Express as a trinomial.
(2 – 4)(2x + 3)

Answers

Answer:

-2(2x+3)

Step-by-step explanation:

Answer:

-2 (2x + 3)

Step-by-step explanation:

We need to use FOIL

Multiply the FIRST terms of each set together

Then the OUTSIDE terms

Then the INSIDE terms

and then the LAST terms

Thus:

[tex]2*2x = 4x[/tex]

[tex]2*3 = 6[/tex]

[tex]-4*3 = -12[/tex]

[tex]-4*2x = -8x[/tex]

So finally we end up with 4x + 6 - 12 - 8x

Simplifying this gives us -4x - 6

We can then factor out -2 from each factor, giving: -2(2x+3)

Hope this helps!

In the equation a and b represent the price per night for a room in hotel a and hotel b respectively w week s

Answers

Answer:

A = $80

Step-by-step explanation:

A = 240 - 20w

B = 320 - 30w

Equate both equations

240 - 20w = 320 - 30w

Collect like terms

240 - 320 = -30w + 20w

-80 = -10w

Divide both sides by -10

w = -80/-10

w = 8

Substitute w into equation A

A = 240 - 20w

= 240 - 20(8)

= 240 - 160

= 80

A = $80

A circle has a radius of 4 feet. What is the radius of a bigger circle if the scale factor of the smaller to bigger is 4:9

Answers

Answer:

9 feets

Step-by-step explanation:

From the question, we have our scale factor as:

4:9 = 4/9

Smaller circle /Bigger circle = 4/9

A circle has a radius of 4 feet. What is the radius of a bigger circle?

Let the radius of the bigger circle = x

This is calculated as:

4/9 = 4/x

Cross Multiply

4x = 9 × 4

x = 36/4

x = 9 feet

Therefore, the radius of the bigger circle is 9 feet

What’s 25 dived by 9 in long (step by step)

Answers

Answer:

Step 1:

Start by setting it up with the divisor 9 on the left side and the dividend 25 on the right side like this:

9 ⟌ 2 5

Step 2:

The divisor (9) goes into the first digit of the dividend (2), 0 time(s). Therefore, put 0 on top:

9 ⟌ 2 5

Step 3:

Multiply the divisor by the result in the previous step (9 x 0 = 0) and write that answer below the dividend.

9 ⟌ 2 5

Step 4:

Subtract the result in the previous step from the first digit of the dividend (2 - 0 = 2) and write the answer below.

9 ⟌ 2 5

- 0

Step 5:

Move down the 2nd digit of the dividend (5) like this:

9 ⟌ 2 5

- 0

Step 6:

The divisor (9) goes into the bottom number (25), 2 time(s). Therefore, put 2 on top:

0 2

9 ⟌ 2 5

- 0

2 5

Step 7:

Multiply the divisor by the result in the previous step (9 x 2 = 18) and write that answer at the bottom:

9 ⟌ 2 5
