Zero real solutions I just did the test

Discriminant D is given by:
D=b²-4ac
Implication of discriminant is as follows:

D<0 two zeros that are complex conjugate
D=0 one real zero of multiplicity 2
D>0 two distinct real zers
D= (+ve perfet square) two distinct rational zeros
From:
12x^2+10x+5=0
plugging in the equation we get:
10²-4×12×5
=100-240
=-140
thus
D<0

Answer is:
A two irrational solutions

How do I find the ratio of this? It makes no sense to me

Volgvan

Answer:

$\frac{169}{289}$

Step-by-step explanation:

Given 2 similar figures with ratio of sides = a : b, then

ratio of areas = a² : b²

Here ratio of sides = 52 : 68 = 13 : 17 ← in simplest form, thus

ratio of areas = 13² : 17² = 169 : 289 = $\frac{169}{289}$

Which expression does not factor? m3 + 1 m3 – 1 m2 + 1 m2 – 1

Luda [366]

Answer:

$m^2 +1$

Explanation:

All the other expressions can be factorized. Let's see why:

1) $m^3 +1$

This is the sum of the cubes, and this can be factorized as follows:

$a^3+b^3=(a+b)(a^2-ab+b^2)$

In this case, a=m and b=1, so we can factorize as

$m^3+1=(m+1)(m^2-m+1)$

2) $m^3-1$

This is the difference between two cubes, and this can be factorized as follows:

$a^3-b^3=(a-b)(a^2+ab+b^2)$

In this case, a=m and b=1, so we can factorize as

$m^3-1=(m-1)(m^2+m+1)$

3) $m^2-1$

This is the difference between two square numbers, and it can be factorized as follows

$(a^2-b^2)=(a+b)(a-b)$

In this case, a=m and b=1, so we can factorize as

$m^2-1=(m+1)(m-1)$

Someone help with this question ?????? Hi

8090 [49]

ANSWER

The second statement is the contrapositive of the first.

EXPLANATION

If we have the conditional statement,

$x\Rightarrow \: y$

Then the converse of this statement is
$y\Rightarrow \: x$

The inverse of this statement is
$\neg \: x\Rightarrow \neg \: y$

and the contrapositive of this statement is
$\neg \: y\Rightarrow \neg \: x$

The correct answer is C.
