Anew youth sports center youth is being built in pagosa springs. the perimeter of the rectangular playing field is 358 yards. the length of the field is 99 yards less than triple the width. what are the dimensions of the playing field?
the width is ( ) yards
the length is ( ) yards

W = 69.5  L = 109.5

Step-by-step explanation:

L = 3W-99

Perimeter = 2L + 2W

358 = 2(3W-99) + 2W

358 = 6W-198 + 2W

358 = 8W-198

556 = 8W

69.5 = W

e.

step-by-step explanation:

because there are always 10 numbers in a phone number.

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)
