The legs of a right triangle are 12 centimetres and 16 centimeters. What is the length of the hypotenuse?
Answer:
20 cm
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse h is equal to the sum of the squares on the other 2 sides, that is
h² = 12² + 16² = 144 + 256 = 400 ( take the square root of both sides )
h = [tex]\sqrt{400}[/tex] = 20

Answer:
The answer is -1/9
Step-by-step explanation:
The slope of a perpendicular line is the opposite reciprocal.
To find the slope you take the given slope (9) and flip the reciprocal which results it turning into 1/9.
Then make it the opposite value. Like switching a negative to a positive or a positive to a negative. For this case, you make 1/9 into a -1/9

n = 5(m² + D)
Solve for D
Answer:
D = [tex]\frac{n-5m^2}{5}[/tex]
Step-by-step explanation:
Given
n = 5(m² + D) ← distribute
n = 5m² + 5D ( subtract 5m² from both sides )
n - 5m² = 5D ( divide both sides by 5 )
[tex]\frac{n-5m^2}{5}[/tex] = D
The solution of the expression for the value of D will be D = (n - 5m²) / 5
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given expression is n = 5(m² + D). The value of D will be calculated as below:-

Show that (x-1)(x+2)(x+3) can be written in the form ax^3+bx^2+cx+d where a,b and c are all positive integers, and d is a negative integer
Answer:
The answer is x³ + 4x² + x - 6.
Step-by-step explanation:
You have to expand it :
[tex](x - 1)(x + 2)(x + 3)[/tex]
[tex] = ( {x}^{2} + 2x - x - 2)(x + 3)[/tex]
[tex] = ( {x}^{2} + x - 2)(x + 3)[/tex]
[tex] = {x}^{3} + 3 {x}^{2} + {x}^{2} + 3x - 2x - 6[/tex]
[tex] = {x}^{3} + 4 {x}^{2} + x - 6[/tex]
The expression (x - 1) (x + 2) (x + 3) is written in form of ax³ + bx² + cx + d as;
⇒ (x - 1) (x + 2) (x + 3) = x³ + 4x² + x - 6
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is;
⇒ (x - 1) (x + 2) (x + 3)
Now, It can be solve by multiplying as;
The expression is;
⇒ (x - 1) (x + 2) (x + 3)
⇒ (x - 1) (x² + 3x + 2x + 6)
⇒ (x - 1) (x² + 5x + 6)
⇒ x³ + 5x² + 6x - x² - 5x - 6
⇒ x³ + 4x² + x - 6
Thus, By comparing with the equation of the form ax³ + bx² + cx + d , we get;
⇒ a = 1 , b = 4 , c = 1 and d = -1
Clearly, a, b and c are positive integers, and d is negative integer.
Hence, The expression (x - 1) (x + 2) (x + 3) is written in form of
ax³ + bx² + cx + d.

ShayAnn is a high school junior who is working on saving money for college. At the beginning of her sophomore year, she made the goal of saving $2,000 each school year for a total of $6,000 by the beginning of her freshman year of college. Six months into her junior year of high school, ShayAnn is evaluating the progress she has made toward her goal. So far, she has saved $2,000. To make her original goal of $6,000, how much does ShayAnn need to save each month for the next 18 months (round to two decimal places if needed)? no
Answer:
The amount, she needs to save each month for the remaining 18 months is $222.22
Step-by-step explanation:
The given information are;
The amount ShayAnn intends to save each year = $2,000
The total amount ShayAnn plans on saving = $6,000
The amount ShayAnn had saved six months into her junior year = $2,000
The number of months remaining for her to save towards her goal = 18 months
The amount she needs to save each month for the next 18 months to make her goal of $6,000 is given as follows;
The amount remaining to make her original goal = $6,000 - $2,000 = $4,000
The amount, X, she needs to save each month for the remaining 18 months is therefore;
X = (The amount remaining to make her original goal)/(The number of months remaining for her to save towards her goal)
X = $4,000/(18 months) = [tex]\$ 222.\overline 2[/tex]
∴ The amount, she needs to save each month for the remaining 18 months = $222.22.

5x minus 6 equal 44?
Answer:
x = 10
Step-by-step explanation:
I'm not entirely sure what you're asking, however we know that:
5x-6=44
5x must be 50, as 50-6=44
50 divided by 5 is 10, so 10x
Answer:
x=10
Step-by-step explanation:
Add 6 to both sides.
5x=44+6
Add 44 and 6 to get 50.
5x=50
Divide both sides by 5.
x= 50/5
Divide 50 by 5 to get 10.

1/2 (-10x + 4) = -4 (-3+2x) +8
Answer:
[tex]x=6[/tex]
Step-by-step explanation:
[tex]\frac{1}{2} (-10x+4)=-4(-3+2x)+8[/tex]
To make things easier, let's first start by rewriting [tex]\frac{1}{2}[/tex] as a decimal:
[tex].5(-10x+4)=-4(-3+2x)+8[/tex]
Distribute [tex].5[/tex] into [tex](-10x+4)[/tex]:
[tex]-5x+2=-4(-3+2x)+8[/tex]
Distribute [tex]-4[/tex] into [tex](-3+2x)[/tex]:
[tex]-5x+2=12-8x+8[/tex]
Combine like terms:
[tex]-5x+2=20-8x[/tex]
Add [tex]8x[/tex] to both sides of the equation:
[tex]3x+2=20[/tex]
Subtract [tex]2[/tex] from both sides of the equation:
[tex]3x=18[/tex]
Divide both sides of the equation by the coefficient of [tex]x[/tex], which is [tex]3[/tex]:
[tex]x=6[/tex]
_
Check your work by substituting [tex]6[/tex] into the initial equation:
[tex].5(-10(6)+4)=-4(-3+2(6))+8[/tex]
[tex].5(-60+4)=-4(-3+12)+8[/tex]
[tex]-30+2=12-48+8[/tex]
[tex]-28=-28[/tex]
The answer is correct!
Answer:
x = 6
Step-by-step explanation:
We know that,
( + ) × ( + ) = ( + )
( - ) × ( - ) = ( + )
( - ) × ( + ) = ( - )
Let us solve it now.
[tex]\sf \dfrac{1}{2} (-10x+4)=-4(-3+2x)+8[/tex]
Solve the brackets.
[tex]\sf -\dfrac{10x}{2} +\dfrac{4}{2} =+12-8x+8\\\\\sf -5x +2 =20-8x[/tex]
Add 8x to both sides.
[tex]\sf -5x+8x+2=20\\\\3x+2=20[/tex]
Subtract 2 from both sides.
[tex]\sf 3x=20-2\\\\3x=18[/tex]
Divide both sides by 3.
x = 6
