First, you have to set up an equation using the formula for area of a rectangle:
L x W = H. Then, plug in what you know: 8 x W = 56. Then, solve for x by dividing 56 by 8: W=7.
Answer:
C. 8a - 36
Step-by-step explanation:
a + 3a - 4(9-a)
a + 3a - 36 + 4a
8a - 36
Answer:
D. (7^2 X2) x 4
The equation inside the parenthesis finds the volume of one pan and then that is multiplied by 4 which is the total number of pans. This will find the volume of all 4 pans.
Answer:There are 4200 bacteria in a lab dish. The population decreases 8%per day. How many bacteria are there after day 1? Round to nearest whole number
Step-by-step explanation:
believe what you're asking is to turn the trinomial into two binomials
So you first have to get 3x²; the only way to get this is
(3x )(x ) when multiplying that, you would get 3x²
when dealing with the -8x and the 4, you must find numbers that are factors of four (when multiplied together they will equal 4) and will multiply with the x's to get -8
(3x-2)(x-2)
you can tell that this is the answer because when you multiply though you will get:
3x-2x²-6x+4
or: 3x²-8x_4
Hope this helped
