What is the Square of the perimeter of a square?
perimeter of a square is 4x square that term (4x)(4x)and it gives you 16x2
If a square has a perimeterof 48 inches. how long is each side?
Each side would be 12 inches long. Here's why: * A square has 4 equal sides. * Therefore, we can set up an equation 4x=48 because four sides times an unknown length (x) make the perimeter (4x is the same as x+x+x+x). *So, we would divide both sides of 4x=48 by 4 to isolate x on its own * 48/4=12. x=12 inches!
What is the square root of 4x-8x plus 9?
4x-8x = -4x √-4x stands. However, x could not possibly be a positive number, because: (Negative) X (Positive) = (Negative) The square root of a negative number is undefined-so... (√-4x) + 9 Is your answer.
How do you Factor 8x square - 10x - 7?
(2x + 1)(4x - 7)
Why is brayani wrong when she says when x equals 3 the value of 4x squared is 36?
She isn't. 4x squared is 4 times (x squared). That is, 4 times (3 squared) = 4 times 9. If you want it to be the square of 4x (which would be the square of 4 times 3, ie, 12), you have to write it as (4x)squared.
