Answer:
x1 = -4.872983346
x2 = 2.872983346
Step-by-step explanation:
Given:
x^2+2x+7=21
Subtract 21 on both sides to get the right side equal to 0:
x^2+2x-14=0
Use the quadratic formula:
x1 = -4.872983346
x2 = 2.872983346

simplify 20 divided by 4+6.2 HURRY
Answer:Your answer is 2, hope my answer helped!
Step-by-step explanation:
The simplified value of 20 divided by 4+6.2 is approximately 1.96. This means that if we add 4 and 6.2 to get 10.2, then divide 20 by 10.2, the result is approximately 1.96.
To simplify the expression 20 divided by 4+6.2, we need to perform the addition first, and then perform the division.
First, let's evaluate 4 + 6.2:
4 + 6.2 = 10.2
Now, we have 20 divided by 10.2:
20 / 10.2 = 1.96078...
Rounded to a reasonable number of decimal places, the result is approximately 1.96.
Therefore, the simplified value of 20 divided by 4+6.2 is approximately 1.96. This means that if we add 4 and 6.2 to get 10.2, then divide 20 by 10.2, the result is approximately 1.96.

Just some simple fraction problems, I am stuck on this though.
Answer:
5 1/6 ÷ 4 2/3 = 31/28
3 3/4 ÷ 1 2/8 = 3
4 2/4 ÷ 2 1/4 = 2
5 2/5 ÷ 1 4/5 = 3
4 2/8 ÷ 3 2/4 = 17/4
3 3/9 ÷ 2 4/12 = 10/7
7 1/2 ÷ 3 3/5 = 25/12
6 2/8 ÷ 3 1/3 = 15/8
Explanation:
5 1/6 ÷ 4 2/3 = 31/6 ÷ 14/3 = (31/14) / (6/3) = (31/14) / 2 [when you divide by a certain number you multiply that number by the denominator] = 31/28
5 1/6 ÷ 4 2/3 = 31/6 ÷ 14/3 = 31/6 × 3/14

Hey y’all. I’m so embarrassed and I want to hit my head so BAD:( I’m literally crying. So I had a test in math and I’ve always been cheating and I was the best math student but when the class was gonna end I told the teacher I only have two questions and she told me to still stay and when I finished the submit button didn’t work and the teacher told me to present my screen and I did but when I did the teacher face wasn’t happy because when I showed her my screen in the tabs I had tabs that help me cheat the test. But the teacher didn’t tell me anything and she told me that if I have the notes for all my questions answers and I didn’t know what to say so I said yes! But I told her if I should take pictures of the answers and she said no. And I started panicking so she told me to reload the WHOLE THING so I did and all my 18 questions answers deleted and I told the teacher I had to go to my other class and she said bye. I’m literally crying. I’m hitting my head so hard. Karma is real:( F

If ΔJKL~ΔMKN, find the value of x.
Answer:
x = 14
Step-by-step explanation:
Since the triangles are similar, then the ratios of corresponding sides are equal, that is
[tex]\frac{KL}{KN}[/tex] = [tex]\frac{JL}{MN}[/tex] , substitute values
[tex]\frac{32}{12}[/tex] = [tex]\frac{3x-2}{x+1}[/tex] ( cross- multiply )
12(3x - 2) = 32(x + 1) ← distribute parenthesis on both sides
36x - 24 = 32x + 32 ( subtract 32x from both sides )
4x - 24 = 32 ( add 24 to both sides )
4x = 56 ( divide both sides by 4 )
x = 14
