Answer:
440
Step-by-step explanation:
Her we have two objects: 2 square.
1st has dimension 5x5x8
2nd has dimension 10x10x2
But we also have invisible prarts, the bottom of 1st is on the top od the 2nd. So we will remove something.
The formula for the surface of the square is
S=2B+M
Surface area of the first is
S1=2x5x5+4x8x5=50+160=210
Surface are of the 2nd is
S2=2x10x10+4x10x2=200+80=280
S=s1+s2-50=210+280-50=440
This -50 is are od one base from first square 5x5=25 whic we added in s1, but in real it is invisible.
The same area we added in s2. The top is 10x10-5x5 (invisible prat).
So we added two times 25, it is 50.

tell me the method to solve i think u have done this before or not
Answer:
4
Step-by-step explanation:
divide by 2 and you will have your answer
-x = 2 - 3x + 6
Add 3x to both sides.
-x + 3x = 2 + 6
Simplify.
2x = 8
Divide both sides by 2.
x = 4

Answer:
the desire expression is 19multiply(3 tens)=19multiply30=570
Step-by-step explanation:
19 ✖️ 1ten=19 ✖️ 10=190
19 ✖️2tens=19 ✖️ 20=380
19 ✖️ 3tens=19 ✖️ 30=570
19 ✖️ 4tens=19 ✖️ 40=760
but here 760 is over the given terms 684,but 570 is the nearest value to the value 684
so the desire expression is 19 ✖️ 3tens=19 ✖️ 30=570
