5.65 in decimal and 113/20
65x^2 + 212x - 133
you have to use the quadratic formula
x=( -b +/- √b²-4ac) / 2a
a is 65
b is 212
c is 133
because the first value is squared you will have 2 answers
x= 7/13
x= - 19/5
Answer:
<h3>(-4, 1)</h3>
Step-by-step explanation:
-x-3=y, therefore x = -y-3
-3x - 8y = 4
Find the value of y
Substitute the x in -3x - 8y = 4 with -y-3
We get
-3·(-y-3) - 8y = 4
3y + 9 - 8y = 4
-5y = 4-9
-5y = -5
<h3>y = 1</h3>
_______________
Find the value of x
x = -y-3

Answer:
14
Step-by-step explanation:
We can find the sum of these numbers by adding them together.
The cumulative rule of addition lets us add numbers together in any order we want.
So, for 2 + 3 + 4 + 5 …
2 + 3 = 5
So now we have 5 + 4 + 5
5 + 4 = 9
Now we have 9 + 5
And 9 + 5 = 14
So, your answer is 14
Hope this helps!
