What is 5(x + 6)+11 =25 3x
1 answer:
Answer:
x=
Step-by-step explanation:
5(x+6)+11=25
Use the distributive property to multiply 5 by x+6.
5x+30+11=25
Add 30 and 11 to get 41.
5x+41=25
Subtract 41 from both sides.
5x=25−41
Subtract 41 from 25 to get −16.
5x=−16
Divide both sides by 5.
x=-16/5
Fraction -16/5 can be rewritten as -16/5 by extracting the negative sign.
x =

Answer: 4095
<u>Step-by-step explanation:</u>
He sold 1 car on the first day so the first term (a) is 1. The amount doubles each month so the ratio (r) is 2.
Input those values into the Sum formula:
The factors of this polynomial would be (x + 4)(x + 2)(x - 1).
To find these, you first have to start with long division to find the first factor. If you use x + 4 it would look like this.
=
Now we are left with only . We can factor this by looking for numbers that multiply to the last number and add to the middle number. 2 and -2 multiply to -2 and add to 1. Therefore, we'll use those in parenthesis in their place.
(x + 4)(x + 2)(x - 1)
