im am pretty sure it is b.sometimes because an equation can have more then one answer
Answer:
1/2
Step-by-step explanation:
(y2-y1)/(x2-x1) is the equation for finding slope with two given points
-5-(-2) over 3-9 equals
-3/-6=-1/-2=1/2
Answer:
The communicative property for multiplication states that the order of the multiplicands and can be swapped and the resulting product stays the same.
So
A * B = B * A
So if
7*8=56
then the commutative property says
8*7=56 as well since you can swap the order of the terms on the left and not change the result.
This property is true for addition and multiplication. It does not hold for subtraction or division.
Hope that makes sense and helps. (:
The length of the yard is 25ft.
In order to find this we first need to set up variables for the length and the width. Since we don't know anything about the width, we'll set it as x. Then, we know the length is equal to ten more than three times the width. Since the width is x, we can write the length as 3x + 10. Now we can use the formula for the perimeter of a rectangle to solve for x.
2l + 2w = P
2(3x + 10) + 2(x) = 60
6x + 20 + 2x = 60
8x + 20 = 60
8x = 40
x = 5
Now that we have a value for x, we can plug into the length equation and find the length.
3x + 10
3(5) + 10
15 + 10
25
Answer:
1: 8a²
2: 9a²b²c²
Step-by-step explanation:
1: 48a³ ÷ 6a
48÷6 = 8
8a²
2: 72a³b⁴c⁵ ÷ 8ab²c³
72÷ 8 =9
9a²b²c²
