Answer:
Add
Step-by-step explanation:
10.65*40=426
426+50=476
a
because you get more than you do in choice b
Answer: 26
124 + 30 = 154
180 - 154 = 26
y+z=10
x+z=8
x+y=12
(y+z)-(x+z)=10-8
y-x=2
y+x=12
solve simultaneously
x=5, y=7
then substitute to get z=3
hence xyz=573
area of square =length × length ×height
=6×6×8
=288
