(4x-1)²-(4x-3) x (16x²+3)

-64x^3 +64x^2-20x+10

Step-by-step explanation:

simplify, distribute

(btw, the little arrow sign means a exponent)

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer

step-by-step explanation:

the answer is y = 11.54

hope this : )
