Answer:
A
Step-by-step explanation:
Note that
x² + 12x + 36 is a perfect square → (x + 6)², hence
= = (x + 6)
Hence
f(x) × g(x)
= (x + 6)(x³ - 11)
= - 11x + 6x³ - 66
= + 6x³ - 11x - 66 → A
30% = 30/100
= 0.3
Now if we say that x% of a number is y then it actually means that x% multiplied by that number would be equal to y, thus:
30%*56 = 0.3*56
= 16.8
Answer:
∠ D = 35°
Step-by-step explanation:
∠ D is formed by a tangent and a secant and is one half the difference of the measure of the intercepted arcs, that is
∠ D = 0.5( arc EH - arc GE )
= 0.5(95 - 25)° = 0.5 × 70° = 35°
Answer:
Step-by-step explanation:
call the roots be a ,b
a + b = -13 / 5
