Q^2 - 125 = 0
q^2 = 125
q = +/- sqrt 125 = 11.18, -11.18
The answer is C. 55
You get your answer by adding together the degrees of the angles you know 55+70
That equals 125 degrees and subtract that from 180 degrees
180-125= 55
Lets say that the length of a rectangle is 12 cm and the width is 5 cm, you would add 12+12+5+5 (as in the length on both length sides and the width on both sides) so the perimeter of this rectangle is: 34 cm

Answer:
Mikayla moved the decimal incorrectly.
Step-by-step explanation:
mikayla evaluated the expression 0.86 × 23.4 using the steps shown below.
0.86
× 23.4
344
2580
+ 17200
= 201.24
LEts do the multiplication without decimals
8 6
x 2 3 4
--------------------
3 4 4
2 5 8 0
1 7 2 0 0
------------------------------
2 0 1 2 4
0.86 has two numbers after the decimal point and 23.4 has one number after the decimal point
So we move 3 places to the left ( 20.124)
Mikayla moved the decimal incorrectly.
