Answer:

Only 2 and -5 are roots. Any other number is not a root.

Step-by-step explanation:

The zeros of the function are the x-intercepts and are found by factoring the equations and solving for x using the zero product property.

The f(x) = (x2 - 4x + 4) (x2 + 3x - 10) = 0 can factor into

f(x) = (x -2)(x-2)(x+5)(x-2) = 0.

Set each factor equal to 0 and solve.

x - 2 = 0 so x = 2. This repeats twice.

x + 5 = 0 so x = -5.

So the zeros are 2, -5.

Is anyone good at paralleligram?!I will mark brainlest.for 13 points​
Black_prince [1.1K]

Answer:

Y= 15

x = 12

Step-by-step explanation:

Okay, so the sides that are across from eachother, are always equal to eachother, in a parallelogram.

So, 5y-20 = 2y + 25

Next, you add 20 to both sides, and then subtract 2 from the right side, and subtract 2 from the left side ,and you get 3y = 45

divide 45 by 3 , and you get 15.

DO the same thing for the X's.

Paguei 74,00 por uma bolsa e uma sandália. A bolsa foi 23,00 mais barato q a sandália. Qual o preço da sandália?
alukav5142 [94]

Responda:

48,5

Explicação passo a passo:

Dado que:

Custo total de bolsa e sandália = 74,00

Deixei :

Custo da sandália = x

Custo da bolsa = x - 23

Preço da sandália:

x + (x - 23) = 74

x + x - 23 = 74

2x - 23 = 74

2x = 74 + 23

2x = 97

x = 97/2

x = 48,5

Portanto, custo da sandália, x = 48,5

Is the square root of 12 rational or irrational?
Andreyy89
<h3>Answer: Irrational</h3>

We cannot write sqrt(12) as a fraction of two whole numbers

Note how sqrt(12) = 3.464 and the decimal portion goes on forever without any known pattern (and it doesnt repeat either).

Compare this to something like sqrt(16) = 4 which can be written as a fraction 4/1, so sqrt(16) is rational
