Answer:

40 ft

Step-by-step explanation:

Data:

(1) P = 120 ft

(2) l = 2w

Calculations:

(3) P = 2l + 2w Substitute (1) and (2) into (3)

120 = 2(2w) + 2w Multiply

120 = 4w +2w Combine like terms

120 = 6w Divide by 6

(4) w = 20 ft Substitute (4) into (2)

l = 2 × 20

l = 40 ft

Check:

120 = 2×40 + 2×20

120 = 80 + 40

120 = 120

I'm not sure what you want with the first part (3/1=6/2)

well PEMDAS or parenthasees exponents, mult or division whichever comes first, addition subtraction, whichever comes first so

3-1/1 would be divison first
1/1=1
3-1=2

Write the set of real numbers from -10 through 10 in interval notation.

Answer:

$Interval: [-10.10]$

Step-by-step explanation:

Given

Set: -10 to 10

Required

Write as interval notation

We start by writing the given parameter as an inequality

$Inequality: -10 \leq x \leq 10$

The direct representation of $\leq$ and $\geq$ in interval representation of sets is $[$ and $]$ , which shows that the beginning and end of the interval are inclusive;
