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:
2
Step-by-step explanation:
4/2 simply becomes a whole number. It can't be a mixed number.
Physical properties are used to observe and describe matter. Physical properties include: appearance, texture, color, odor, melting point, boiling point, density, solubility, polarity, and many others.
Answer: The distance is 17.
Step-by-step explanation:
Find their difference in the y values and the difference in the x values then find their absolute values.
2-17 = -15
-6 - 2 = -8
The absolute value of -15 is 15 and the absolute value of -8 is 8.
Now square them and add them up to find their square root.
15^2 + 8^2 = c^2
225 + 64 = c^2
289= c^2
c= 17
