The area of a 2D form is the amount of space within its perimeter. The total surface area of the square base pyramid is 297mm².
What is an area?The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm2, m2, and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.
The total surface area of the square pyramid is the sum of the area of the triangles and the area of the base. Therefore, the total surface area is equal to,
Total surface area = Area of square base + 4(Area of a triangular face)
= (9mm)² + 4(0.5×9×12)mm²
= 81mm² + 216mm²
= 297mm²
Hence, the total surface area of the square base pyramid is 297mm².

Jamaya is solving a riddle in order to find a mystery number. She knows the number is negative, and that the sum of 1/4 of the number and 2 is equal to the sum of 1/2 of the number and 4. What is the mystery number?
Answer:
x = -4
Step-by-step explanation:
let x equal the number
so
1/4(-x)+2=1/2(-x)+4
-1/4x + 2 = -1/2x + 4
+1/2x +1/2x
1/2x + 2 = 4
-2 -2
1/2x = 2
x = -4
Answer: x=-8
Step-by-step explanation:
1/4x+2=2x+16
Multiply by four to get rid of the fractions
X+8=2x+16
Combine like terms
-x=8
x=-8

Which is the best estimate of the following sum? 5 3/8 + 7 7/8 = ?

Step-by-step explanation:
First, solve 3/4 × 4 using repeated addition. Then, solve 4 × 3/4 using multiplication and division. Hint: The answer should be the same for both.
IN YOUR OWN WORDS PLEASE POINT AND BRAINLYST
Step-by-step explanation:
Repeated Addition:
3/4 +3/4 +3/4 +3/4 = 12/4 = 3
The denomenator will stay the same (4). So all you need to do is add the numerator (top. number in the fracton, 3)
It is the same logic as a basic multiplication problem using reapeted additon
(see example below:)
10 * 5 = 50
10 +10 +10 +10 +10 = 50
Multiplication:
4 * 3/4 = 12/4 = 3
You should not multiply the denomerator. You should only multiply the numerator. So you multiply 4 times 3 and get 12. So, you should get 12/4.

anyone know inverse operations, cause I am confused, I looked online and it said
Example: 20 + 9 = 29 can be reversed by 29 − 9 = 20 (back to where we started)
And the other way around:
Example: 15 − 3 = 12 can be reversed by 12 + 3 = 15 (back to where we started)
so like when do we do the 2nd way or can we just do either one of them???
Answer:
For inverse operations, it helps make solving equations easier. Say if you'd rather add than subtract, then you can do the inverse of a negative equation.
Inverse operations are also very helpful for linear equations.
To find the inverse of an equation, we change the plus sign to a negative sign. Then, we switch the first number and the answer.
Ex:
13 - 2 = 11 (now change plus to minus)
13 + 2 = 11 (not the answer yet)
Now we switch the first number with the answer!
11 + 2 = 13
Hope this helped, I tried to explain it easily.
