Factor z2 + 17z + 72.

Nadya [2.5K]

Hello!

It looks like you meant,
$z^2+17z+72$
Break the expression into two groups, that would imply splitting the 17.
$=\left(z^2+8z\right)+\left(9z+72\right)$
Let's start factoring.
First, factor the $z$ from $z^2+8z$
Then, factor the $9$ from $9z+72$
We would be left with,
$=z\left(z+8\right)+9\left(z+8\right)$
Factor out the common term, which is $(z+8)$
$=\left(z+8\right)\left(z+9\right)$

Our final answer would be,
$=\left(z+8\right)\left(z+9\right)$

How many miles is 1000 feet?

shtirl [24]

1000 miles would be 5,280,000 feet.

If one mile is 5,280 feet, multiplying this by 1000 will give you the distance of 1000 miles. You can also do it quickly by adding the zeroes (in the case of 1000 there are 3) to 52800 to indicate multiplication by three places.

Which formulas can be used to find the surface area of a right prism where p is the perimeter of the base, h is the height of th

svp [43]

Let
ba--------> area of bases (the two bases included)
p---------> perimeter of the base
h--------> height of the prism
la-------> lateral area

we know that

[surface area]=2*[area of one base]+[perimeter of the base]*height
so
2*[area of one base]=ba
[surface area]=[ba]+[p]*h

and
the formula of lateral area is
[la]=[perimeter of the base]*height
[la]=[p]*h
therefore
[surface area]=[ba]+[la]

the answer is
[surface area]=[ba]+[p]*h
[surface area]=[ba]+[la]
