Answer:
3xz5+2x+4y−2z
Step-by-step explanation:
2x−5y+3z5x+9y−2z
=2x+−5y+3xz5+9y+−2z
Combine Like Terms:
=2x+−5y+3xz5+9y+−2z
=(3xz5)+(2x)+(−5y+9y)+(−2z)
=3xz5+2x+4y+−2z
Answer:
15
Step-by-step explanation:
65×252=?
For fraction multiplication, multiply the numerators and then multiply the denominators to get
6×255×2=15010
Since 150 divided by 10 equals 15 then,
15010=15
Therefore:
65×252=15
The area of a rectangle is base * altitude, and the perimeter is 2*base + 2*altitude,
base = 10cm and altitude = 7cm
