Answer:
3.16 ≈ 3.2
Step-by-step explanation:
Put the numbers in the distance formula and do the arithmetic.
d = √((x2 -x1)² +(y2 -y1)²)
d = √((2-(-1))² +(3-2)²) = √(3² +1²) = √10
d ≈ 3.16 ≈ 3.2
The distance rounded to hundredths is 3.16. Rounded to tenths, it is 3.2.
The formula for perimeter is 2L + 2W and the formula for the area is L * W, since we don't know the width we will divide 35:7 = 5 and he the measurement for the width.
Now just add L + W = 12 and multiply by 2 the answer is 24
Or 2 * 7 + 2 * 5 = 24

Answer: 1 < x < 25
<u>Step-by-step explanation:</u>
The sum of two sides must be GREATER than the third side.
a + b > c a + c > b b + c > a
12 + 13 > x 12 + x > 13 13 + x > 12
25 > x x > 1 x > -1
x < 25 1 < x
Length cannot be negative so disregard x > -1
We are left with 1 < x and x < 25
1 < x < 25
