Answer:
4x^2 +9x/4 -7
Step-by-step explanation:
f(x) =x/4 - 3
g(x) = 4x^2 + 2x - 4
(f +g)(x) = x/4 - 3 + 4x^2 + 2x - 4
= 4x^2 + 8x/4+x/4 -7
= 4x^2 +9x/4 -7
⇒ s = a+b+c2=5+12+132 a + b + c 2 = 5 + 12 + 13 2 = 15 cm.
Area of the base = √s(s−a)(s−b)(s−c)
= √15×10×3×2 15 × 10 × 3 × 2 cm2 = 30 cm2

Answer:
0.16km
Step-by-step explanation:
Unless I am missing something it is a simple subtraction problem and the time is not needed. It is simply asking how much farther Avery ran than Max, which is 1.61km - 1.45km which is 0.16km
Answer:

Step-by-step explanation:
"5 or above, give it shove. 4 or below, let it go." The number is the tenth's place is 2(since this isn't a decimal), and you need to round it by the number to it's right: which is 8. Since 8 is greater than 5, you change the 2 to a 3 and the 8 becomes a 0.
