Answer:

A) 8w=80; 10

Step-by-step explanation:

Let w = width

L = 3w

Fencing is perimeter

P=2(l+w)

80 = 2(3w+w)

80 = 2(4w)

80 = 8w

Divide each side by 8

80/8 = 8w/8

10 = w

Prove 2√(x) + 1/√(x + 1) <= 2√(x+1) for all x in [0,inf)
EleoNora [17]
Start by multiplying each side of the inequality by \sqrt{x + 1} and simplifying:

2 \sqrt x + \frac{1}{\sqrt{x+1}}  \leq  2 \sqrt{x + 1}
(2 \sqrt x + \frac{1}{\sqrt{x+1}})(\sqrt{x + 1}) \leq (2 \sqrt{x + 1})(\sqrt{x + 1})
2 \sqrt{x(x + 1)} + 1 \leq 2(x + 1)
2 \sqrt{x^2 + x} + 1 \leq 2x + 2
2 \sqrt{x^2 + x} \leq 2x + 1
\sqrt{x^2 + x} \leq x + \frac{1}{2}

From here, we can square both sides to get

x^2 + x \leq (x + \frac{1}{2})^2
x^2 + x \leq x^2 + x + \frac{1}{4}
0  \leq \frac{1}{4}, which is always true.

labwork [276]

There are 180 school days in a year. How many school days are in 5 years?

If we know that there are 180 school days in 1 year, we can multiply 180 by 5 to get our answer of how many school days are in 5 years.

900 school days in 5 years.
