\sf Hello!

\sf y = 2x^{2} + 4x - 3

\sf Discriminant :

= \sf b^{2} - 4ac

= \sf (4)^{2} - 4.(2).(-3)

= \sf 16 - (-24)

= \sf 16 + 24 = \sf 40

\sf Since,
\sf D \:is\:Greater\: than\: 0.

\sf Roots\: are\: Real\: and\: Distinct

\sf Hence,

\sf y = 2x^{2} + 4x - 3\: have\: A.\: Two\: real\: roots

The sun of three conservative integers is -204. what is the largest integer?
Digiron [165]

let us take the smallest integer as x

the second smallest as x+1

and the largest as x+2

since the sum is -204 we should add all of it to get the answer

therefore x+x+1+x+2=-204

3x+3=-204

3x=-204-3

3x=-207

x=-207/3

x=-69

the largest number is x+2

therefore the largest number is -67

to check whether it is right just add them and check whether we get - 204

therefore -69+-68+-67=

-204

therefore the answer is -67

There is a rectangular terrain with dimensions "x" and "y". If it is known that its area of ​​is 22m ^ 2 and that x ^ 2 + y ^ 2
Margaret [11]

9514 1404 393

Answer:

  24 m

Step-by-step explanation:

The area formula tells us ...

  22 = xy . . . . . square meters

Adding twice this to the quadratic constraint gives ...

  (x^2 +y^2) +2(xy) = (100) +2(22)

  (x +y)^2 = 144

  x +y = √144 = 12

The perimeter is double this amount, so is ...

  P = 2(x +y) = 2(12) = 24 . . . . meters

Answer the question below. Type your response in the
lukranit [14]
<h3>Answer: 31 degrees</h3>

This is because rotations preserve angles. The angle measures won't change. That's why angle BCD is the same as angle B'C'D'. This applies to any rotation (regardless how much you rotate), any translation, any reflection, and any dilation.

Note: dilations will change the side lengths
