X = -4
As g(x) is replaced by g(-4)
plug in -4 for x inside the equation.
g(-4) = (-4) - 1g(-4) = -5
Plug in -4 for x in f(x)f(-4) = 4(-4) - 4f(-4) = -16 - 4f(-4) = -20
Now solve for f(x) over g(x)
remember, f(x) = -20, and g(x) = -5
-20/-5 = 4
4 should be your answer

Its B just without the ^
A/4 + 2 = 6....subtract 2 from both sides
A/4 = 6 - 2
A/4 = 4...multiply both sides by 4, eliminating the 4 on the left side
A = 4 * 4
A = 16
-4 = r/20....multiply both sides by 20, eliminating the 20 on the right side
-4 * 20 = r
-80 = r
Answer:
A)58cm
B)
C)125.55square cm
Step-by-step explanation:
AB is a line is symmetry
Total length of left half part=12cm+9cm+3cm+5cm
Total length of left half part=29 cm
Length of left half part=Length of right half part
Therefore, length of right half part=29 cm
A) Perimeter of the shape=29cm+29cm=58cm
B)
Pythagoras theorem

Hypotenuse=12 cm
Base=5+3=8cm
In triangle ADC
Now, using Pythagoras theorem




C)
Area of shape=Area of triangle+ area of rectangle
Area of shape=
Where l=9cm
breadth=3+3=6cm
h=
base=2(5)+3(2)=16cm
Area of shape=
Area of shape=125.55 square cm
