Answer:
x = 29°
Step-by-step explanation:
The angle measures tell you the triangles are similar, so corresponding sides will have the same ratio.
GX/BX = UH/NH
GX = BX·UH/NH
GX = 7·18/(3√11)
GX = (42/11)√11
GB/BX = UN/NH
GB = BX·UN/NH
GB = 7·15/(3√11)
GB = (35/11)√11
Since 8 is above 5 it will round the 19 up to a 20 and everything behind turn into a 0
Answer: -3
Step-by-step explanation:
The average rate of change is 
. All we have to do is to plug in our values.
a=-2
b=-1
f(b)=f(-1)=(-1)²+10=11
f(a)=f(-2)=(-2)²+10=14
With our values listed, all he have to do is to plug them in.
The answer is (B) commutative property of addition.
