Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about:</h3>
<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

therefore

now we need to find two numbers that give -21
to do so we need to find the factors of 21
which are

likewise,

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:





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
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

Answer:
34
Step-by-step explanation:
Points B,C,D, and E are points on the edge of the circle.
and
are in the same segment.
We have that: 
We want find 
Recall that angles in the same segment are congruent.

So the answer is 34
