The answer is: (2x+3) (3x+1)
Answer:
A. No
B. Yes
C. No
Step-by-step explanation:
Dimensions of each book are 4 inches by 11 by 14 inches.
A. Each book has a volume of 29 cubic inches.
Volume of each book = length × width × height
= 4 × 11 × 14
= 616 cubic inches
No
B. If the crate could hold 18 books the volume of the crate would be 11,088.
Volume of each book = 616 cubic inches
Volume of the crate = volume of each book × number of books
= 616 × 18
= 11,088 cubic inches
Yes
C. Each crate has a volume of about 8,524 cubic inches
If the crate holds 14 books,
Volume of the crate = volume of each book × number of books
= 616 × 14
= 8,624 cubic inches
No
Answer:
Step-by-step explanation:
the solution is right
x^2-6x-7=0:
x^2-6x-7=0
(add 7 to both sides)
x^2-6x=7
x^2-6x+9=7+9 (the coefficient of x² will be used to divide all sides)for here its 1, it will remain same ,
then we get the coefficient of x, divide it by 2 and square it and add it to both sides
which is like these
x²-6x=7
the coefficient of x is -6
-6/2 = -3, square it (-3)² = 9
then add 9 to both sides
x^2-6x+9=7+9
simplifiy the squares on the left hand side
x²+9 = (x-3)²
(x-3)^2=16
√(x-3)^2 )=±√16
x-3=± 4
x=-3±4
then simplify each sign
x=-3+4 x=-3-4
x=1 x=-7
Answer:
72,000
Step-by-step explanation:
20% of 60,000 = 12,000
60,000 + 12,000 = 72,000
Chow,...!
The product of p and 9 mean 9*p so 9p so the 3rd choice is right sure
