A. 6 + 6 = 12
b. 7 + 8 = 15
c. 0 + 0 = 0
d. 5 + -5 = -10
25:169 can be if is a rectangle ( times by the number itself )
or is is a square times by 2 ( 10/26)
The red line is a reflection across the x-axis, so the correct option is d.
<h3>
How to write the equation for the red line?</h3>
First, we know that the black line is represented by y = f(x). Here, we can see that the red line is given by a reflection around the x-axis.
This reflection only changes the sign of the right side, then we get that the function of the red line is:
g(x) = -f(x)
Then we can write this as:
y = g(x) = -f(x) = -1*f(x)
If we divide both sides by -1, we get:
y/(-1) = f(x)
Like in option d, so that is the correct one.

Answer:
21z+84
Step-by-step explanation.
7x3=21 then put the z at the end 21z.
7x12=84. Put it after the 21z. 21z+84
