What is the solution of the equation (4x + 3)^2 = 18?

x= .31066 rounded to .31

Step-by-step explanation:

first you take out the exponent (2) by getting the square root of 18 so the equation will be 4x+3=18squared rooted. the primary factors of 18 are 2*3 squared. so instead of 18 put the factors is.so now you will get

4x+3=3^2*2 square rooted.

then you apply the radical rule so square root each of the digits.that will simplify to 4x=3square rooted by 2 divide by 4 on both sides minus 3/4 and if you simplify it should give you the answer

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)
