Answer:
85
Step-by-step explanation:
Opposite angels are congruent (D = B). Consecutive angles are supplementary (A + D = 180°)
My answer would be 14 miles. I really hope this is what you need
Answer:
Kameron is 50 years old.
Step-by-step explanation:
We can make equations and start filling in what we already know, assuming
is Niko's age,
is Lila's age,
is Amber's age, and
is Kamerons age.
Our first equation:
n = 3L
We know that Niko is 45, so
45 = 3L
Divide both sides by 3:
L = 15
So, Lila is 15 years old.
Another equation:
n = L + 3a
We already know Niko and Lila's age:
45 = 15 + 3a
Subtract 15 from both sides:
30 = 3a
Divide both sides by 3:
a = 10
So Amber is 10 years old.
Another equation:
k = 2(a + L)
We know Amber and Lila's age:
k = 2(10 + 15)
k = 2(25)
k = 50
So Kameron is 50 years old.
Hope this helped!
A polynomial is every function that looks like this:
f(x)=(An)*xⁿ + (An-1)*xⁿ⁻¹ +.....+A₁*x +A₀
So functions that are polynomials are:
3x²-5x⁴+2x-12,
x⁵-5x⁴+4x³-3x²+2x-1,
x⁻⁵-5x⁻⁴+4x⁻³-3x⁻²-1,
x³-7x²+9x-5x⁴-20.
And functions that are NOT polynomials:
4/x⁴ + 3/x³ - 2/x² -1,
⁴√x - ³√x + ⁴√x - 8x +16.
So the second picture is correct.
