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

What’s 25 dived by 9 in long (step by step)
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:
0
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.
0
9 ⟌ 2 5
0
Step 4:
Subtract the result in the previous step from the first digit of the dividend (2 - 0 = 2) and write the answer below.
0
9 ⟌ 2 5
- 0
2
Step 5:
Move down the 2nd digit of the dividend (5) like this:
0
9 ⟌ 2 5
- 0
2 5
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:
0 2
9 ⟌ 2 5
- 0
2 5
1 8
Step 8:
Subtract the result in the previous step from the number written above it. (25 - 18 = 7) and write the answer at the bottom.
0 2
9 ⟌ 2 5
- 0
2 5
- 1 8

Three cups of sugar and six cups of flour are required to bake the cake, if for cake calls for a ratio of 1 cup of sugar for every 2 cups of flour.
What is division?It is the basic arithmetic operation, in which you are separating the number into some parts.
Given data:
A recipe for cake calls for a ratio of 1 cup of sugar for every 2 cups of flour.
Calculate the ratio for 1 cake
1 cup of sugar / 2 cups of flour
Calculate the sugar and flour for 3 cake
1 cup of sugar / 2 cups of flour × 3
3 cups of sugar / 6 cups of flour
Therefore, 3 cups of sugar and 6 cups of flour are required to bake the cake if for cake calls for a ratio of 1 cup of sugar for every 2 cups of flour.

Mr. Rojas spent d dollars to go on vacation. He bought a plane ticket for $250 and stayed in a hotel for 5 nights. If the cost of the hotel room was the same each night, what expression can be used to find how much Mr. Rojas paid each night for the hotel?
Answer:
x = d/5 - $50
Step-by-step explanation:
Basiclly what this sentence is saying that the price d is equal to $250 + 5 prices of staying in a hotel for a night.
If we let "x" be the price per night then we can get the following..
d = $250 + 5x
5x = d - $250
[tex]x = \frac{d - 250}{5}[/tex]
x = d/5 - $50

Which graph represents an exponential function?
Answer:
b
Step-by-step explanation:
The second graph, which represents Table B, represents an exponential function.
What is an exponential function?Mathematical functions with exponents include exponential functions. f(x) = bˣ, where b > 0 and b 1, is a fundamental exponential function.
Let table A represents the first graph.
x: 0, -1, 1, 2, -2, 3, -3.
y: 0, -1, -1, -4, -4, -6, -6.
And table B represents the second graph.
x:-4, -3,-2.75, -2.
y: 2, 4, 6, 10
To determine which graph represents an exponential function, we need to recall the properties of exponential functions. An exponential function is a function of the form y = a^x, where a is a constant greater than 0 and not equal to 1.
Looking at table A, we can see that the y-values do not appear to follow an exponential pattern. For example, the y-values for x = 1 and x = -1 are both -1, but the y-value for x = 2 is -4. This is not consistent with the pattern of an exponential function.
Looking at table B, we can see that the y-values do appear to follow an exponential pattern. The y-values increase rapidly as x increases, which is consistent with the pattern of an exponential function. To confirm this, we can calculate the ratio of consecutive y-values:
For x = -4 and x = -3, y increases by a factor of 4/2 = 2.
For x = -3 and x = -2.75, y increases by a factor of 6/4 = 1.5.
For x = -2.75 and x = -2, y increases by a factor of 10/6 = 1.67.
These ratios are not exactly the same, but they are approximately equal to each other. This is consistent with the pattern of an exponential function, where the ratio of consecutive y-values is constant.
Therefore, the second graph, which represents Table B, represents an exponential function.

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

Answer:
X = 9.2
Step-by-step explanation:
You have to use the pythagorean theorm, which is a squared + b squared = c squared. Looking at the triangle, the vertical line is 6, and the horizontal is 7.
6squared + 7squared = c squared
85 = csquared
Take the square root of both sides to get rid of the squared on the c.
sqroot of 85 = 9.2
