Answer:
149.45 cm²
Step-by-step explanation:
Surface area of pyramid = ½Pl + BA
Perimeter of the base (P) = 7 + 7 + 7 = 21 cm
Slant height (l) = 12.2 cm
Area of base (BA) = ½*bh = ½*7*6.1 = 21.35 cm²
Plug in the values
Surface area = ½*21*12.2 + 21.35 = 149.45 cm²
Hello there!
The additive inverse of any number just means to flip it's value.
For example;
The number "3" would have an additive inverse of "-3".
The number "-15" would have an additive inverse of "15".
Since we have "52", we can flip the value sign of it.
We now have -52 and 52.
Since the question asked us to sum our numbers, we need to add them.
-52 + 52 = 0
The sum of 52 and its additive inverse is 0.
I hope this helps!

Because the pattern so far has gone blue, red, blue so the next one must be red.
And the section numbers are increasing by one each time. 1, 2, 3 so the next one must be 4.
