If I had the equation, x^2=49, what would my solution or solutions be and why?

x=7 and or x=-7

Step-by-step explanation:

for this case we have that by definition, the volume of a cylinder is given by:

where:

r: it's the radio

h: it's the height

we have as data that:

substituting:

so, the cylinder volume is

option d

you have to find the same variables -3n - 5n so this would be -3n +(-5n) which equals -9n
