(2x² + 7x + 10) - (x² + 2x - 9) =
2x² + 7x + 10 - x² - 2x + 9 =
x² + 5x + 19
Answer:
x=1
Step-by-step explanation:
To solve this question we will have to open the bracket first
So let's solve the question
5(2x-8)+15=-15
Bracket first
10x-40+15=-15
We will have to solve the question further
10x-25=-15
Add 25 to both sides
10x=10
Let's make x the subject of formula by dividing both sides by 10
x=1
Therefore x is 1
Answer:

it is very simple, is you are given the co-ordinates for the graph plot them.
Answer:
$3.7625
Step-by-step explanation: I may be wrong but...
If you find 75% of $2.15 it is equal to $1.6125.
Since in "increases" we are going to add $1.6125 to $2.15.
You get the answer of $3.7625.
