X squared plus 10x plus 9 equals 0

Mathematics

snow_lady [41]3 years ago

That is a quadratic equation. To find its square, think of two numbers that when multiplied, the answer would be the last term, constant 9 and if those two numbers are added, the answer would be the middle term, the constant 10 with variable x. These are positive integers 9 and 1, respectively.

(x² + 10 x + 9) = 0
= (x + 9 ) (x + 1)

Using the FOIL method to check, the square is equal to the quadratic equation.

There are 70 questions. The probability of getting any one of the questions right is 0.2. That's because there are five answers only one of which is correct.

If there are 5 questions and you want to pick the right one the probability is 1/5. If you don't know how to find that, let your calculator walk you to the answer.

1
÷
5
=
And it will tell you that it is 0.2.

So if you blindly (not brainly) fill in the multiple choice answer sheet, the number you will get right is
(P(0.2) * The total number of questions or
0.2 * 70 = 14
Just pure dumb luck will give you 14 correct answers.

Michael and Kathryn bowl together and their combined total score for one game was 425points. Michael’s score was 70 less than tw
In-s [12.5K]

Hey there!

Let us take Michael's score as ' x '

Let us take Kathryn's score as ' y '

Michael - 70 less than twice Kathryn's


x = 2y - 70

y = y

Add them, we get , 425

2y - 70 + y = 425

3y - 70 = 425

3y = 495

y = 495/3

y = 165

Kathryn's score = 165

Michael - 2 ( 165 ) - 70

= 260

Hope it helps!
