The first step would be the square of the parenthesis.
-5x²(4x∧6-x∧4)
4x∧6 means 4x to the sixth power.
I hope that helps.
Answer:
Hello! 59.2 is our answer
This is because for all the triangles we do 5.4 x 4 = 21.6 then I divide by 2 cause thats the formula when doing triangles so I get 10.8 and sense all the triangle sides our the same I do 10.8 x 4 and get 43.2 then for the bottom side I just have to do 4 x 4 cause thats the formula and get 16 then I add these up so 43.2 + 16 = 59.2 and We get our answer 59.2 Hope this helps!
Answer:
33.75
Step-by-step explanation:
Given that the manufacturer produces an average of 450 televisions each day and 0.25% of the numbers produced each day are defective.
Therefore
0.25% of 450 will give the number of defective televisions produced per day
So
0.25% /100 x 450
0.0025 x 450
1.125
This means that 1.125 of televisions produced each day are defective.
Now to get the estimate of defective televisions in 30 days , multiply the number of defective televisions per day by 30 days seeing that the producer produces an average of 450 each day
So
1.125 x 30
33.75
33.75 televisions are defective in 30 days
Find common denominator
5 x 4 = 20
2 x 4 = 8
2 x 5 = 10
8/20 + 10/20 = 18/20
18/20, or 9/10 simplified, is your answer
Hope this helps
