The sum of three consecutive even integers is 36. Let x represent the first integer, x + 2 represent the second integer, and x +

4 represent the third integer.
Which equation can be used to find the first integer?

a. 2x + 6 = 36

b. 3x + 6 = 36

c. 3x + 36 = 2x + 6

d. 3x = 2x + 6

B.
It will give you a value of 10 for x, which is the first integer you should need.
x+2 : 10+2=12
x+4 : 10+4=14
10+12+14=36

The sum of the measures of the angles of a triangle is 180 degrees. angels A,B,C has ratios of 3:5:7. What are their measures ?
Igoryamba

Answer:

<em>36:60:84</em>

<em>A     : B    : C</em>

<em>36° : 60° : 84°</em>

<em>A= 36°</em>

<em>B= 60°</em>

<em>C=84°</em>

Step-by-step explanation:

<em>3:5:7 =15</em>

<em>180÷15=12</em>

<em>3×12=36</em>

<em>36:x:y =180</em>

<em>5×12=60</em>

<em>36:60:y =180</em>

<em>7×12=84</em>

<em>36:60:84 =180</em>

PLEASE HURRY Write the equation as a single logarithm 3log(x-2)+2log(x+2)
zubka84 [21]

Answer:

3\,log (x-2)+2\,log(x+2) can be written as the single logarithm:

log((x-2)^3\,(x+2)^2)

Step-by-step explanation:

Start by using in both terms of the expression the property of logarithm of a power that states:

log(a^b)=b\,*\,log(a)

so we recognize that the factor that multiplies each logarithmic expression, can be understood as the power of the argument of the function logarithm:

3\,log(x-2)=log((x-2)^3)\\and\\2\,log(x+2)=log((x+2)^2)

Then we use the property of logarithm of a product which states that:

log(a*b)=log(a)+log(b)

So now we recognize the expression:

log((x-2)^3)\,+\,log((x+2)^2)

as the logarithm of the product:

log((x-2)^3\,(x+2)^2)

which is finally a single logarithm as requested.

Write a rational inequality with the solution: (-2,-1)U(1, oo)
serg [7]

Answer:

\displaystyle \frac{x^2+3x+2}{1-x}

Step-by-step explanation:

<u>Rational Inequality</u>

We are given the solution of rational inequality:

(-2,-1) U (1,∞)

The first set suggests a limited zone than can be obtained by a quadratic equation of the form:

(x-a)(x-b)

Where a and b are the roots of the equation, which coincide with the endpoints of the interval. Thus, to get the interval, we can use:

(x+2)(x+1)

Operating:

x^2+3x+2

The second set is an open infinite interval, that can be modeled as a third binomial that changes signs in x=1 and is in the denominator, so x=1 is not included.

Thus, one possible inequality is:

\mathbf{\displaystyle \frac{x^2+3x+2}{1-x}
