Answer:
Hence, Option 'C' is true.
Step-by-step explanation:
Given the expression
Apply distributive law: 
Here: 
so the expression becomes
∵ 
Therefore,
Hence, option 'C' is true.
Answer:
Step-by-step explanation:
10x^2(3x^2 - 5x) Remove the brackets (Distributive Property)
10*3*x^2 * x^2 - 5x * 10x^2
30 x^(2 + 2) - 5*10x^(2+1)
30x^4 - 50x^3
Answer:
A= .75 B= .75
Step-by-step explanation:
Plug in .75. 5(.75) + 3(.75) = 6
7(.75) + 9(.75) = 12
You would turn a to x and b to y to get ---> 5x + 3y = 6 and 7x + 9y = 12 -----> then you would multiply the first equation ^^^^^ by 3 to cancel to give you 15x + 9y = 18 (I did that to get 9y and cancel out the 9y in the other equation) next do 15x + 9y = 18 - 7x + 9y = 12 to get ----> 8x = 6 ---> divide by 8 to get ---> x = .75
Hope this helped!!
If they want you to find the perimeter I guess you add all sides so 9+9+9+9+30 = 66
