Answer:
2x^2-8x
Step-by-step explanation:
Apply the distributive property.
2x⋅x+2x⋅−4
2x^2+2x⋅−4
=2x^2-8x
The simplification of the expression would be; 2x²-8x
What is distributive property?The distributive property states that an equation of the form A(B + C) can be solved by a multiplication over addition operation that isA(B + C) = AB + AC
This property is known by distributive law and applies to subtraction also.
Usually, simplification involves proceeding with the pending operations in the expression and Simplification usually involves making the expression simple and easy to use later.
Apply the distributive property.
2x⋅x+2x⋅−4
2x²+2x⋅−4
Then the simplify the expression as;
=2x²-8x

Answer:
The attached graph shows my answer.
Step-by-step explanation:
The graph has to start at the top because the number of carrots has to decrease and the graph slants down to the right because the time has to increase. Then the situation says that he eats one carrot at a time until half are eaten. The graph shows the line going down until approximately half. Then he doesn't eat any more, so the line is horizontal until the end of the graph to show no change.
An arrow is shot at 30.0° above the horizontal. Its velocity is 49 m/s, and it hits the target.
What is the maximum height the arrow will attain?
Answer:
30.625 m
Step-by-step explanation:
Maximum Height :
(u²sin²θ) / 2g
u = 49 m/s
θ = 30°
g = 9.8m/s
(49² * 0.5²) / 2 * 9.8
600.25 / 19.6
= 30.625 m
If a point A has coordinates (1,2) and point B has coordinates (9,8), what is the distance between points A and B?
Distance between the 2 points is 10.
Step-by-step explanation:
Answer:
10
Step-by-step explanation:
Use the distance formula to determine the distance between the two points.
[tex]\sqrt{(x2-x1)^2+(y2-y1)^2} \\[/tex]
Substitute the actual values of the points into the distance formula.
[tex]\sqrt{(9-1)^2+(8-2)^2}[/tex]
Simplify,
[tex]\sqrt{100}[/tex]
Rewrite
[tex]\sqrt{10^2}[/tex]
Pull terms out from under the radical, assuming positive real numbers.

A serving of four home baked chocolate chip cookies weigh 50 grams and contains 12 grams of fat. What is the ratio in lowest terms of fat grams to total grams?
Answer:
Good luck
Step-by-step explanation:
(50) half it
(25) (25)
(12) (12)
(12.5) (12.5) (12.5) (12.5)
(12) (12) (12) (12)
0.5 + 0.5 + 0.5 + 0.5 = 2 (0.5= 1/2 or 0.5 or 0.50)
more examples: (2/4) (3/6) (4/8) (5/10)
So you are gonna have four holes and two twelves
(12/12) (12/12) (12/12) (12/12) (2/12)
The ratio of fat to total weight in the lowest form is 25 : 6.
What are ratio and proportion?A ratio is a comparison between two similar quantities in simplest form.
Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.
In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.
Given, Four Home-baked chocolate chip cookies weigh 50 grams and contain 12 grams of fat.
We know a/b can be written in ratio form as a : b.
∴ Fat/Total weight = 50/12.
Fat/Total weight = 25/6.
Fat : Total weight = 25 : 6.

a train moves 12 miles in 18 minutes. of the train maintains that speed for 75 minutes, how many miles will it travel.
Answer:
112.5
Step-by-step explanation:
18 divided by 12 is 1.5
then multiply 1.5 and 75
1.5 x 75 = 112.5
very sorry if this is wrong
18 min=12 miles
1 min=12/18
75 min=12/18×75
if you simplify well you get,
75 min=46 miles

20 - 2x, if x = 10
First, plug in 10 for each value of x.
20 - 2(10) = ?
Next, multiply 2 and 10 due to PEMDAS. (parentheses/exponents, multiplication/division, addition/subtraction)
20 - 20 = ?
Now, subtract.
= 0
