Answer:
X = (2a + 5)^2 = 4a^2 + 20a + 25
Y = (a-3)^2 = a^2 - 6a + 9
4a^2 + 20a + 25 + a^2 - 6a + 9
X + Y = 5a^2 + 14a + 34

help me with my homework
Answer:
a because I dont know why but some one told me it was this
Answer: A. There are three terms
Concept:
In an algebraic expression, there are several specific terms:
Constant: the individual number that has no variable with it, or in east word, it is isolated.Variable: any unknown value, which is usually presented by alphabets.Coefficients: the numbers that are bounded with a variable, usually in front of a variable.Terms: the number of individuals present in the expression, which is constants and [variable + coefficients].Like terms: terms that have the same variables and powers.If you are still confused, you may refer to the attachment below for a graphical explanation.
Solve:
a. There are three terms. [tex]\boxed{FALSE}[/tex]
- 14b
- -7
- 8b
- b
There are in total four individuals, which means there are four terms.
b. There is one constant term. [tex]\boxed{TRUE}[/tex]
- 14b is a [variable + coefficient]
- -7 is a [constant]
- 8b is a [variable + coefficient]
- b is a [variable]
Therefore, there is one constant term.
c. The coefficients are 14, 8, and 1 [tex]\boxed{TRUE}[/tex]
- 14b →→→ 14 is the [coefficient]
- -7 →→→ is a [constant]
- 8b →→→ 8 is the [coefficient]
- b →→→ 1 is the [coefficient]
Therefore, 14, 8, and 1 are coefficients.
d. Three of the terms are like terms [tex]\boxed{TRUE}[/tex]
- 14b →→→ b is the [variable]
- -7 →→→ is a [constant]
- 8b →→→ b is the [variable]
- b →→→ b is the [variable]
Since 14b, 8b, and b share the common variable, there are three like terms.
Hope this helps!! :)

What is the volume, in ml, of 100. grams of mercury? Mercury has a density of 13.54 g/mL
(which means 1mL=13.54 g).
13.54 g/mL = (100 g)/v
==> v = (100 g)/(13.54 g/mL) = 7.39 mL
The volume of 100 grams of mercury is 7.38 mL when the density of mercury is 13.54 g/mL.
To calculate the volume of 100 grams of mercury, we can use the density formula:
Density = Mass / Volume
We are given the density of mercury as 13.54 g/mL, and we want to find the volume in mL.
Volume = Mass / Density
Substituting the given values:
Volume = 100 g / 13.54 g/mL
Simplifying the division:
Volume= 7.38 mL
Therefore, the volume of 100 grams of mercury is 7.38 mL.

The sum of three numbers is 62. The second number is triple the first, and the third is six more than the
second. Find the numbers.
Answer:
The numbers are 8, 24 and 30
Step-by-step explanation:
Let x be the first number.
If the second number is triple the first, then the second number is 3x
If the third number is the second number plus six, then the third number is 3x + 6
So therefore the equation is:
[tex]x + 3x + (3x + 6) = 62[/tex]
Solving for x,
[tex]x + 3x + 3x + 6 = 62\\7x = -6 + 62\\7x = 56\\x = 8[/tex]
But why is the second number 24?
[tex]3x = 24\\3(8) = 24\\24 = 24[/tex]
And why is the third number 30?
[tex]3x + 6 = 30\\24 + 6 = 30\\30 = 30[/tex]
State one form of the Law of Cosines and provide a trick for writing the other two forms and explain when Law of Cosines should be used to solve a triangle.
Solving for Angles
[tex]\displaystyle \frac{a^2 + b^2 - c^2}{2ab} = cos∠C \\ \frac{a^2 - b^2 + c^2}{2ac} = cos∠B \\ \frac{-a^2 + b^2 + c^2}{2bc} = cos∠A[/tex]
* Do not forget to use the inverse function towards the end, or elce you will throw your answer off!
Solving for Edges
[tex]\displaystyle b^2 + a^2 - 2ba\:cos∠C = c^2 \\ c^2 + a^2 - 2ca\:cos∠B = b^2 \\ c^2 + b^2 - 2cb\:cos∠A = a^2[/tex]
You would use this law under two conditions:
One angle and two edges defined, while trying to solve for the third edgeALL three edges defined* Just make sure to use the inverse function towards the end, or elce you will throw your answer off!
_____________________________________________
Now, JUST IN CASE, you would use the Law of Sines under three conditions:
Two angles and one edge defined, while trying to solve for the second edgeOne angle and two edges defined, while trying to solve for the second angleALL three angles defined [of which does not occur very often, but it all refers back to the first bullet]* I HIGHLY suggest you keep note of all of this significant information.

You start at (0, 2). You move right 2 units and down 4 units. Where do you end?
Answer:
(2, -2)Step-by-step explanation:
Translation left or right adds to x-coordinate, translation up or down adds to y-coordinate.
Given coordinate (0, 2) and translation is 2 units right and 4 units down:
x = 0 + 2 = 2y = 2 - 4 = -2The end points is (2, -2)
We have to move x co ordinates 2 more and y coordinate 4less
Do it

(-4+ 8x) +3>
What is the solution to the inequality
-4?
Step-by-step explanation:
if I understand the typed information here, we have
(-4 + 8x) + 3 > -4
so, I am looking at that :
-4 + 8x + 3 > -4
let's first add 4 on both sides
8x + 3 > 0
then subtract -3 on both sides
8x > -3
and finally divide both sides by 8
x > -3/8
since we never multiplied or divided by a negative number, the inequality sign stays the same.
so, this inequality is true for all x > -3/8

$9
Yuri pays $124.60 to park his car.
How many days does he park his car for?
Show your working.
Answer:
He paid $9 twelve times
12× 2= 24 days
Step-by-step explanation:
1st day = $16.60
3rd day=$ 9 (i.e for every 2days afterwards)
5th day=$ 9
Yuri pays : 124.60
124.60-16.60
= $108.00
After paying the first day he paid 108.00
108.00÷ 9 = 12
He paid $9 twelve times
12× 2= 24 days

Martinez town is building a volleyball court based on a scale drawing that is 40cm by 80cm and uses the scale 1 cm :22.5cm
The proportional relationship between drawing court lengths x in centimeters and court lengths in y centimeters is y = 22.5x
Your question is not complete, it seems to be missing the following information;
"write an equation for the proportional relationship between drawing court lengths x in centimeters and court lengths in y centimeters"
The drawing court length is given as;
x = 40 cm or 80 cm
drawing scale = 1 cm : 22.5 cm
The corresponding length of the court is calculated as;
when x = 40 cm;
[tex]y = \frac{22.5}{1} \times 40 cm = 900 \ cm[/tex]
when x = 80 cm;
[tex]y = \frac{22.5}{1} \times 80 \ cm = 1,800 \ cm[/tex]
The proportional relationship between drawing court lengths x in centimeters and court lengths in y centimeters is calculated as;
[tex]\frac{y}{x} = \frac{900}{40} = \frac{1800}{80} \\\\\frac{y}{x} = 22.5\\\\y = 22.5 x[/tex]
Thus, the proportional relationship between the lengths is y = 22.5x
