Which value of x is a solution to x2 = 16? PLEASE HURRY! I AM IN THE MIDDLE OF A TEST! I WILL MARK AS BRAINLIEST IF CORRECT!

Which data set has a greater spread? why? set a: {38, 12, 23, 48, 55, 16, 18} set b: {44, 13, 24, 12, 56} has a greater spread because .

Follow these steps using the algebra tiles to solve the equation −5x + (−2) = −2x + 4. 1. add 5 positive x-tiles to both sides and create zero pairs. 2. add 4 negative unit tiles to both sides and create zero pairs. 3. divide the unit tiles evenly among the x-tiles. x =

Solve this equation using substitution. {4x + y = −2} {4x + 6y = 44}
