Answer:
1. distributive
2. associative
Step-by-step explanation:
In the first one, they are distributing 16 + 23 by the 4.
Therefore it is distributive property as they are splitting and then separately multiplying.
In the second one, the parentheses are shifted. The shifting of parentheses indicates priority, and the associative property says in addition you can choose what you'd like to do first and it won't change the answer.
I believe the answer is C. q = -9.
You can think of a square as two isosceles right angle triangles and use Pythagoras.
x^2 + x^2 = 22^2
x^2 + x^2 = 484
2x^2 = 484
x^2 = 242
x = 11√2
One side of the playground is 11√2 m long.
Answer:
40 degrees, 60 degrees, and 80 degrees
Step-by-step explanation:
2+3+4=9
180/9=20
20*2= 40
20*3 = 60 and
20*4=80
Multiply the number by 100, making this one 115%
