a wall is 100m long ,0.3 broad and 4.5m high .how many bricks of size 15cmlong 5cm width and 5cm thick are required to construct wall?​

no of brick=volume of wall/volume of brick=(10000×30×450)/((15×5×5)=135000000/375=360000.is your answer.

here

100m=10000cm

0.3m=30cm

4.5m=450cm

x^5/3y^1/3 the correct answer

hope it

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!
