by 9 )

x = 9

Then

∠ ABC = 6x - 6 = 6(9) - 6 = 54 - 6 = 48°

Answer:

23. Congruent

24. Not congruent

Step-by-step explanation:

23. KJ and HL:

Since the side lengths are both 4 in, these segments are congruent.

24. EH and FG:

Since the side lengths are different numbers (0.45 cm and 0.5 cm), these segments are not congruent.

The answer is KJ and HL. Only the first one is congruent because both lines EH and FG don’t have sides with equal measurement.

Name the marked angle ( < KLI ) in 2 different ways

[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]

You can name the angle as < ILK too.Why? Well, to name an angle you only need to focus on keeping the vertex of the angle (the middle point where the angle gets formed) in the middle while naming. In this case the vertex is L. Then you can just shift the places of the 2 arms of the angle ( I & K ) & yea, then you'll get the name of the angle as < ILK.
