Answer:

14x - 6

Step-by-step explanation:

P = 2(length + width)

P = 2(6x - 2 + x - 1) = 2(7x - 3) = 14x - 6

Find A. Round to the nearest tenth.

Marianna [84]

Answer:

27.8 degrees

Step-by-step explanation:

Wasn't it 'a,' not 'A,' that you wanted?

The ratio a/ 30 is the cosine of the angle 22 degrees, which in turn is 0.927:

a

Then 0.927 = ------- which yields a = 30(0.927) = 27.8 degrees

For what values of x is x2+2x=24 true?

JulijaS [17]

Answer:

$x=-6$ and $x=4$

Step-by-step explanation:

We must solve the quadratic equation to find the values of x that satisfy equality

$x^2+2x=24$

Subtract 24 on both sides of equality

$x^2+2x-24=24-24$

$x^2+2x-24=0$

Now we factor the quadratic equation

Identify two numbers that when you add them you get as a result 2 and when you multiply them you get as a result -24

The numbers sought are: 6 and -4

So the factors are:

$(x+6)(x-4)=0$

Finally note that the solutions are:

$x=-6$ and $x=4$
