Answer:
5+√97/4
Also 5-√97/4
Step-by-step explanation:
The Quadratic formula is x=-b+-√b^2-4ac/2a
This means that we should plug the values for A B AND C into the formula
We can work out that
<u><em>A = 2</em></u>
<u><em>B=-5</em></u>
<u><em>C=-9</em></u>
Once we have put these into the formula we get
5+√97/4 (all over 4) aka 3.71
Also 5-√97/4 (all over 4) aka -1.21
Answer:
a°=45°
Step-by-step explanation:
SOLUTION,
→a°=45°[ Being alternate angles]
→Hence,a°=45°
Answer:
2x^3-23y^2+72-128
Step-by-step explanation:
its like when you just do two
do the first 2 first
(y-8)(y-8)
this is (y^2 -8y+y^2+16) simplify (2x^2-7y+16)
then add the other bracket
(2x^2-7y+16) (y-8)
2x^3-16x^2-7y^2+56y+16y-128 simplify
Answer:
x-30
Step-by-step explanation:
Firstly, you do the first step, which is, 3x-18+4x+12-6x, then you continue simplifying it: 7x-18+12-6x.
Keep it on and on, the next step: x-18+12, add 18 and 12 together you get 30.
So the final answer is x-30
