Answer:

$\huge \colorbox{red}{ \rm (3x - 7)(x + 1)}$

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>

factoring
PEMDAS

<h3>tips and formulas:</h3>

quadratic expression:ax²+bx+c

factoring quadratic:

Find two numbers that multiply to give ac, and add to give b
rewrite the middle with those numbers
factor out common terms
group

<h3>let's solve:</h3>

a is 3 and b is -7

$\quad ac=3\times -7$

therefore

$\quad ac=-21$

now we need to find two numbers that give -21

to do so we need to find the factors of 21

which are

$\quad 1,3,7$

likewise,

$\quad -1,-3,-7$

in this case we can take any two numbers from negative and positive factors that give us -21 and -4

3 and -7 are the two numbers that multiply to give -21 (3×-7=-21) and add to give -4. (3+(-7)=-4)

now let's factor:

$\sf rewrite \: - 4x \: as \: 3x - 7x : \\ \rm {3 x}^{2} + 3x - 7x - 7$
$\sf factor \: out \: 3x : \\ \rm 3x(x + 1) - 7x - 7$
$\sf factor \: out \: - 7 : \\ \rm 3x(x + 1) - 7(x + 1)$
$\sf \quad group : \\ \quad \rm (3x - 7)(x + 1)$

$\text{And we are done!}$

Answer:

6 chocolates

Step-by-step explanation:

If there was 2 chocolates left and he had just eaten a third that would mean he had eaten 1

That would mean there would have been three chocolates before he put away the groceries

Double that to make up for the chocolates eaten during the walk home = 6

Evaluate the expression if m = − 4 , n = 1 , p = 2 , q = − 6 , r = 5 , and t = − 2 | 16 + 4 ( 3 q + p )

Arisa [49]

The evaluation of the expression, if m = − 4 , n = 1 , p = 2 , q = − 6 , r = 5 , and t = − 2 | 16 + 4 ( 3 q + p ) is 46.

<h3>How can the expression be simplified?</h3>

the given expression is t = − 2 | 16 + 4 ( 3 q + p )

Then since we are given m = − 4 , n = 1 , p = 2 , q = − 6 , r = 5

Then, we can substitute all the given values of the terms into the given expression as :

t = − 2 | 16 + 4 ( 3 q + p )

t= -2 I 16+4(-18+2)

t= -2 I 16+4(-16)

t= -2 I 16 -64

t= -2 I -48

t =46
