The simplified form of the expression 7^x+1 + 7^x / 2×7^x as given in the task content follows from the laws of indices and is equal to; 4.

<h3>What is the simplified form of the expression 7^x+1 + 7^x / 2×7^x?</h3>

It follows from the task content that the expression whose simplified form is to be determined is given as; 7^x+1 + 7^x / 2×7^x.

On this note, it follows from the law of indices that; 7^x+1 = 7× 7^x.

Hence, we have; 7^x(7+1 ) / 2×7^x.

And upon simplification, we have; 8/2 = 4.

Consequently, we may conclude that the simplified form of the expression as given in the task content is; 4.

Given that f(x) = x2 – 3x – 28 and g(x) = x - 7, find
gregori [183]

Answer:

(f-g)(x)=x^2-4x-21

Step-by-step explanation:

We are given the two functions:

f(x)=x^2-3x-28\text{ and } g(x)=x-7

And we want to find:

(f-g)(x)

This is equivalent to:

=f(x)-g(x)

Substitute:

=(x^2-3x-28)-(x-7)

Distribute:

=x^2-3x-28-x+7

Rearrange:

=(x^2)+(-3x-x)+(-28+7)

Hence:

(f-g)(x)=x^2-4x-21

PLZ help Asap!!!!!!!!!!!!!!!!!!!!!!!
maria [59]
I'm may not be that good at math, but I'm going to try my best to help you, because I know how it feels to be in this situation! 

The first one : 
You might be right on D. But I'm thinking B also. The question asks "Which could be a cross section of a rectangular pyramid that has been intersected by a plane perpendicular".  But a triangle is basically a flat pyramid. 

(I'm typing really fast to help!!!!) 

Second one: Its B!! Look at it really closely! You'll get it!!!

(Going really fast now!!!!) 

Third one: Between B or D!!! But I think you're right on your choice!!!!

(FASTER FASTER!!!) 

FINALLY: Copy and paste your answers into google. People have asked the same question! 

I hope I helped. I don't want to make you fail, as I am in the SAME similar situation as you! I really REALLY REALLY HOPE YOU PASS!!!
