Answer:
(16)(1) => identity property of multiplication
2(3+7) = 2(3) + 2(7) => distributive property
(2+6) + 3 = 2+ (6+3) => associative property
9+0 = 9 => identity property of addition
8 x 4 = 4 x 8 => commutative property
How many cubic feet are in a carton measuring 6 feet, 8 inches by 3 yards by 4.5 inches?
Answer:
9
Step-by-step explanation:
Equation
Sum = s = 180*(n - 2)
Solution
1260 = 180*(n - 2) Divide by 180
1260 / 180 = 180 * (n -2 ) / 180
7 = n - 2 Add 2 to both sides
9 = n
Answer
The polygon has 9 sides.
Answer:
x=10/-3, 4/5
Step-by-step explanation:
f(x) = (10 - 3x)(4 - 5x)
10-3x=0
-3x=-10
x=10/3
4 - 5x = 0
-5x = -4
x = 4/5
