If you would like to find the number which belongs in the blank to complete the square, you can calculate this using the following steps:

f(x) = 5(x^2 - 4x + a) + 15
a ... the number = ?

<span>x^2 - 4x + a = (x - 2)^2 = x^2 - 4x + 4
</span>a = 4

The correct result would be 4.

Can you help me get the answer I’m just not sure if I’m right

zhenek [66]

Answer:

430 $in^{2}$

Step-by-step explanation:

To find the area, use the area for a parallelogram formula:

A = bh, where A is the area, b is the length of the base, and c is the height of the parallelogram.

Next, substitute the values of the base and height:

A = 20in. * 21.5 in.

Finally, simplify the multiplication:

A = 430 $in^{2}$

How many cubes with side lengths of 1/3 does it take to fill the prism?

Ugo [173]

Answer:

180 cubes

Step-by-step explanation:

little cubes:

$v=(\frac{1}{3} )^{3} =\frac{1}{27}$

The prism:

$v=(\frac{5}{3})(\frac{4}{3} )(2)=\frac{40}{9} =\frac{20}{3}$

the number of cubes that fill the prism:

$cubes=\frac{\frac{20}{3} }{\frac{1}{27} } =\frac{(20)(27)}{(3)(1)}= \frac{540}{3} =180$

Hope this helps
