Simplify (3x+2)(x-7)
vovangra [49]
The answer is
3 {x}^{2}  - 19x - 14
first you must multiply or use the FOIL method (First, Outer, Inner, Last)
First you multiply the first terms
(3x)(x)
this gives you 3x^2, then you multiple the outer terms
( - 7)(3x)
this gives you -21x, then you multiply the inner terms
(2)(x)
that gives you 2x, finally you multiply the last terms
(2)( - 7)
that gives you 14, now you combine like terms
- 21x + 2x =  - 19x
now you put all the terms together and end up with your solution
3 {x}^{2}  - 19x - 14

Answer:

  yes

Step-by-step explanation:

You can go at this a couple of ways:

1. The total length David needs is (1.75 m) × 4 = 7.00 m. His 7.28 m piece is long enough to provide the pieces he needs.

__

2. The length of each piece when the wood is cut into quarters is ...

  (7.28 m)/4 = 1.82 m

This is longer than the 1.75 m needed, so each piece is long enough.

kotykmax [81]

Answer:

The Possibilies is given below.

Step-by-step explanation:

Given Amber's bank statement shows a closing balance of $224.13. There are no outstanding checks or deposits. Her checkbook shows a balance of $221.38.

The difference in amount i.e $224.13-$221.38=$2.75
