7. Veronica is choosing between two health clubs.

vesna_86 [32]

Answer:

The total cost for each health club will be the same after 4 months.

Step-by-step explanation:

Let A = membership fee for studio A

B = membership fee for studio B

x= membership month

$A = 22 + 24.5x$

$B = 47.00 + 18.25x$

We want to when the total cost at each health studio is the same.

In other words, when A = B.

Therefore, the expression becomes

$A = B$

$22\:+\:24.5x=47.00\:+\:18.25x$

Step 1: Simplify both sides of the equation.

$24.5x+22=18.25x+47$

Step 2: Subtract 18.25x from both sides.

$24.5x+22-18.25x=18.25x+47-18.25x$

$6.25x+22=47$

Step 3: Subtract 22 from both sides.

$6.25x+22-22=47-22$

$6.25x=25$

Step 4: Divide both sides by 6.25

$\frac{6.25x}{6.25}=\frac{25}{6.25}$

$x=4$

Therefore, the total cost for each health club will be the same after 4 months.

What is the simplified form of square root of 144x^36?

trasher [3.6K]

Answer:

The correct option is B.

Step-by-step explanation:

The given expression is

$\sqrt{144x^{36}}$

Use the property of radicals.

$\sqrt{ab}=\sqrt{a}\sqrt{b}$

$\sqrt{144x^{36}}=\sqrt{144}\times \sqrt{x^{36}}$

Use the property of exponent.

$a^{mn}=(a^m)^n$

$\sqrt{144x^{36}}=12\times \sqrt{(x^{18})^2}$

$\sqrt{144x^{36}}=12\times x^{18}$

$\sqrt{144x^{36}}=12x^{18}$

Therefore option B is correct.
