[tex]9x^2 - 30xy + 25y^2 = (3x)^2 - 2 (15xy) + (5y)^2[/tex]
[tex]= (3x)^2 - 2(3x \times 5y) + (5y)^2\\\\[/tex]
[tex]This \ is \ of \ the \ form \ a^2 - 2ab + b^2 , \ that \ is \ (a-b)^2\\\\a = 3x, \ b = 5y[/tex]

Which expression represents the series 1+5+25+125+625
Answer:
[tex]1 = {5}^{0} [/tex]
[tex]5 = {5}^{1} [/tex]
[tex]25 = {5}^{2} [/tex]
[tex]125 = {5}^{3} [/tex]
[tex]625 = {5}^{4} [/tex]
option A is correct, it starts with the power of zero (equals always one, see it as
[tex] \frac{5}{5} [/tex]
and it goes up to the power of 4
Letter D thanks for asking for help
How do I solve this. Please help!!
Answer:
x = 4[tex]\sqrt{2}[/tex]
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin45° = [tex]\frac{1}{\sqrt{2} }[/tex] , then using the upper 45°
sin45° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{4}{x}[/tex] = [tex]\frac{1}{\sqrt{2} }[/tex] ( cross- multiply )
x = 4[tex]\sqrt{2}[/tex]

Find the circumcenter of a triangle ABC with vertices at A(2, 2), B(0, -4), and C(7, -1)
20 POINTS PEOPLE
Answer:
just sum up the 3 sides.
quick side note: I lost my previews writing bc I waited too long too post it :(
but long story short: you get the length of, say, AB by using pythagoras theorem.
[tex] \sqrt{ {2}^{2} + {6}^{2} } [/tex]
do this with BC and CA too
the 2 is just the distance in x-direction and the 6 is just the distance in y-direction
and since a²+b²=c², we need to take the root to get the distance between 2 points
see screenshot for summing up the three distances. the part out of screen is written out above
the sum is 21.011 length units
hope it helps. have a nice day.

Answer: the slope of green line = [tex]-\frac37[/tex]
Step-by-step explanation:
We know that,
If two lines are parallel then their slopes(rate of change of y with respect to x) are equal.
Given: The red line and the green line are parallel.
The slope of red line = [tex]-\frac37[/tex]
Then, the slope of green line = [tex]-\frac37[/tex] [Slopes of two parallel lines are equal]
Hence, the slope of green line = [tex]-\frac37[/tex]
Chang knows one side of a triangle is 13 cm. Which set of two sides is possible for the lengths of the other two
sides of this triangle?
5 cm and 8 cm
6 cm and 7 cm
7 cm and 2 cm
8 cm and 9 cm
Answer:
8 cm , 9cm
Step-by-step explanation:
sum of any two sides >third side
difference of any two sides<third side
only 8 cm and 9 cm satisfies it
8+9=17>13
9-8=1<13
The width of an extra large rectangle poster is 8 inches more than half its length.The area of this poster is 306 square inches
Answer:
a² + 16a - 612 = 0
Step-by-step explanation:
Here is the complete question :
The width of an extra large rectangle poster is 8 inches more than half its length. The area of this poster is 306 square inches
Write an equation in one variable that could be used to find the number of inches in the dimensions of this poster.
Area of a rectangle = length x width
Let length = a
width = 8 + 1/2a
Area = (8 + 1/2a) x a
306 = (8 + 1/2a) x a
multiply both sides of the equation by 2
612 = 16a + a²
a² + 16a - 612 = 0
the dimensions of the poster can be determined using quadratic formula

Calcula la diagonal de los siguientes cuadrados, cuyos lados tienen las siguientes medidas en centimetros (dibuja los cuadrados): El lado mide 4 cm
Answer:
La diagonal de este cuadrado mide 5.66 cm
Step-by-step explanation:
Primero debemos recordar el teorema de Pitágoras:
Para un triángulo rectángulo, la suma de los cuadrados de los catetos es igual al cuadrado de la hipotenusa.
Ahora si tenemos un cuadrado, lo podemos separar en dos triángulos rectángulos, tal que la hipotenusa de esos triángulos es la diagonal del cuadrado.
(Abajo hay una imagen donde se puede ver esto)
en este caso, tenemos un cuadrado con 4cm de lado.
Entonces cuando armemos el triángulo rectángulo, vamos a tener dos catetos de 4cm de largo, usando el teorema de Pitágoras obtenemos:
(4cm)^2 + (4cm)^2 = D^2
Queremos resolver esto para D.
16cm^2 + 16cm^2 = D^2
32cm^2 = D^2
√(32cm^2) = √(D^2) = D
5.66 cm = D
La diagonal de este cuadrado mide 5.66 cm
calculate the value of 3√12 ÷ 6√27

Answer:
[tex]x = \frac{9}{13} \ , \ y = - \frac{5}{13}[/tex]
Step-by-step explanation:
3x - 5y = 4 ----------- ( 1 )
9x - 2y = 7 -----------( 2 )
______________________
( 1 ) x 9 => 27x - 45y = 36 ----------------- ( 3 )
( 2) x 3 => 27x - 6y = 21 -------------------( 4 )
_____________________
( 3 ) => 27x - 45y = 36
- ( 4 ) => -27x + 6y = - 21
____________________
( 3 ) - ( 4 ) => 0x - 39y = 15
-39y = 15
[tex]y = \frac{15}{-39} = -\frac{5}{13}[/tex]
Substitute y in ( 1 ) :
[tex]3x - 5y = 4\\\\3x - ( 5 \times -\frac{5}{13}) = 4\\\\3x + \frac{25}{13} = 4\\\\3x = 4 - \frac{25}{13}\\\\3x = \frac{52 - 25}{13}\\\\3x = \frac{27}{13}\\\\x = \frac{27}{13 \times 3}\\\\x= \frac{9}{13}[/tex]
80 25 x pls help me with this one
Answer:
25
Step-by-step explanation:
Answer:
x = 25
Step-by-step explanation:
Okay so as you can see there is an x shape and whenever you have that it means they are verticle angles. So we can conclude that 25 is verticle to x and so x is equal to 25.

Answer:
a] 4 ft, 6 ft, 11 ft
the sum of short side is (4+6)=10 which is less than the sum of the longest side. Therefore we conclude that the three lengths CANNOT make a triangle:
Answer: CANNOT make a triangle
b] 5 ft, 7 ft, 11 ft
sum of shorter sides is (5+7)=12
since 12 is greater than 11, then the three length can make a triangle.
Answer: CAN make a triangle
c] 7 ft, 8 ft, 14 ft
The sum of shorter side is:
(7+8)=15 ft
since the sum of shorter side is longer than that of the longer side, we conclude that the three lengths can form a triangle.
Answer: CAN make a triangle
