Answer: A)x²+x-6 B) 2x²-13
Step-by-step explanation: A) (x+3)(x-2)(x-8) = x²-2x+3x-6 = x²+x-6
B) (x+2)(x-2)(x+3)(x-3) =→ x²-2x+2x-4 = x²-4
→x²-3x+3x-9 = x²-9
∴x²-4+x²-9 = <u><em>2x²-13</em></u>
Sums of cubes can be factored as
So
Answer:
16 to 4
Step-by-step explanation:
8 to 2 can be reduced to 4, so to have a ratio equivalent, it must be able to be reduced to 4 also. An example would include, 16 to 4.
Answer:
47.1 inches
Step-by-step explanation:
The formula for finding circumference is C = D x pi
So, we go 15 x 3.14, and we get 47.1 inches
The expected value of the inseam length of the jeans is found as
30% of 30+ 25% of 32+ 10% of 34+ 10% of 36 + 10% of 38 + 15% of 40
= 
= 
Hence, the third option 33.8 is the correct expected value.
