Answer:
D
Step-by-step explanation:
(f-g)(x) = f(x) - g(x)
=3x^3+8x^2-7x-4-(2x-6)
=3x^3+8x^2-9x+2
Answer:
3.15 ..........
Step-by-step explanation:
Answer:
see explanation
Step-by-step explanation:
(1)
CD = CE - DE = 8 - 2 = 6
CB = CD = 6 ( given as congruent ) , thus
AC = AB + CB = 4 + 6 = 10
(2)
∠ 2 + ∠ BCD + ∠ DCF = 180° ( sum of angles on a straight line )
∠ 2 + 60° + 70° = 180°
∠ 2 + 130° = 180° ( subtract 130° from both sides )
∠ 2 = 50°
Fractions are basically divisions.
Ex. 2/4 = 1/2
And whole numbers like 10, get greater when raised to an exponent.
Ex. 10^2 = 100
Answer:
True
Step-by-step explanation:
3:7 is girls to boys, and to find the total, do 7+3. After that, you'd get 10, and the ratio would be 3:10, so TRUE
