equation that shows 3 less than the product of 4 and m
The statement is a mathematical statement, and the equation that shows the statement is y = 4m - 3
How to determine the equation?The product of 4 and m is represented as:
4 * m
Evaluate
4 * m = 4m
3 less than this product is represented as:
4 * m - 3 = 4m - 3
Let the result of the equation be represented with y.
So, we have:
y = 4m - 3
Hence, the equation that shows the statement is y = 4m - 3

Step-by-step explanation:
5х + 15 + 3xy +9y factor it
Answer:
(5+3y) (x+3)
first of all you bracket by (5x+15)(3xy+9y). and you start fact as follows by 5(x+3y) 3y(x+3)after here you take (5+3y) (x+3)
Answer:
(x+3)+(5+3y)
Step-by-step explanation: In the equation, when you have four terms you group like terms. So 5x+15 by itself and work it out which you will get 5(x+3) and do the same for 3xy+9y answer is 3y(x+3).
Then you will say 5(x+3)+3y(x+3) and then you'll
5(x+3)/(x+3)=5 because you will cancel the (x+3) so the answer would be 5
You will do the same for 3y(x+3)/(x+3)
you will get 3y
Finally, you will take the first equation which is (x+3), and then you'll use the last equation which is (5+3y)
So that's how you will get (x+3)+(5+3y)
A park is 4 times as long as it is wide. if the distance around the park is 12.5 kilometers, what is the area of the park? 2 answers
Answer:
6.25 km^2.
Step-by-step explanation:
Let the park be x km wide. Then it's length is 4x km.
Perimeter = 2(Length + width)
12.5 = 2(4x + x)
2*5x = 12.5
x = 12.5 /10 =1.25 km.
So the park is 1.25 km wide and 4*1.25 = 5 km long.
The area of the park = 1.25 * 5
= 6.25 km^2.
The dimension of the park is 1.25 km by 5 km. Then the area of the park is 6.25 square km.
What is the area of the rectangle?Let W be the rectangle's width and L its length.
The area of the rectangle is the multiplication of the two different sides of the rectangle. Then the rectangle's area will be
Area of the rectangle = L×W square units
A recreation area is multiple times for however long it is wide. assuming the distance around the recreation area is 12.5 kilometers.
Then the equation is given as,
L = 4W
Then the perimeter of the garden is given as,
12.5 = 2(L + W)
12.5 = 2(4W + W)
6.25 = 5W
W = 1.25 km
Then the length is given as,
L = 4 x 1.25
L = 5 km
Then the area of the garden is given as,
A = 5 x 1.25
A = 6.25 square km
The dimension of the park is 1.25 km by 5 km. Then the area of the park is 6.25 square km.

Step-by-step explanation:
Working from left to right in the square parentheses:-
[6m² x 6n² ÷ 9mn ÷ 2m]²
= [(36m^2n^2 / 9mn) / 2m]^2

Answer:
Slavery caused the Civil War because colored people were being treated unfairly by the South and the North didn't like that. States rights is when a state abides by its own rules. Missouri was allowed to enter the Union as a slave state. California had to decide if they were going to be a slave state or a free state.
Step-by-step explanation:
Slavery was the root of the Civil War in the United States. Following the election of Republican and abolitionist Abraham Lincoln in 1861, southern governments grew fearful of his political beliefs. His victory sparked heated debate in the slave-dependent southern states. Because of the incoming president's future activities, states were planning to secede. These republics were heavily reliant on agriculture, therefore ending slavery would be disastrous. After Lincoln rejected their judgment, the Union and Confederacy declared war on one other. The Confederacy battled and killed to keep slavery alive, but the union won four years later. Abraham Lincoln fought for black people's freedom and human rights while simultaneously fighting to keep the Unified States united. This battle not only ended slavery, but it also brought the states together and preserved a strong country developing together.In the 1860 presidential election, Abraham Lincoln campaigned for president and won, becoming the first republican candidate to do so. His election, on the other hand, brought terrible news to the southern states, which were heavily reliant on agricultural and used slavery to increase revenues. "By and large," according to the book America Past and Present, "By and large, by and large, by and large, by and The civil war began in April 1861, when Southern states attempted to secede from the nation after Abraham Lincoln's election, and concluded in 1865, when the northerners (the Union) triumphed. However, the most crucial reason for the outbreak of the war was that Republican Abraham Lincoln won the election of 1860, and his views on slavery were diametrically opposed to those of the southerners. His election sparked such outrage in the southern states that the possibility of going to war to avoid being linked with his political ideals was floated.

What is trigonometry?
The branch of mathematics sets up a relationship between the sides and the angles of the right-angle triangle are termed trigonometry.
It is given in the question that:-
The base is = 54 cm
Angle just opposite the base is =37

So by applying the cosine formula for the right-angled triangle:-
Cos Ф=(B)/(H)
Cos 53=(54)(x)
x=(54)(Cos53)
x=889.72 cm
Hence the length of the hypotenuse x will be equal to x=89.72 cm.

George receives $237.
find the total amount of money that was shared
The concept of Ratios and shares.
let there be a common multiple 'x' for this ration, hence
5x + 7x + 3x = total money
here, 3x = $ 237
hence, x = $237/3 ==> $79
x = $ 79
hence now the total money that was shared =>
==> 5(79) + 7(79) + 3(79)
==> 395 + 553 + 237
