-7p + -7p^2 + -6(-3p^2 + -10) How do you simplify this?

1 answer:

5 0

SIMPLIFY:
−7p+7p^2+6(−3p^2+ −10)

DISTRIBUTE:
= -7p+-7p^2+(-6)(-3p^2)+(-6)(-10)

= -7p+ -7p^2+18p^2+60

COMBINE LIKE TERMS:
= -7p+ -7p^2+18p^2+60

= (-7p^2+ 18p^2)+(-7p)+(60)

ANSWER:
= 11p^2 - 7p + 60

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

user100 [1]

Answer:

The number of cubes that fill the prism is 24

Step-by-step explanation:

Given as :

The length of cube (l) = $\frac{1}{3}$ cm

The length of prism (L) = 1 cm

The width of prism (w) = 2 $\frac{2}{3}$ = $\frac{8}{3}$ cm

The height of prism (h) = $\frac{2}{3}$ cm

Let the number of cubes that fill the prism = x

Now, Volume of cube with length (l) = l³ cm³

Or, Volume of cube with length (l) = $(\frac{1}{3})^{3}$ cm³

Or, Volume of cube with length (l) = $(\frac{1}{27})$ cm³

Again , Volume of prism = $\frac{1}{2}\times Length \times width \times height$

Or, Volume of prism = $\frac{1}{2}\times 1 \times \frac{8}{3} \times \frac{2}{3}$

Or, Volume of prism = $(\frac{8}{9})$ cm³

<u>So , The number of cubes to fill prism </u>

The number of cubes × Volume of cube = Volume of prism

Or, x × $(\frac{1}{27})$ cm³ = $(\frac{8}{9})$ cm³

or x = $\frac{8\times 27}{9}$ = 24

Hence The number of cubes which fill the prism is 24 Answer

Find the greatest common divisor (GCD) of 34255 and 203515.

seropon [69]

34255 = 5 * 13 * 17 * 31
203515 = 5 * 13 * 31 * 101

So GCD(34255, 203515) = 5 * 13 * 31 = 2015
