Step-by-step explanation:
[tex]( - 3 {x}^{2} - 9x) \div (x + 3) [/tex]
This is the original equation so you will open the brackets.
[tex] - 3 {x}^{2} - 9x \div x + 3[/tex]
The x will cross the division sign making it times x.
[tex]3 {x}^{2} - 9x \times x = 3[/tex]
So you will proceed to multiply the 9x by x making it;
[tex]3 {x}^{2} - 9 {x}^{2} = 3 [/tex]
So you will subtract 9x² from 3x² which won't be possible so it will be negative.
[tex] - 6 {x}^{2} = 3 [/tex]
Then you will square root both sides making it;
[tex] - \sqrt{6 {x}^{2} } = \sqrt{3} [/tex]
So the ² will cancel the √ leaving
-6x=√3
-6x=1.73(Divide both sides by -6)
x=0.288
That's the final answer.

Club 1 has a $40 fee + 2 books = $60 in total
Club 2 has a $0 fee + 4 book = $60 in total
I'm pretty sure I'm right
Answer:
There would have to be 2 books purchased from the first club. Then, there would have to be 4 books purchased from the second club.
Step-by-step explanation:
1st club. (cost of club) 40$ + (cost of 2 books) 20$ = 60$.
2nd club. (cost of books) 15$ x (how many books) 4 = 60$

Find the values of x and y if
Answers
Answer:
see explanation
Step-by-step explanation:
Since the triangles are congruent then corresponding sides are congruent, then
CA = NE , that is
4x + 3 = 11 ( subtract 3 from both sides )
4x = 8 ( divide both sides by 4 )
x = 2
----------------------------------------
AR = EW, that is
4y - 12 = 10 ( add 12 to both sides )
4y = 22 ( divide both sides by 4 )
y = 5.5

NW = x + y = 2 + 5.5 = 7.5
CR = NW = 7.5

Jill saw three small boxes and one large box of oranges for a total cost of $29 Bethany saw three small boxes and four large boxes for a total of 71 in the cost of a small box in a large box of oranges
Answers
Answer: Small box = $5
Large box = $14
Step-by-step explanation:
Let the cost of a small box be a
Let the cost of a large box be b
The scenario in the question can be modelled into an equation as:
3a + b = 29 ....... equation i
3a + 4b = 71 ....... equation ii
Subtract equation ii from equation I
-3b = -42
b = 42/3
b = 14
Cost of large box = $14
We put the value of b into equation I
3a + b = $29
3a + $14 = $29
3a = $29 - $14
3a = $15
a = $15/3
a = $5
Cost of small box = $5

Make x the subject of formula x²/a²+y²/b²=1
Answers
Answer:
x = ± [tex]\sqrt{\frac{a^2b^2-a^2y^2}{b^2} }[/tex]
Step-by-step explanation:
Given
[tex]\frac{x^2}{a^2}[/tex] + [tex]\frac{y^2}{b^2}[/tex] = 1
Multiply through by a²b² to clear the fractions
b²x² + a²y² = a²b² ( subtract a²y² from both sides )
b²x² = a²b² - a²y² ( divide both sides by b² )
x² = [tex]\frac{a^2b^2-a^2y^2}{b^2}[/tex] ( take the square root of both sides )
x = ± [tex]\sqrt{\frac{a^2b^2-a^2y^2}{b^2} }[/tex]
In formula x²/a²+y²/b²=1
Value of x as subject, x = ± [a√(b² - y²)]/b
What is equation?Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side.
Given equation,
x²/a² + y²/b² = 1
moving y²/b² to right side
x²/a² = 1 - y²/b²
multiplying a² on both sides
a². x²/a² = a². 1 - a². y²/b²
Simplifying
x² = a² - a²y²/b²
x = ± √(a² - a²y²/b²)
x = ± a√(1 - y²/b²)
x = ± [a√(b² - y²)]/b
Hence, value of x = ±[a√(b² - y²)]/b in formula x²/a² + y²/b² = 1

Answers
Answer:
484 : 1
Step-by-step explanation:
We can write white blood cells to:
22^5 = 22 × 22 × 22 × 22 × 22
We can write red blood cells to:
22³ = 22 × 22 × 22
Thus, white : red equals
22 (5 times) : 22 (3 times)
22² : 22^0 = 484 : 1
I hope this helps you :)
The required ratio of white blood cells to red blood cells is 1:484.
What is the Ratio?The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.
Here,
A cubic millimeter of blood contains 22³, white blood cells, and 22⁵ red blood cells.
The ratio of white to red blood cell is given as,
Ratio = 22³/22⁵
Ratio = 1 / 484
Thus, the required ratio of white blood cells to red blood cells is 1:484.
