john is placing cement tiles for a patio in a rectangle surrounding a rectangular fire pit. The fire pit has a width of x ft and a length that is 5 times the width. The entire patio is 6ft wider and 19 ft longer than the fire pit. What is the area that he will need to buy tiles for?

49x + 114

Step-by-step explanation:

[   [ fireplace ] x   = area of 5                   ]  x + 6

     5x

   patio               = area of 5 + 49x + 114

5x + 19

(5x + 19) ( x + 6) = 5 + 19x + 30x + 114

(5 + 49x + 114)                     -   (5 )                         =           49x + 114

(area of patio and fireplace) - (area of fireplace)     =       (area of patio only)

false

step-by-step explanation:

4y - 6 + 4y^2 - 9

before simplifying this contains 4 terms

after simplifying

4y -15 + 4y^2

it contains 3 terms

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
