a)45min
b)900min
Step-by-step explanation:
We were told that it takes Matt 3 minutes to read one page in a book.
It implies that 3minutes = 1page of the book
Then he continues to read at the same pace, he can read 15 similar pages in minutes.
a)Then, he can read 15 similar pages in
15x3 minutes.which is 45minutes.
b)Then if the book has 300 pages, it will take him. 300×3 minutes to read it.which is 900mins
up to = less than or equal to
at least = greater than or equal to
The answer is correct
the max weight shall be 80
mass of small box = 5 lb. ( and there are x number of boxes )
Mass of big box = 12 lb. ( and there are y number of boxes )
adding them up shall be less than or equal to 80 ( as the shelf can withstand up to 80 lbs. )
And the minimum number of boxes shall be equal to 4
If we take the x as the number of boxes, then x would be greater than or equal to 4
Hope my answer helps!

Answer:
24x³-62x²+49x-12
Step-by-step explanation:
We can start by multiplying the first two brackets together first.
(3x-4)(2x-1)(4x-3) = (6x²-3x-8x+4)(4x-3)
Evaluate like terms.
(6x²-3x-8x+4)(4x-3) = (6x²-11x+4)(4x-3)
Multiply the two brackets together.
(6x²-11x+4)(4x-3) = 24x³-18x²-44x²+33x+16x-12
Simplify.
24x³-18x²-44x²+33x+16x-12 = 24x³-62x²+49x-12
Tell me if you need it in factorised form.
