Step-by-step explanation:
using Pythagoras a²+b²=c²
13²+16²
169+256=425
square root of 425 is 20.6 which round to 21 miles
(g + f)(x)
g(x) + f(x)
x - 1 + x^2 + 4
x^2 + x + 3
(g - h)(x)
g(x) - h(x)
3x + 1 - (2x - 2)
3x + 1 - 2x + 2
x + 3
Step 1: Multiply the number being expressed to 100
315: 420 • 100 = 75
Step 2: Multiply the expresser to 100
(315 • 100): 420 = 31500
Step 3: Divide the result by the number being expressed
31500/420 = 75
75 is the answer
Answer:
We start with this equation:
If x intercept is -4 then y = 0 giving us another point (-4, 0)
(4, -7) and (-4, 0)
slope = y difference / x difference = (-7 -0) / (4 --4) =
-7 / 8
