Answer:

Step-by-step explanation:
when you raise an exponent to a power you multiply
Also since the terms inside the parenthesis are multiplied and not added, you don't have to worry about expanding it

Answer:
You can fill 13.5 pages
Step-by-step explanation:
You would do 54 divided by 4 equals 13.5
The diameter is 49
you take 153.86 and divide it by 3.14
Answer:
The measure of angle N is 55°
Step-by-step explanation:
we know that
the law of cosines established
a² = b² + c² – 2*b*c*cos(A)
so
In this problem we have
a=ML=5.74 units
b=LN=4 units
c=MN=7 units
∠A=∠N=?
see the attached figure to better understand the problem
a² = b² + c² – 2*b*c*cos(A)------> cos (A)=[b²+c²-a²]/[2*b*c]
cos (A)=[4²+7²-5.74²]/[2*4*7]------> 0.57236
A=arc cos (0.57236)--------> A= 55°
therefore
The measure of angle N is 55°
Answer:
A & C
Step-by-step explanation:
for A - and + is always -
so 2.3-2.3 =0
for C - and - is always + so
-2.6--124 = -2.6+124
=121.4 which is positive
