Answer:
n-14 ;)
Step-by-step explanation:
The simplified form of the given expression is n-13.
What is an expression?Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.
Given that, an expression, n-4-9, we need to write this expression in the simplest form,
We can add -4 and -9, to write it in the simplest form,
n-4-9
= n-(4+9)
= n-13
Hence, the simplified form of the given expression is n-13.

x - y = 11 and 2x + y = 19 by elimination
Answer:
(14,3)
Step-by-step explanation:
2x + y = 19
x - y = 11
-2(x - y) = -2(11)
-2x + 2y = -22
-2x + 2y = -22 + 2x + y = 19
3y = -3
y = 3
-------------------------------------------------
x - y = 11
x - 3 = 11
x = 11 + 3
x = 14
Two angels of a triangle measure 12 and 40.
What is the measure of the third angle of the triangle ?
Answer:
C) 128
Step-by-step explanation:
Sum of all three angles of triangle = 180
Let the third angle be 'x'
x + 12 + 40 = 180
x + 52 = 180
x = 180 - 52
x = 128

A(X)=(3x-2)^2-(2x-3)^2
Answer:
5(x - 1)(x + 1)
Step-by-step explanation:
A(x) = (3x - 2)² - (2x - 3)² = (3x - 2 + 2x - 3)[3x - 2 - (2x - 3)] = 5(x - 1)(x + 1)

ABCD is a square
=> Δ ABD is a isosceles right triangle at A
using pythago theorem, we have:
AB² + AD² = BD²
=> 2AD² = 4
⇔ AD² = 2
⇒ AD = √2
through O, draw EF parallel to AD and BC
=> EF is diameter
because EF//AD => EF = AD = √2 (because circle O is inscribed the square ABCD)
=> the area of the circle is [tex]S=\frac{(\sqrt{2})^{2} }{4}.\pi =\frac{\pi }{2}[/tex]

what is the slope of line segment 7 ?
——PLEASEE HELP.!! ILL GIVE BRAINLIEST.!! *EXTRA POINTS* DONT SKIP:((———
Answer:
The slope is 0 because it is a straight line
Step-by-step explanation:
Answer:
undefined.
Step-by-step explanation:
You could be really formal and use the slope formula
The y values are both the same -- 4.
The x values are 3.5 and 6.5
Therefore the slope is (6.5 - 3.5) / (4 - 4)
The denominator is 0
The slope is undefined because 3/0 is not very well behaved.
A horizontal line always gives an undefined amount.
a) The y-intercept of the line with the largest slope
is _____
b) For the two lines with a negative slope, the difference
in the value of their x-intercepts is _____
c) For the line with the y-intercept -3, its equation in
slope-intercept form is ____
d) For the line with a slope of 2, the input of _____
gives an output of 17
Answer:
a) the largest y-intercept is 1
b) 13.5
c) y=x-3
d) 8
Step-by-step explanation:
the question was worded very strangely and I will answer the way I precieved it.
for question d, I simply considered the question to be asking what is X when y is 17 and since the equation of that line is 2x-1

The perimeter of a triangle is 43 inches. The second side is 4 times as long as the first side. The third side is 1 inch longer than the first side. What is the length of each side
Answer:
First side=7
Second side =28
Third side =8
explanation:
Perimeter of a triangle is the sum of the length of the sides of the triangle. Given that the perimeter of the triangle = 43 inches
Second side is 4 times the first side
Third side is 1 inch longer the first
Let's call the first side x
Then equation for the perimeter of the triangle is given by
x+4x+x+1=43
We solve for x
6x+1=43
6x=43-1
6x=42
x=42/6
x=7
Therefore the first side x=7, the second side is 4x= 4*7=28, third side= 1+x= 1+7=8

solve for the variable
7x = 49
-4x= -40
x/2 = 6
x/9 = -2
Answer:
71012-18Step-by-step explanation:
For 7x = 49 you need to divide 7 to both sides
For -4x=-40 you need to divide -4 to both sides
For x/2 = 6 you need to multiply 2/1 to both sides
For x/9 =- 2 you need to multiply 9/1 to both sides
