(2x+4) +(3x-1) +(x+1)=34
6x+4=34
x=5
AB=14, BC=14, AC=6

AB=BC
2x+4=3x-1
2x+5=3x
5=x
AC=x+1
5+1
6
AB=2x+4
2(5)+4
10+4
14
BC=3x-1
3(5)-1
15-1
14
AC+AB+BC=34
14+14+6=34
14+20=34
34=34

Can somebody help me with these problems please

Answer:

11. A. $\frac{12}{13}$

12. D. $\frac{35}{12}$

Step-by-step explanation:

11: Sin is just the side opposite of the angle divided by the hypotenuse of the triangle

Opposite of A = 36

Hypotenuse of the triangle = 39

36/39 = $\frac{12}{13}$

12. Tan is the side opposite of the angle divided by the side adjacent to the angle

Opposite of C = 35

Adjacent to C = 12

35/12 = $\frac{35}{12}$

Hope this helps!

Let f (x) = 1/x<br> and g(x) = x² – 3x. What<br> two numbers are not in the domain of fºg?

iren [92.7K]

For this case we have the following equations:

$f (x) = \frac {1} {x}\\g (x) = x ^ 2-3x$

We must find $(f_ {o} g) (x):$

By definition of composition of functions we have to:

$(f_ {o} g) (x) = f (g (x))$

So:

$(f_ {o} g) (x) = \frac {1} {x ^ 2-3x}$

We must find the domain of f (g (x)). The domain will be given by the values for which the function is defined, that is, when the denominator is nonzero.

$x ^ 2-3x = 0\\x (x-3) = 0$

So, the roots are:

$x_ {1} = 0\\x_ {2} = 3$

The domain is given by all real numbers except 0 and 3.

Answer:

x other than 0 and 3

Two less than 3/2 of a number (x) is more than 5 1/2

garik1379 [7]

Answer:

3/2x-2>5 1/2

Step-by-step explanation:

Two less than a number means we are subtracting 2, so we can write it into the equation as -2.

Since we dont know the value of x, we can just write 3/2 of x by multiplying 3/2 by x. So 3/2x. Also, since we are subtracting two from 3/2x, -2 comes after 3/2x.

Now, since it says that it is more than 5 1/2, we could use the greater than sign (>), to express that. So >5 1/2

Our final expression is 3/2x-2>5 1/2.

Hope this helps!

three friends earned more then $200 washing cars. they paid their parents $28 for supplies and divides the rest of money equally

Allushta [10]

X is each friend
3x + 28 > 200
3x > 172
