Step-by-step explanation:
a^2 + b^2 = c^2
(x+2)^2 + 4x^2 = (3x+4)^2
(x+2)(x+2)+ 4x^2= (3x+4)(3x+4)
x^2 + 2x + 2x + 4 + 4x^2 = 9x^2 + 12x + 12 x + 16
5x^2 + 4x + 4 = 9x^2 + 24x + 16
-4x^2 - 20x - 12 = 0
now we can use the quadratic formula
(-b±√(b²-4ac))/(2a)
I can't type all this so
.....
x = -0.697224362 or -4.302775638
AB can't be negative so it's the first one
so it's equals to 1.302775638

Answer:
Option D, 15 and 10
Step-by-step explanation:
<u>Step 1: Convert the words into an expression</u>
A number is 5 less than 2 times another number. Their sum is 25.
<em>2x - 5 = 25</em>
<em />
<u>Step 2: Solve for x</u>
2x - 5 + 5 = 25 + 5
2x / 2 = 30 / 2
<em>x = 15</em>
<em />
