Answer:

d=4√2

Step-by-step explanation:

distance formula = √(x2-x1)²+(y2-y1)²

d=√(4-8)²+(-7-(-3))²

Varvara68 [4.7K]

Answer:

Width 2 4 6 8

Area 10 20 30 40

Step-by-step explanation:

Area of a rectangle = length × width

Calculate width when length = 5 inches

When length = 5 inches and width = 2 inches

Area of a rectangle = length × width

A = 5 × 2

= 10 square inches

When length = 5 inches and width = 4 inches

Area of a rectangle = length × width

A = 5 × 4

= 20 square inches

When length = 5 inches and width = 6 inches

Area of a rectangle = length × width

A = 5 × 6

= 30 square inches

When length = 5 inches and width = 8 inches

Area of a rectangle = length × width

A = 5 × 8

= 40 square inches

Given the same length and different width

Width 2 4 6 8

Area 10 20 30 40

Compare using <, >, or =. 7 2/5___ 7 3/8
katrin [286]

Answer:

<

Explanation:

Step 1 - Convert the mixed numbers into decimals

7 2/5

2/5 • 20/20 = 40/ 100

40/ 100 = 0.4

0.4 + 7.0 = 7.4

Therefore, 7 2/5 = 7.4

Step 2 - Convert the mixed numbers into decimals

7 3/8

3/ 8 = 0.375

0.375 + 7.0 = 7.375

Therefore, 7 3/8 = 7.375

Step 3 - Compare

7.4 < 7.375

So, 7 2/5 is less than 7 3/8
