Answer:
18 logs.
Step-by-step explanation:
Since a stove burns 4 logs per 2 hours, then the stove will burn 2 logs in one hour. There fore in 9 hours the stove will burn 2*9 which is 18 logs.
4:2= 2 logs per hour
2*9=18 logs per 9 hours.
Answer:
neither
Step-by-step explanation:
4x - 6y = -24 y = 2/3x + 4
-6y = -4x - 24
-6/-6y = -4/-6x -24/-6 y =2/3x + 4
y = 2/3x +4

5)
x = 132 - 42
x = 90
Answer
90 degrees, right angle
6)
180 - 126 = 54
The other two are congruent so 54/2 = 27
Answer
27
7)
An exterior angle of a triangle is equal to the sum of the opposite interior angles
So
6x = 38 + 82
6x = 120
x = 20
Answer
20
8)
Sum of interior in a triangle = 180 degrees
So
2x - 3 + 23 + 128 = 180
2x + 148 = 180
2x = 32
x = 16
Answer
16
Answer:
D 6
Step-by-step explanation:
note that (f ￮ g)(x) = f(g(x))
To evaluate f(g(x)) substitute x = g(x) into f(x)
f(g(x)) = f(4x³ + 1)
= 3(4x³ + 1)²
= 3(16
+ 8x³ + 1)
= 48 + 24x³ + 3 ← polynomial of degree 6
The degree of a polynomial is the value of the largest exponent, that is 6
