Answer:
Anne
Step-by-step explanation:
The expression cannot be simplified anymore, but it can be laid out correctly.
The greatest number for the exponents should come first, so Anne is the one who laid it out correctly.
Hope it helps!!
Let me know if I'm wrong...
Answer:
no enough info
Step-by-step explanation:
5 pairs of gloves, two gloves per pair, so we have 10 gloves.
If the entire pack cost $29.45, we divide that by 10 to determine the cost of a single glove:
$29.45 ÷ 10 = $2.945 which rounds to $2.95 per glove.
It is better to graph these points, to easily understand that the distance of the two points form the hypotenuse of the right triangle. We need to use the Pythagorean theorem to solve for the distance of the two points.
a² + b² = c² ; a = x value ; b = y value
1) (3,8) and (-9,-8)
a = 3 - (-9) = 3 + 9 = 12 ⇒ 12² = 144
b = 8 - (-8) = 8 + 8 = 16 ⇒ 16² = 256 ⇒⇒ 144 + 256 = 400 ; c = √400 = 20
2) (2,6) and (5,2)
a = 2 - 5 = 3 ⇒ 3² = 9
b = 6 - 2 = 4 ⇒ 4² = 16 ⇒⇒ 9 + 16 = 25 ; c = √25 = 5
3) (21,16) and (9,11)
a = 21 - 9 = 12 ⇒ 12² = 144
b = 16 - 11 = 5 ⇒ 5² = 25 ⇒⇒ 144 + 25 = 169 ; c = √169 = 13
