Answer:

x > -3

Step-by-step explanation:

–3x + 6 < 15

Subtract 6 from each side

–3x + 6-6 < 15-6

-3x < 9

Divide each side by -3, remembering to flip the inequality

-3x/-3 > 9/-3

x > -3

Answer:

Step-by-step explanation:

given that x and y are proportional, they can be expressed as y = rx, where r is the proportionality constant. Thus, we can solve for r by doing y/x in any given point.

$\frac{8}{1.6} = \frac{15}{3} = \frac{22}{4.4} = 5$

Please help me answer this equation

krok68 [10]

Answer:

Step-by-step explanation:

What you do is try to find l by using the given information.

We can start by saying that

A=L*W

Now it's easy algebra

Divide both sides by W

L=A/W

Area and length are given .

A=((m^3-3m+2)/2m^2-7m+3)/(m^3+m-2)/(2m^3+3m-2)

Try to work it out if you can't then tell me in the comments we'll figure it out.

Left parenthesis 5 plus 2 square root of 6 right parenthesis squared = a plus b square root of 6 then the value of a and b are

Ganezh [65]

Answer:

The values of $a$ and $b$ are $33$ and $\frac{20\sqrt{3}}{3}$ , respectively.

Step-by-step explanation:

The statement is equivalent to the following mathematic expression:

$\left(5 + 2\sqrt{2})^{2} = a + b\cdot \sqrt{6}$ (1)

By definition of the perfect square trinomial:

$25 + 20\cdot \sqrt{2} + 8 = a + b\cdot \sqrt{6}$

$33 + 20\sqrt{2} = a + b\cdot \sqrt{6}$

And by direct comparison we have the following system:

$a = 33$ (2)

$b\cdot \sqrt{6} = 20\sqrt{2}$ (3)

By (3), we solve for $b$ :

$b = \frac{20}{\sqrt{3}}$

$b = \frac{20\sqrt{3}}{3}$

The values of $a$ and $b$ are $33$ and $\frac{20\sqrt{3}}{3}$ , respectively.
