6(10+z+3)
= (6)(10 + z +3)
= (6)(10) + (6)(x) + (6)(3)
= 60 + 6x + 18
= 6x + 78
Answer:
45
Step-by-step explanation:
KL = 12 because the triangle is isosceles ( base angles are congruent)
KJ = JM = 12 because the triangle is equilateral ( all angles are equal 60°)
the perimeter is
P = 9 + 12 + 12 +12 = 9 +36 = 45
In 12 days, Wendy will do the both again.
Step-by-step explanation:
Given,
Wendy goes to gym every 4 days
Wendy swims every 6 days
We will find the least common multiple of both the numbers in order to determine the number of days in which she will do both.
4 = 4,8,12,16,20,....
6 = 6,12,18,24,.....
Therefore;
The least common multiple of 4 and 6 is 12.
Thus,
In 12 days, Wendy will do the both again.
