Answer:

1/((x+3)*(x+1))

Step-by-step explanation:

We can write the expression as:

((x-2)/(x^2+x-6))/((x^2+5*x+4)/(x+4))

We can write the term as a single division by multiplying the terms in numerator by the inverse on the terms in the denominator:

((x-2)/(x^2+x-6))*((x+4)/(x^2+5*x+4)/)

((x-2)*(x+4))/((x^2+x-6)*(x^2+5*x+4))

We can simplfy the denominator terms as:

x^2+x-6=(x+3)*(x-2)

x^2+5*x+4=(x+4)*(x+1)

Therefore (x-2) and (x+4) in the numerator and denominator cancels out and we are left with:

1/((x+3)*(x+1))

X-2 over x2+x-6 divided x2+5x+4 over x+4 requires 2 factoring, canceling like factors, and inverting the divisor and multiplying.

(x-2) over (x+3)(x-2) divided by (x+4)(x+1) over (x+4) after factoring twice

canceling like factors
1 over (x+3) divided by (x+1) over 1
invert denominator and multiply

answer 1 over (x+3)(x+1)

Answer:

∠ QRS = 43°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles and equate to 180

4n - 9 + 5n - 18 + 90 = 180, that is

9n + 63 = 180 ( subtract 63 from both sides )

9n = 117 ( divide both sides by 9 )

n = 13

Thus

∠ QRS = 4n - 9 = 4(13) - 9 = 52 - 9 = 43°

∠ RSQ = 4n - 18 = 4(13) - 18 = 65 - 18 = 47°

The amount of carbon-14 in an object is given by y = ae– 0.00012t where a is the initial amount of carbon and t is the age in ye
Reptile [31]

Answer:

The approximate age of the bone is approximately 11552 years.

Step-by-step explanation:

The current proportion of carbon-14 with respect to its original amount is defined by following formula:

\frac{y}{a} = e^{-0.00012\cdot t} (1)

Where:

y - Current amount of carbon-14, no unit.

a - Initial amount of carbon-14, no unit.

t - Time, in years.

If we know that \frac{y}{a} = 0.25, then the approximate age of the bone is:

t = -8333.333\cdot \ln \frac{y}{a}

t\approx 11552.453\,yr

The approximate age of the bone is approximately 11552 years.

B) Work out (6 * 10^2) /(3 x 10^-5)<br> Give your answer in standard form.
enot [183]

Answer:

come in this question to chat -

brainly.com/question/14180988

Step-by-step explanation:

= 10^2 x 2/ 10^-5

= 10^2/10^-5

= 10^2-(-5)

= 2 x 10^2-(-5)

=10^7 x 2

=10000000 x 2

=20000000

a parallelogram has one angle that measures 55 degrees. what are the measures of the other angles in the parrelogram.
Ugo [173]

a parallelogram has four sides so all its angles add up to make 360

the angle across from the 55 would also be a 55 equaling a 110 degrees angle leaving you with 250 so your other two angles both equal 125
