Step-by-step explanation:
let's look at the last line :
x³ + 8x - 3 = Ax³ +5Ax + Bx² + 5B + Cx + D
since we find A, B, C, and D by simply comparing the factors of the various terms in x (or constants) in both sides of the equation, we need to combine a few terms on the right hand side (so that we have one term per x exponent grade).
x³ + 8x - 3 = Ax³ + (5A + C)x + Bx² + (5B + D)
by comparing now both sides, to make both sides truly equal, the factors have to be equal.
A = 1 (the same as for x³ on the left hand side).
B = 0 (a we have no x² on the left side).
5A + C = 8 (a 8 is the factor of x in the left side).
5×1 + C = 8
5 + C = 8
C = 3
5B + D = -3 (as the constant term is -3 on the left side).
5×0 + D = -3
D = -3
so, the 4th answer option is correct.
Answer:
Probability would be 8/18 or 4.44%
Step-by-step explanation:
If its spun twice it acts as if it has 18 sections meaning you multiply the number of reds and number of squares total by two in this situation and put them over each other!
Because they react to iron and from rust
hope this helps
When you have powers of 10, the number is always 1 followed by how ever many zeros. So, in this case, 10 to the 4th power is 1 followed by 4 zeros, which is 10,000
(35/50)=(x/100)
35x100=3500
3500/50=70
so the answer is 70%
