Answer: 20
Step-by-step explanation:
Assuming g(x) = -4x + 1,
( -4 (-4) + 1) - (-4 + 1)
= (16 + 1) - (-3)
= 17 + 3
= 20
Answer:
a = 145
b = 35
c = 145
d = 70
e = 70
f = 110
g = 55
h = 125
i = 55
j = 50
k = 70
l =110
m = 50
n = 60
o = 70
p = 23
q = 89
r = 68
s = 157
t = 112
u = 48
v = 132
w = 132
x = 48
y = 48
z = 132
A = 48
B = 94
C = 86
D = 94
E = 47
F = 133
Step-by-step explanation:
I'm fairly certain these are all correct... like 82% sure

BC is 10 units and AC is
units
Step-by-step explanation:
Let us revise the sine rule
In ΔABC:

- AB is opposite to ∠C
- BC is opposite to ∠A
- AC is opposite to ∠B
Let us use this rule to solve the problem
In ΔABC:
∵ m∠A = 45°
∵ m∠C = 30°
- The sum of measures of the interior angles of a triangle is 180°
∵ m∠A + m∠B + m∠C = 180
∴ 45 + m∠B + 30 = 180
- Add the like terms
∴ m∠B + 75 = 180
- Subtract 75 from both sides
∴ m∠B = 105°
∵ 
∵ AB = 
- Substitute AB and the 3 angles in the rule above
∴ 
- By using cross multiplication
∴ (BC) × sin(30) =
× sin(45)
∵ sin(30) = 0.5 and sin(45) = 
∴ 0.5 (BC) = 5
- Divide both sides by 0.5
∴ BC = 10 units
∵ 
- Substitute AB and the 3 angles in the rule above
∴ 
- By using cross multiplication
∴ (AC) × sin(30) =
× sin(105)
∵ sin(105) = 
∴ 0.5 (AC) = 
- Divide both sides by 0.5
∴ AC =
units
BC is 10 units and AC is
units
