Answer:
S.A=132
Step-by-step explanation:
A=[ x b x h]2
A= x 4 x 3 x 2 12+50+40+30=132
A=12 cm²
A=L x W
A=10 x 5=50
A=L X W
A=10 X 4=40
A=L X W
A=10 X 3=30
Answer:The left side 13 is greater than right side -3.6 which means statement is true
Weight of copper = 1/2w and weight of zinc = 1/2 w
So:-
c = 0.5w*6 + 0.5w*3
c = 3w + 1.5w = 4.5w
this equation is the same as choice A
For this just simply substitute the values with the corresponding variable.
10(-2)-4(1)
-20-4
-24 is your answer for the expression
