Step-by-step explanation:
(3 × 10) × 8 = 3 × (10 × 8)
It's an Associative Property of addition:
<em>(a + b) + c = a + (b + c)</em>
<em></em>
Check it:
Left side: (3 × 10) × 8 = 30 × 8 = 240
Right side: 3 × (10 × 8) = 3 × 80 = 240
CORRECT
Answer:
8,5 feet
Step-by-step explanation:
The equation of the form
x² + y² = (r)²
Is the equation of the circumference
We have for the pool:
x² + y² = 2500 ⇒ x² + y² = (50)²
And for the outside edge of the footpath
x² + y² = 3422,25 ⇒ x² + y² = (58,5)²
So we obtain the radius of each circumference
For the outside edge of the pool r₁ = 50 feet
For the outside edge of the footpath r₂ = 58,5 feet
Then the width of the footpath is 58,5 - 50 = 8,5 feet
Răspuns:
64 cm
Explicație pas cu pas:
Perimetrul fiecărei margini a unui cub:
4 * lungime laterală
Lungime laterală = 16cm
Prin urmare, perimetrul va fi:
4 * 16cm
= 64cm

6t-13t+18t6t-13t+18t6t-13t+18t
When you multiply two negative numbers it will be possitive. A way to know that is if there is an even number of negatives its posistive here we have 2 negative numbers and 2 is an even number sooooooo it is a positive! Hope this helps and have a great day!
