Answer:
[tex]\sqrt{(n-m)(n+m)}[/tex] & [tex]-\sqrt{(n-m)(n+m)}[/tex]
Step-by-step explanation:
1) Subtract [tex]m^{2}[/tex] from both sides. This should leave you with [tex]x^{2}=n^{2}-m^{2}[/tex].
2) Square root both sides. This should leave you with [tex]x=\sqrt{n^2-m^2}[/tex] & [tex]x=-\sqrt{n^2-m^2}[/tex].
You can stop here if this is what the problem is asking for. However, it is not fully simplified.
3) Factor the equation. This should leave you with [tex]\sqrt{(n-m)(n+m)}[/tex] & [tex]-\sqrt{(n-m)(n+m)}[/tex].
[tex]\boxed{\left \{ {{\sqrt{(n-m)(m+n)}} \atop {-\sqrt{(n-m)(m+n)}}} \right.}[/tex]
Solution Steps:- Steps using the quadratic formula -______________________________
1.) Subtract n² from both sides:[tex]n^2-n^2=0[/tex][tex]m^2-n^2=m^2-n^2[/tex]2.) Rewrite:This equation is in standard form: ax² + bx² + c = 0. Substitute 1 for a, 0 for b, and (m-n) (m+n) for c in the quadratic formula, [tex]\frac{-b\frac{+}{}\sqrt{b^2-4ac} }{2a}[/tex]:
[tex]x^2+m^2-n^2=0[/tex]2.a) Turns into:
[tex]x=\frac{0\frac{+}{}\sqrt{0^2-4(m-n)(m+n)}}{2}[/tex]3.) Square 0:[tex]0^2=0[/tex] (Also means it Cancels out.)4.) Take the square root of −4(m−n)(m+n):This just means combine them by squaring.
[tex]-4^2=2[/tex] (Half it, don't square it.)[tex](m-n)(m+n)^2=(n^2-m^2)[/tex]4a.) Our equation should look like this now:
[tex]x=\frac{0\frac{+}{}2\sqrt{(n^2-m^2)}}{2}[/tex]5.) Solve the equation using ±:Solve the equation [tex]x=\frac{0\frac{+}{}2\sqrt{(n^2-m^2)}}{2}[/tex]:
5a.) Solve the equation when ± is plus:
[tex]x=\sqrt{(n-m)(m+n)}[/tex]5b.) Solve the equation when ± is minus:
[tex]x=-\sqrt{(n-m)(m+n)}[/tex]______________________________

A middle school mathematics teacher except a teaching position that pays 40,000 per year, each year the expected raise is $2000. How much total money with this teacher and teaching middle school math Mathematics over the first 30 years?
9514 1404 393
Answer:
$2,070,000
Step-by-step explanation:
The series of salaries has a first term of $40,000 and a common difference of $2,000. The sum of them is given by the formula ...
Sn = (2a1 +d(n -1))(n/2)
where a1 is the first term of the series, d is the common difference, and n is the number of terms.
In this problem, we have ...
a1 = 40,000; d = 2,000; n = 30
so the sum is ...
S30 = (2(40,000) +2,000(30 -1))(30/2) = (80,000 +58,000)(15)
S30 = 2,070,000
The teacher will earn $2,070,000 over 30 years on this salary schedule.

A pencil case for £3.99 a packet of pens for £2.49 a calculator for 4.99 she pays with a £20 note how much change will she receive
Answer:
£20 - ( 2.49 + 4.99 + 3.99)
= 20 - 11.47
= £8.53.
Step-by-step explanation:
Answer:
She will recive £ 8.53 in change.
Step-by-step explanation:
£3.99 + £2.49 + £4.99 = £11.47
^ (All the prices combined to subtract later)
£20.00 - £11.47 = £8.53
^( You would subtract £11.47 from £20.00 to find out the change)

What is the axis of symmetry for the following equation?
y=4x2-8x+9
Answer:x=1
Step-by-step explanation:
The x of the top of the parabola is:
x=-(-8)/(2*4)=1
x=1
Using quadratic function concepts, it is found that the axis of symmetry for the function is x = 1.
The standard quadratic function is modeled by:
[tex]y = ax^2 + bx + c[/tex]
And has axis of symmetry given by:
[tex]x = -\frac{b}{2a}[/tex]
In this problem, the function is:
[tex]y = 4x^2 - 8x + 9[/tex]
The coefficients are:
[tex]a = 4, b = -8, c = 9[/tex]
Then, the axis of symmetry is:
[tex]x = -\frac{b}{2a} = -\frac{(-8)}(2(4)} = 1[/tex]

A garden is in the shape of a rectangle 90 m by 60 m.
Flowers are grown in 40% of the garden.
The rest of the garden is grass.
Work out the area of the garden that is grass.
Answer:
3240 sq meters
Step-by-step explanation:
Area of garden = 90*60= 5400 square meters.
Flowers grown on = 40%
So, grass grown on = (100 -40)% = 60%
60% of 5400 = 0.6*5400 = 3,240.
So, the area of the garden that is grass = 3,240 square meters

What is an algebraic expression?An Algebraic expression shows the expression of variables with numbers. The purpose of an algebraic expression is to determine the unknown variable represented by an unknown letter.
From the given information:
2(6x + 4) - 6 + 2x = 3(4x + 3) + 1
Open brackets
12x + 8 - 6 + 2x = 12x + 9 + 1
Collect like terms
12x + 2x - 12x = -8 + 6+9 + 1
14x - 12x = -8 + 16
2x = 8
x = 8/2
x = 4

Regional erosion occurs at a rate of 2 m per 1,000 years.
How much regional erosion will occur over 1,000,000 years?
A) 20 m
B) 200 m
C) 2,000 m
D) 100,000 m
Answer:
200
Step-by-step explanation:
It's 200 because you would take the 1,000 and multiply it by the power of 3, which is 100,000. So therefore you would do the same thing with the 2, which 2 to the power of 3 is 200. There is your explanation.
