Answer:
2x + 3 )(x + 2 )
Step-by-step explanation:
2x² + 7x + 6
Find two numbers multiplied together to get 6
and if you multiply one by 2, the answer is 7:
Tested:
6 & 1 but 6 · 2 + 1 = 13 or 6 + 2 · 1 = 8 No
2 & 3 and 2 · 2 + 3 = 7 Yes
2x² = 2x & x
all signs are positive
trinomial factoring ( )( )
( + )( + )
2 and 3 are the numbers to use (2x + 3 )(x + 2 ) or (2x + 2) (x + 3)
The largest number goes with the 2x.
Therefore (2x + 3 )(x + 2 )
Check 2x(x + 2) + 3(x + 2)
2x² + 4x + 3x + 6
2x² + 7x + 6 checked

Answers in step-by-step.
Step-by-step explanation:
We are going to make Sarah the variable "s."
Using the given information, the following equation is derived to calculate Sarah's distance.
And the following equation will be used to calculate what Sarah collected using "p" for pledged money.
If Sarah collected $450 in pledges, we can use the preceding formula to calculate her distance.
- P=18S
- 450=18S
- 450/18=S
- 25 miles = S
Using Sarah's distance, we can calculate Semir's either the first equation.
- S=2n-5
- 25=2n-5
- 30=2n
- 15=n
- Semir walked 15 miles.
We already found Sarah's distance to be 25 miles.
Now SungSo is making the same amount as Sarah. He collects $450 total, but he got $72 from his grandmother initially, so subtract 72 from 450 to get the amount he collected from walking.
His formula is the same as Sarah's, but we'll use SS for his variable.
- P=18SS
- 378 = 18SS
- 378/18=SS
- 21= SS
- SungSo walked 21 miles.
Answer:
-58
Step-by-step explanation:
6 (10 - 23) + 20
=6 x (10 - 23) + 20
= 6 x (- 13) + 20
= -78 + 20
= -58
