Answer:
See below
Step-by-step explanation:
The square root of a number is defined as ![\pm y=\sqrt[2]{x}](https://tex.z-dn.net/?f=%5Cpm%20y%3D%5Csqrt%5B2%5D%7Bx%7D)
where 
gives the original number. For example, 
because 
and 
.
For one set the two equations equal to eachother and solve from there. 2 is 45
For three set the two equations equal. Same for four
Answer:
3rd option
Step-by-step explanation:
The equation of a parabola in vertex form is
f(x) = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k ) = (- 1, - 25 ) , then
f(x) = (x - (- 1) )² - 25 , that is
= (x + 1)² - 25 ← expand using FOIL
= x² + 2x + 1 - 25
= x² + 2x - 24
Answer:
Step-by-step explanation:
Let the first number = x
Let the second number = x + 9
Let the third number = 4x
Together they make 123
x + x + 9 + 4x = 123 combine the left
6x + 9 = 123 Subtract 9 from both sides
6x = 123 - 9
6x = 114 Divide by 6
x = 114/6
x = 19
=================
First number = 19
Second number = 19 + 9 = 28
Third number = 4*19 = 76
The denominator is the one on the bottom so 9 is the denominator the top is the numerator
