Answer: 100
Step-by-step explanation:
Sub in 5 for b in the expression

You must do the exponent first as it comes before multiplication in the order of operations

Now multiply


Actually Welcome to the Concept of the Triangles.
Since there is a linear pair with 40° , the another angle will be 140° ,
also the triangle newly formed is a isosceles one,
hence x = 20°
===> x = 20°
Now apply angle sum property of a triangle on, the other one,
we get as, 70+40+y=180
hence, y = 180-110
y = 70°
Hence angle y ==> 70°
Answer:
y= -2x - 1
Step-by-step explanation:
that is the answer sorry if wrong
Answer:
-23
Step-by-step explanation:
Each term is 6 less than the past term. Hopw this helps!
A=bh
divide by 'b' to isolate 'h'
A/b=h
