Answer:
B: (4x - 7)(16x^2 + 28x + 49)
Step-by-step explanation:
64x^3-343 can be rewritten as 4^3x^3 - 7^3 or (4x)^3 - 7^3. This is the difference of two cubes. The appropriate formula for factoring such is
a^3 - b^3 = (a - b)(a^2 + ab + b^2). Therefore,
our (4x)^3 - 7^3 = (4x - 7)(16x^2 + 28x + 49). This is Answer B.
Answer:
Idk
Step-by-step explanation:
First you have to get the number on the right 40 to equal 100 so do 40x2=80- +40x1.5= 100
Then do the same thing to the first number 8 so 8x2=16+8x1.5=20
then you have 20/100 right so then that number over 100 is the percent that you get ^-^ 20%
