b) x=36°
Step-by-step explanation:
Answer:
The rational numbers include all the integers, plus all fractions, or terminating decimals and repeating decimals. ... All natural numbers, whole numbers, and integers are rationals, but not all rational numbers are natural numbers, whole numbers, or integers.
Step-by-step explanation:
Answer:
Step-by-step explanation:
Always proceed by first extracting all common factors to all terms:
Notice that the factors: 5, x, and y are present in all terms, so we can extract them from the trinomial:
Now, the trinomial left (-x+2-3y) cannot be factored out, so then factoring is complete.
Answer:
Option 2
Step-by-step explanation:
In ΔABC,
AD is a median and point M is the point of concurrence of all medians.
Therefore, point M is a centroid of the triangle.
And M will divide line AD in the ratio of 1 : 2 (Ratio of AM : MD)
Since, length of MD = 2 cm
Therefore, length of AM = 4 cm
Total length of AD = AM + MD
= 2 + 4
= 6
Option 2 will be the answer.
