Answer:
-7
Step-by-step explanation:
To find the common difference, take the second term and subtract the first term
-2 - 5 = -7
Check by subtracting the second term from the third term
-9 - (-2) = -9+2 = -7
The common difference is -7
The two friends will be 150 miles apart, when the sum of the distances covered by the them is 150 miles.
distance = speed x time.
Let the time covered when they are 150 miles apart be x, then:
40x + 35x = 150
75x = 150
x = 150/75 = 2.
Therefore, the two friends will be 150 miles apart in 2 hours.
Answer:
SAS postulate
Step-by-step explanation:
In the figure attached, quadrilateral ABCD is shown.
The Side Angle Side (SAS) postulate states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then these two triangles are congruent.
AB is congruent to DC, and DB is the side common to triangles ABD and BCD. The included angle between sides AB and DB is angle ABD which is congruent with angle BDC, the angle included between sides DB and DC.
This is an exact answer. the answer will be a bit larger than 20
