1. Measure and angle in degree
Answer:
angle A + angle B = 180 degrees is correct
Step-by-step explanation:
16/155 = n
explanation
A linear equation is an equation of a straight line. To solve linear equations, it is important to keep the following key concepts in mind:
Maintain balance of the equation by applying the same operations to both sides of an equation
Isolate for the variable by collecting like terms
Use inverse operations to rearrange an equation
to show your work
-8/ 5 = -31/2 • n
- 8/5 = -31n/2
2(-8/5) = 2 • -31/n
-16/5 = -31n
-16/5 / -31 = -31n/31
16/155 = n
Answer: 1.79
Step-by-step explanation: x2−6x−14=0
For this equation: a=1, b=-6, c=-14
1x2+−6x+−14=0
Step 1: Use quadratic formula with a=1, b=-6, c=-14.
x=
−b±√b2−4ac
2a
x=
−(−6)±√(−6)2−4(1)(−14)
2(1)
x=
6±√92
2
x=3+√23 or x=3−√23
Answer:
x=3+√23 or x=3−√23= 1.79
