It appears that none of your option choices are correct,, are you sure you copied them right ? I will show you how to solve this and how I got my answer.
The first step for solving this is to add the numbers in the parenthesis.
3 × 11 × 2 - 14 ÷ 7
Divide -14 by 7.
3 × 11 × 2 - 2
Divide the first 3 numbers together.
66 - 2
Subtract the numbers together to get your final answer.
64
Let me know if you have any further questions.

Answer:

361

Step-by-step explanation:

3(7 + 4)² − 14 ÷ 7

3(11)² -- 14 ÷ 7

3(121) - 14÷7

363 - 2

= 361

took the test and got a 100 btw

How to graph 6x + 3y = 12
explanation:

Step 1: Find x intercept: substitute 0 for y: solve for x

• 6x + 3(0) = 12
• 6x = 12
• x = 2

Step 2: Then Find y intercept: also substitute 0 for x; solve for y

• 6(0) + 3y = 12
• 3y = 12
• y = 4

So plot x and y intercepts: ( 2,0 ) and ( 0,4 ) then draw a line through the points.

How to graph 3x + y = 5
explanation:

Step 1: Find x intercept: substitute 0 for y: solve for x

• 3x + 5(0) = 15
• 3x = 15
• x = 5

Step 2: Then Find y intercept: also substitute 0 for x; solve for y

• 3(0) + 5y = 15
• 5y = 15
• y = 3

plot x and y intercepts: (5,0 ) and ( 0,3) then draw a line through the points.

Hope this help:))

(ASAP)<br> Solye for n.<br> 24 = 3(n – 5) <br> n=
Paul [167]

Answer: can u check out the image cuz the answer is in the photo and hope this helps can u give me brainliest

Step-by-step explanation:

24=3(n-5)

Distribute.

24=3(n) + 3(-5)

24 = 3n -15

Add 15 to both sides.

39 = 3n

Divide both sides by 3.

n = 13.

I hope this helps!.

If f(x) = -2x + 4, then f^-1(x) =
Nadusha1986 [10]

Answer:

f^{-1}(x) = -\frac{x}{2} +2

Step-by-step explanation:

Consider the real number y such that  f ⁻¹(x) = y

f^{-1}\left( x\right)  =y\Longleftrightarrow f\left( y\right)  =x

We need to find y in order to determine the expression of  f ⁻¹(x)

f(y) = x ⇔ -2y + 4 = x

⇔ 4 - x = 2y

⇔ y = (4 - x)/2

\Longleftrightarrow y=-\frac{x}{2} +2
