Answer:
Step-by-step explanation:
The given quadratic equation is expressed as
x² - 12x + 36 = 90
Rearranging it in line with the standard form of ax² + bx + c, it becomes
x² - 12x + 36 - 90 = 0
x² - 12x - 54 = 0
The general formula for solving quadratic equations is expressed as
x = [- b ± √(b² - 4ac)]/2a
From the equation given,
a = 1
b = - 12
c = - 54
Therefore,
x = [- 12 ± √(- 12² - 4 × 1 × - 54)]/2 × 1
x = [- 12 ± √(144 - - 216)]/2
x = [- 12 ± √360]/2
x = (- 12 + 18.97)/2 or x = (- 12 - 18.97)/2
x = 3.485 or x = - 15.485
Answer:
infinite solutions

m can be any number
Y = 32
Can I get brainliest I do not have a rank
First problem:
The answer is C because theoretically it should have a 50% of landing
heads but instead it lands heads 56% of the time. Thus this is 6% higher
than 50%. It's not D because there is not specified detail of how the
person got this data so you can assume that the person did a fair
survey/data collection.
Second problem:
So in a data size of 490, 140 of them we trout. This means that 140/490 or 28.57% of the fish are trout. This means that in a sample size of 5000 fish, 5000*0.2857 or 1428.57 are trout.
Third problem:
The Science students seem to have a higher average score because the average score of Math students are:
(32+33+34+34+35+37+39+40+40)/9=36
average score of Science students are:
(41+42+43+43+46+46+47+49+49)/9=45.111
You gotta list the whole problem we can figure out how old Jackie and Danny is unless there is more text in the problem for example: If Danny is old than Jackie by 1 year and Jackie is older than Ronny by 10 years how old is Jackie and Danny.
