Answer: 25
Step-by-step explanation: 350=35*10=7*5*5*2=14*5^2
Answer:
dont know true or not..9*12*18/3 = 648
<span>Let the number be x
then x + 12(1/x) = 7
x + 12/x = 7
x² + 12 = 7x
x² - 7x + 12 = 0
(x - 4)(x-3) = 0
x = 4 or x = 3
Then the numbers are 3 & 4.
I hope this helps you out! :)

Answer:
We will transform the equation to the vertex form:
y = x² + 8 x + 12 = x² + 8 x + 16 - 16 + 12 =
= ( x + 4 )² - 4
Vertex form is: y = a ( x - k )² + h
Vertex coordinates are: ( - 4, - 4 ).
Step-by-step explanation:
The transformer is 27.5 ft above the ground.
Solution:
The given image is like a triangle.
Angle 'L' represents the triangle is right triangle.
Use Pythagoras theorem to find the answer.
Base of the triangle = 12 ft
Hypotenuse of the triangle = 30 ft
Height of the triangle = x
Using Pythagoras theorem,
![\text{Base} $^{2}+$ Height $^{2}=$ Hypotenuse $^{2}$](https://tex.z-dn.net/?f=%5Ctext%7BBase%7D%20%24%5E%7B2%7D%2B%24%20Height%20%24%5E%7B2%7D%3D%24%20Hypotenuse%20%24%5E%7B2%7D%24)
![12^2+x^2=30^2](https://tex.z-dn.net/?f=12%5E2%2Bx%5E2%3D30%5E2)
![144+x^2=900](https://tex.z-dn.net/?f=144%2Bx%5E2%3D900)
Subtract 144 on both sides of the equation.
![x^2=900-144](https://tex.z-dn.net/?f=x%5E2%3D900-144)
![x^2=756](https://tex.z-dn.net/?f=x%5E2%3D756)
Taking square root on both sides.
![x=27.5](https://tex.z-dn.net/?f=x%3D27.5)
Hence the transformer is 27.5 ft above the ground.
