Which equation has the same solution as x^2+15+6=-2 ? A. (x+7.5)^2=48.25
B. (x-7.5)^2=-64.25
C. (x-7.5)^2=48.24
D. (x+7.5)^2=64.25

the answer for this question is A. (x+7.5)^2=48.25

Step-by-step explanation:

(x+7.5)^2=48.25

x^2 + 7.5x + 7.5x + (7.5^2) = 48.25

x^2 + 15x + 56.25 =48.25

x^2 + 15x + ( 56.25 - 48.25 ) = 0

x^2 + 15x + 8 = 0

and you forget to put 'x' at 15 on the question

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
