A 135 degree central angle intersects a circle with a radius of 8in what is the length of the intersected arc?

Hell . what are the solutions to `10x^2 - 38x - 8 = 0`? is this when i find the factors and use the numbers within the factors to determine the zeros? i hope that made sense lol

Can some one explain this i got sent this. is this a threat i’m scared

Square a has a side length of (2x-7) and square b has a side length of (-4x+18). how much bigger is the perimeter of square b than square a?and show all work! you so
