Answer:
a ≈ 8.7 units
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides , that is
a² + 5² = 10²
a² + 25 = 100 ( subtract 25 from both sides )
a² = 75 ( take square root of both sides )
a = 
≈ 8.7 ( to the nearest tenth )
The commutative property of multiplication states that the numbers can be multiplied in any order.
a+b = b+a : Commutative property of addition
a*b = b*a : Commutative property of multiplication
a+0=a : Additive identity property
a*1 =a : Multiplicative identity property
Answer : a*b =b*a
A quick sketch of the point in a coordinate grid reveals a 3x8 rectangle with a perimeter of 22. The distance between (-2,1) and (-2,4) is 3 and the distance between (-2, 1) and (6,1) is 8
Answer: x=3
Step-by-step explanation:
3x + 5 = 14
Subtract 5 from both sides
3x=9
Divide both sides by 3 to get x alone
x=3
