Answer:
x = 12/5
Step-by-step explanation:
take the square of both sides
(x^2+49) = (x+5)^2
x^2 + 49 = (x+5) (x+5)
x^2+49= x^2 + 10x + 25
10x + 25 = 49
10x = 24
x = 12/5
67 + 23 = 90
Because this pair of angles adds up to 90, they are complementary angles.
Hope this helps!! :)

Answer:
see below
Step-by-step explanation:
(2 · x) · 6 = 2 · (x · 6) → Associative property of multiplication, this property states that (a · b) · c = a · (b · c), basically, it doesn't matter what order you multiply in, the result will always be the same.
3(3x + 2) = 9x + 6 → Distributive Property, this property states that a(b + c) = a · b + a · c.
(7 + 1) + 5 = 5 + (7 + 1) → Commutative property of addition, this property states that a + b = b + a which means that you can "flip" or "switch the positions of" the quantities being added and you will still get the same result.
(7 · x · 3) = (7 · 3 · x) → Commutative property of multiplication, just like the commutative property of addition, this states a · b = b · a, in other words, you can "flip" or "switch the positions of" the quantities being multiplied and you will get the same result.
(9 + 2) + 3 = 9 + (2 + 3) → Associative property of addition, just like the associative property of multiplication, this property states that (a + b) + c = a + (b + c), in other words, it does not matter which order you add in, the result will always be the same.
