132 square units

Step-by-step explanation:

We are to find the surface area of a square pyramid.

From the diagram above, we are given:

Slant height = 6 units

Base = 8 units

The formula is given as:

= 2bs + b²

= 2 × 8 × 6 + 6²

= 96 + 36

= 132 square units

Answer:

1 Truncation

Truncation is a method of approximating numbers. It is easier than rounding, but does not always give the best approximation to the original number. Truncation is used in computing when division is done with integers and the answer must be an integer.

Please help 6×-5=7-9×

GrogVix [38]

Assuming ya mean 6x-5=7-9x

remmember, you can do anything to an equation as long as you do it to both sides

6x-5=7-9x
add 9x to both sides
6x+9x-5=7+9x-9x
15x-5=7+0
15x-5=7
add 5 to both sies
15x+5-5=7+5
15x+0=12
15x=12
divide both sides by 15
$x=\frac{12}{15}$
$x=\frac{4}{5}$

so $x=\frac{4}{5}$
