Answer:
210 seconds
Step-by-step explanation:
LCM of 5,6 and 7
Answer:
5
Step-by-step explanation:
if xz is 15 and xy is 10 then we can infer that z is 10 and x is 5
There are 6 squares so u multiply 6x3=18 is the total surface area
You multiply a number by 3 subtract 6 then add 2 the results is 20
what's the number ?
Let the number = x
multiply a number by 3
so, it becomes 3x
subtract 6 , so, 3x - 6
then add 2
so, 3x - 6 + 2
The result will be 20
So,
3x - 6 + 2 = 20
solve for x
3x - 4 = 20
Add 4 to both sides
3x - 4 + 4 = 20 + 4
3x = 24
Divide both sides by 3
3x/3 = 24/3
So,
x = 8
D. (xy2 + 3z14)(x2y4 – 3xy2z14 + 9z28
