Step-by-step explanation:
The sum of the first 9 consecutive odd numbers is
1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17 = 81
Answer:
There are three terms in the simplified expression.
Step-by-step explanation:
We have to simplify the expression and have to count the number of terms that the expression has.
The expression is 4y - 6 + y² - 9
= 4y + y² - 6 - 9
= y² + 4y - 15
Therefore, there are three terms in the simplified expression, one for y² term, another is y term and the constant term. (Answer)
Answer:

Step-by-step explanation:
t = 7m
Let m = 6
t = 7*6 = 42
Let m = 8
t = 7*8
t = 56
Answer:
Step-by-step explanation:
remember that,
<u>if a side of a triangle is extended then exterior angle so formed equal to the sum of the two opposite interior </u><u>angles</u>
thus our equation is
cancel out 86° from both sides:
hence,
the measure of the missing angle is 49°
Answer:
5hours
Step-by-step explanation:
At constant speed, distance speed= distance/time taken
therefore, time will be obtained by the division of distance traveled by the speed.
in this question the distance is provided but time is not hence time is calculated as follows. time= distance/time taken
=275miles/55miles/hour
= 5hours
