Example,
1). 2y(y³+4y²-9y)= I took 2y because it is GCF , just wrote something like (y³+4y²-9y)
to make second one i opened parentheses using distributive property
2y*y³+2y*4y²-2y*9y and then i got 2)
2). =2y⁴+8y³-18y²= to make 3) I took y² and made back distributive property
3). =y²(2y²+8y-18)=
4). = 2y²(y²+4y-9)=
5) =2y(y³+4y²)-18y²
all these equations are really equals to each other and to 2y⁴+8y³-18y², they are all the same, or equivalent

Answer:
£162.35.
Step-by-step explanation:
Total of letters + packages = 300.
Number of packages = 300 * 16 / ( 16+59)
= 300 * 16/75
= 64
So number of letters = 300 - 64 = 236.
No. of first class letters = 236 * 1/4 = 59.
No. of 2nd class letters = 236 - 59 = 177.
Total cost
= 64*1.2 + 0.52*59 + 0.31*177
= 162.35.
Answer:
<u>x = -6 and x = 1</u>
Step-by-step explanation:
For the fraction to be undefined, find the zeros of the polynomial of the denominator.
- x² + 5x - 6 = 0
- x² - x + 6x - 6 = 0
- x(x - 1) + 6(x - 1) = 0
- (x + 6)(x - 1) = 0
- <u>x = -6 and x = 1</u>
Answer:
B
Step-by-step explanation:
The answer is B because if you move two times to the right it gives you 0.09 like the eqution.
But scientific notation requires number without decimal, so the answer cannot be E because 0.9 is a decimal.
Just reminder: B and D have the same result!! just different coefficient
