Answer:
m = - 8 ± 6
Step-by-step explanation:
Given
m² + 16m - 8 = 0 ( add 8 to both sides )
m² + 16m = 8
To complete the square
add ( half the coefficient of the m- term )² to both sides
m² + 2(8)m + 64 = 8 + 64
(m + 8)² = 72 ( take the square root of both sides )
m + 8 = ± 
= ± 
= ± 6
Subtract 8 from both sides
m = - 8 ± 6
Answer:
18km/[unit of time]
Step-by-step explanation:
v (speed) = d/t
v = 198/11
v = 18
YZ = 16. The triangles are congruent. This would be AAS so YZ = 16 because of CPCTC.
Based on the information given, it can be noted that RUTS is a rectangle because the opposite sides are parallel and have equal lengths.
<h3>
Proving the rectangles.</h3>
RU = ST, UT = RS because the opposite sides are parallel and have equal length.
STU and SRU are right angles because they've 90°. Also, URS will be equal to STU. Lastly, USR = SUT because the angles are both alternate angles.
