What are the coordinates of the root of the equation x^2+4x+3=0

Mathematics
1 answer:
Alla [95]3 years ago
3 0

Answer:

(- 3, 0) and (- 1, 0)

Step-by-step explanation:

Given

x² + 4x + 3 = 0 ← in standard form

(x + 1)x + 3) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 1 = 0 ⇒ x = - 1

x + 3 = 0 ⇒ x = - 3

coordinates of the roots are (- 3, 0) and (- 1, 0)

SOMEONE PLEASE ANSWER AND I WILL GIVE BRAINLIEST :))A company makes poppy lapel pins. Each of them costs £1.10 to make. In Octob
Liono4ka [1.6K]

Answer: The company will make 720 dollars (I dont know the percentage out of that though).


Step-by-step explanation: 1.10 times 1000= 1100. 35 percent of that is 385 dollars worth to charity or 350 lapel pins. 1000 minus 350 equals 650. 650 times .6 equals 390. 390 times 3 dollars= 1170 dollars. 650 times .4 = 260. 260 divided by 2 = 130, 130 times 5 dollars equals 650 dollars. 650 plus 1170= 1820. 1820-1100= 720.

Last Question

Because this may not be the question you want, I'll omit the first step which should be done with latex. The key to all of these except C is to invert the second fraction (turn the second fraction upside down) and multiply.

A

\dfrac{6}{5} * \dfrac{-2}{3}

=(6*-2) / (5*3) = - 12/15 = -4/5

B

\dfrac{7}{4} *\dfrac{5}{3}

= (7*5) / (4*3) = 35 / 12 = 2 11/12

C

Impossible to do 4/0 cannot be done.

D

\dfrac{-2}{3} /\dfrac{-5}{4}=\dfrac{-2}{3} *\dfrac{-4}{5}

= (-2*-4)/(3*5) =

8/15

Lenny is planning to cut down a pine tree. He has parked his truck 90 feet away from the base of the tree and wants to make sure
Veronika [31]

Well, if the elevation is 45 degrees, the height of the tree and the distance to the truck are the same.


The elevation is more than that, so the distance to the truck is less than the height of the tree. 


The only answer that reflects that is D.
