Ben bought a white plastic shelf that was 6.35 feet long. He also bought a brown plastic shelf that was 2.085 feet long. How much-combined feet of shelving did Ben buy?

combined feet of shelving = 8.435 feet

Step-by-step explanation:

To find the combined feet of shelving, we simply add the two lengths of the shelvings:

1. white plastic shelf = 6.35 feet long

2. brown plastic shelf = 2.085 feet long

combined feet of shelving = 6.35 + 2.085 = 8.435 feet

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)

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
