I need helppppp it’s geometry

I think it is done like this but I am not sure.

Simplifying

9 + -4(2x + -1) = 45

Reorder the terms:

9 + -4(-1 + 2x) = 45

9 + (-1 * -4 + 2x * -4) = 45

9 + (4 + -8x) = 45

Combine like terms: 9 + 4 = 13

13 + -8x = 45

Solving

13 + -8x = 45

Solving for variable 'x'.

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

Add '-13' to each side of the equation.

13 + -13 + -8x = 45 + -13

Combine like terms: 13 + -13 = 0

0 + -8x = 45 + -13

-8x = 45 + -13

Combine like terms: 45 + -13 = 32

-8x = 32

Divide each side by '-8'.

x = -4

Simplifying

x = -4

The solution to the equation 9 - 4(2x - 1) = 45 is x = -4.

We have,

Distribute the -4 to the terms inside the parentheses:

9 - 4(2x - 1) = 45

9 - 8x + 4 = 45

Combine like terms:

13 - 8x = 45

Move the constant term to the other side of the equation by subtracting 13 from both sides:

13 - 8x - 13 = 45 - 13

-8x = 32

Divide both sides of the equation by -8 to isolate the variable:

(-8x) / (-8) = 32 / (-8)

x = -4

Therefore,

The solution to the equation 9 - 4(2x - 1) = 45 is x = -4.

Answer:

4372 people would have been sick over time.

Step-by-step explanation:

Since the vaccine would be found in a week, then the over time is a week (7 days). Each day, a sick person infects two additional people.

Number of people infected by Velma can be predicted as follows:

Day 1 - 2, Day 2 - 6, Day 3 - 18, Day 4 - 54, Day 5 - 162, Day 6 - 486, Day 7 - 1458

Number of people infected by Velma = 1458 + 486 + 162 + 54 + 18 + 6 + 2

                                                       = 2186

Also, number of people infected by Stanley can be predicted as follows:

Day 1 - 2, Day 2 - 6, Day 3 - 18, Day 4 - 54, Day 5 - 162, Day 6 - 486, Day 7 - 1458

Number of people infected by Stanley = 1458 + 486 + 162 + 54 + 18 + 6 + 2

                                                       = 2186

Total number of people than can be infected over time = 2186 + 2186

                                                      = 4372

Therefore, the predictable number of infected people over time would be 4372. All citizens of Parsnipville would have been infected before the vaccine is available.

ASSUMING that only 4 new people get sick a day then we would have the equation 4x+2

Answer:

push the x on the top left corner of the tab

Step-by-step explanation:

Answer:

first day = 5.05mm = 0.505cm

second day = 9.55mm = 0.955cm

Step-by-step explanation:

Let x represent first day

Let y represent second day

x + y = 14.6

x = y - 4.5

(y - 4.5) + y = 14.6

2y - 4.5 = 14.6

2y = 14.6 + 4.5

2y = 19.1

Divide both sides by coefficient of y which is 2

y = 9.55

Substituting value of y in the equation x + y = 14.6

x + 9.55 = 14.6

x = 14.6 - 9.55

x = 5.05

To convert the values in mm to cm you divide them by 10 since 1cm=10mm

Answer:

See below.

Step-by-step explanation:

Start with triangle ABC with side BC lying on line n.

Draw a line through point A parallel to line n, and call it line m.

Angles 1 and 3 are alternate interior angle of parallel lines and are congruent.

Angle 2 and 4 are alternate interior angles of parallel lines and are congruent.

The sum of the measures of angles angles 1, BAC, and 2 is 180 since they lie on a line.

m<1 + m<BAC + m<2 = 180

Now we substitute in the angles we know are congruent by alternate interior angles (written above).

m<3 + m<BAC + m<4 = 180

Steps to solve:

3 - 4y = 19

~Subtract 3 to both sides

-4y = 16

~Divide -4 to both sides

y = -4

Best of Luck!

Total cost = ($8.50b) + ($3.99d)

Step-by-step explanation:

In a bakery, the cost of a dozen bagels = $8.50

and the cost of a dozen donuts = $3.99

1 Dozen = 12 pieces

Let 'b' represents the number of bagels (in dozen) and d represents dozen donuts.

The expression that represents total cost of b dozen bagels and d dozen donuts would be :

Total cost = ($8.50b) + ($3.99d)

Answer: 2(2x + 3)(x - 6)

Step-by-step explanation: For any factoring problem you do, your first

task will be to determine if a GCF exists for the original polynomial.

If a GCF does exist, it must be factored out as the first step to the problem.

In the problem you see here, the 3 terms in

the original polynomial have a GCF of 2.

So a 2 must be factored out as your first step.

This leaves you with 2(2x² - 9x - 18).

This does not make your life a whole lot easier however

because you still have a coefficient on the x squared term.

Factoring from here, you get 2(2x + 3)(x - 6).

Answer:

2(x - 6)(2x + 3)

Step-by-step explanation:

There are a few steps to factoring depending on the polynomial.

Step 1. Factor our a common factor if possible.

Every term is divisible by 2, so factor out a 2.

4x^2 - 18x - 36 =

= 2(2x^2 - 9x - 18)

Step 2. We need to factor the quadratic trinomial.

Now we have a quadratic trinomial, in which the x^2 term is not plain x^2, but it has a coefficient of 2.

Our polynomial is of the form ax^2 + bx + c, with "a" not equal to 1.

We have 2x^2 - 9x - 18, so we have a = 2, b = -9, c = -18.

We can try guessing, but instead, I will use the "ac" method.

Step A. Multiply coefficients ac:

ac = 2(-18) = -36

Step B. Now we need two numbers that add to b and multiply to ac.

We need two numbers that add to -9 and multiply to -36.

The numbers are -12 and 3 since (-12)(3) = -36, and -12 + 3 = -9.

We now break up the middle term, -9x, using these two numbers.

= 2(2x^2 - 12x + 3x - 18)

Now we factor by grouping. Factor a common factor out of the first two terms, and factor a common factor out of the last two terms.

= 2[2x(x - 6) + 3(x - 6)]

x - 6 is a common factor inside the brackets, so we factor it out inside the brackets.

= 2[(x - 6)(2x + 3)]

= 2(x - 6)(2x + 3)
