What is the solution to x2 = 225?
o
a. x = 15 or x =
-15
o b. x = -15
oc. i = 15
d. r = 5 or x = -:
dan

x = ± 15

Step-by-step explanation:

Given

x² = 225 ( take the square root of both sides )

x = ± = ± 15

That is x = - 15 0r x = 15

Step-by-step explanation:

X² = 225

Finding the square root of both side

√X² = √225

X = 15 or -15

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
