How to simplify the expression (x+4)*(3x+5)

Mathematics

You use PEMDAS.

First, parentheses
(x+4) = 4x
(3x+5) = 3x+5

So, that is
4x*3x+5

Then, exponents. We don’t have any.

Then, multiplying.

4x*3x is 12x

So, 12x+5

And then, division. We don’t have anything to divide.

Then, addition and subtraction

You can’t add the variable to a number, so the answer is just

12x+5.

Hope it helped. :)

because 114 pages are already read and if he needs 333 pages to reach 1/3 of the book you add 114 and 333 so you can find out how much pages is 1/3 of the book. then you multiply that number by 3 because there are 3 sections of 333+114.

Solve the equation I will give brainly ​
Alika [10]

Answer:

answer: All real numbers, or No solutions

Step-by-step explanation:

okay, the equation says 4(x+4)=(4x+16)

if we apply 4 to the parenthesis we get 4*(x+4)=4x+16

so basically the equation is telling us 4x+16=4x+16, which gives us all real numbers or No solutions as the answer

Factorise 14e-16<br> Please explain
rosijanka [135]

The expression 14e - 16 is an algebraic expression, and the factored expression is 2(7e - 8)

<h3>How to factor the expression 14e - 16?</h3>

The expression is given as:

14e - 16

Express both terms as a product of 2

14e - 16 = 2 * 7e - 2 * 8

Factor out 2 in the expression

14e - 16 = 2 * (7e - 8)

Remove the product sign

14e - 16 = 2(7e - 8)

Hence, the factored expression of 14e - 16 is 2(7e - 8)
