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:
1:52
Step-by-step explanation:
The clock reads 1:45 so simply add 7 minutes to that
You need to multiply another number each time.
For Example:
3x2=6
6x3=18
18x4=72
72x5=360
360x6= 2,160
It's a pattern
How much were the power drills?
Answer:
$569.50
Step-by-step explanation:
15% deduction from the initial price(100%) will have us remaining with 85%
100% = 670
85% = <u>85% x 670</u>
100%
= $569.50
