Hi , we are going to begin with the numbers that are divisible with 2025 .
Basically I'm aware that 2 is not divisible , so we are going to use 3 .
2025 divided by 3 = 675 divided by 3 = 225 divided by 3 = 75 divided by 3 = 25 divided by 5 = 5
I used 5 because I cant use 3 , in other words you can divide 25 and 3 , but you will not get a whole number .I stopped when I divided 25 and 5 because I got 5 which is a [prime number] , when you are doing this type of exercises , when you see a prime number you have to stop.
So the prime factorization is 3 times 3 times 3 times 3 times 5 times 5.
Answer:
8x^3-7x^2-11x+9
Step-by-step explanation:
(8x^3-5x-1)-(7x^2+6x-10)
remove unnesasary ( )
8x^3-5x-1 -(7x^2+6x-10)
the distribute
8x^3-5x-1 -7x^2-6x+10
combine like terms
8x^3-11x+9-7x^2
use the communative property to reorder the equation
8x^3-7x^2-11x+9
Answer:
A piece of duct measures 48 inches.
In each connection, we lost 1 1/2 inches (i guess that it is what you wanted to write)
Then:
If we have 7 pieces of duct connected we have 5 connections (the ones in the extremes are not connected between them, so the number of connections is equal to the number of ducts minus two.)
So here we have 7 times 48 inches for the pieces, minus 5 times 1 1/2 in (i will write 1 1/2 = 1 + 0.5 = 1.5 in, so the math is easier) for the connections, the length is:
L = 7*48in - 5*1.5in = 328.5 inches.
for the 12 pieces duct, we have 12 pieces and 10 connections, so the length is:
L = 12*48in - 10*1.5in = 561 in
Now, if we want to make only one duct with those two, then we must add their lengths, but if we connect them, we also need to subtract the 1.5in of the new connection:
L = 561in + 328.5in - 1.5in = 888in
Answer:
1. d < 10
Step-by-step explanation:
Hi there !
8 > d - 2 | +2
8 + 2 > d - 2 + 2
10 > d
d < 10
Good luck !
