Again this is a simple addition problem I think.
Add 3.6+4.705+5.92=
14.225 kilometers that Andrea ran over the three days.
Hope this helps, have a good day. c;
The y intercept is when x=0 so y=1/2(0) -3 so y=0-3 so y=-3
Answer:
5
Step-by-step explanation:
= 3.87
= 8.25
Integers between the two:
4, 5, 6, 7, 8
5 numbers in total
Answer:
8 blocks left, 6 blocks up.
Step-by-step explanation:
Remember the acronym of NESW (North, East, South, West). I remember it as Never Eat Shredded Wheat. If you go 6 blocks up, and 8 blocks left, you would be 8 blocks left, and a little down.

Answer:
x = - 4 , x = - 3
Step-by-step explanation:
- 7x = x^2 + 12
Take all terms to one side of equation.
x^2 + 7x + 12 = 0
Find which 2 numbers multiply to give 12 and add to give 7.
a × b = 12
a + b = 7
a = 4
b = 3
Split the middle term using these 2 numbers.
x^2 + 4x + 3x + 12 = 0
Factorise each pair of terms separately.
x ( x + 4 ) + 3 ( x + 4 ) = 0
Bring out common factor of ( x + 4 ) and factorise.
( x + 4 ) ( x + 3 ) = 0
Using the Null factor law, make the expressions in each pair of parentheses equal 0.
x + 4 = 0
x = - 4
AND
x + 3 = 0
x = - 3
THEREFORE:
x = - 4 , x = - 3
