So first, you want to open the parenthesis here.

So, to do that, first look at the symbol before the parenthesis.

In this case it's a -.

So when it's a -, reverse the symbol inside the parenthesis. (This is because if you don't you're subtracting 2x and then adding 8, when really you're subtracting both 2x and 8.)

So,

9x - 2x - 8

Or simplified,

7x - 8

Aneesha travels at 50 mph. Morris is traveling at 3 feet per second less than Aneesha. How fast is Morris traveling

vampirchik [111]

Speed of Morris is 47.95 mph

Step-by-step explanation:

Step 1: Convert 3 feet per second to miles per hour.

⇒ 3 ft/s = 3/1.467 mph (∵ 1 mph = 1.467 ft/s)

= 2.05 mph

Step 2: Find the speed of Morris.

Speed of Morris = 50 mph - 2.05 mph = 47.95 mph

You are currently paying rent every year for your restaurant. You still have a contract that will last 2 more years. Starting to

Andreas93 [3]

The amount to be paid in rent after 2 years if the rent as of now is $3,000 will be; $3,213.675

The question allows that we choose the amount being paid as rent as of now.

Let the rent paid as of now be; $3,000

In essence; after the first year; the amount increases by 3.5% to become;

1.035 × $3,000

= $3,105.

After the second year; we have;

1.035 × $3,105

= $3,213.675

Ultimately; the amount to be paid after 2 years will be; $3,213.675.

When given the opportunity to change rent contracts;

A situation that will be beneficial would be a 3.5% reduction in rent per year
A situation that will not be beneficial would be a 7% increase in rent per year.

Factor completely. 36c^2−8cd+49d^2

Molodets [167]

$\huge\bold\green{Answer:-}$

Simplifying

36c2 + -84cd + 49d2 = 0

Reorder the terms:

-84cd + 36c2 + 49d2 = 0

Solving

-84cd + 36c2 + 49d2 = 0

Solving for variable 'c'.

Factor a trinomial.

(6c + -7d)(6c + -7d) = 0

Subproblem 1

Set the factor '(6c + -7d)' equal to zero and attempt to solve:

Simplifying

6c + -7d = 0

Solving

6c + -7d = 0

Move all terms containing c to the left, all other terms to the right.

Add '7d' to each side of the equation.

6c + -7d + 7d = 0 + 7d

Combine like terms: -7d + 7d = 0

6c + 0 = 0 + 7d

6c = 0 + 7d

Remove the zero:

6c = 7d

Divide each side by '6'.

c = 1.166666667d

Simplifying

c = 1.166666667d

Subproblem 2

Set the factor '(6c + -7d)' equal to zero and attempt to solve:

Simplifying

6c + -7d = 0

Solving

6c + -7d = 0

Move all terms containing c to the left, all other terms to the right.

Add '7d' to each side of the equation.

6c + -7d + 7d = 0 + 7d

Combine like terms: -7d + 7d = 0

6c + 0 = 0 + 7d

6c = 0 + 7d

Remove the zero:

6c = 7d

Divide each side by '6'.

c = 1.166666667d

Simplifying

c = 1.166666667d

Solution

c = {1.166666667d, 1.166666667d}
