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:
i think it would be B because if AC= 80 and thats like the distane between then abc would be 80 if im thinking right
Step-by-step explanation:
but hey if im wrong ill have my friend punch me in the arm to make it even
Certain means the event will happen.
Impossible means the event would never happen.
125/1000 because half of 0.5 is 0.25 and half of 0.25 is 0.125 and 0.125 is 125/1000
The S in supplementary<span> can be used to form the 8 in 180. The C in </span>complementary <span>can be used to form the 9 in 90. If we know that a set of </span>angles<span> form one of these special relationships, we can determine the measure of the other </span>angle<span>. To determine the supplement, subtract the given </span>angle<span> from 180.</span>
