The pack of pencils weighs 21.6 grams because 0.9 times 24 is 21.6

I'm pretty sure you just do 24 x 0.9 which is 21.6

so they weigh 21.6 grams

Which binomial is a factor of w^2-w-20

Lubov Fominskaja [6]

Answer:

From the given options, option D is the only choice that contains (w-5).

Step-by-step explanation:

Given the expression

$w^2-w-20$

Breaking the expression into groups

$=\left(w^2+4w\right)+\left(-5w-20\right)$

Factor out 'w' form w²+4w = w(w+4)

Factor out 'w' from -5w-20= -5(w+4)

$=w\left(w+4\right)-5\left(w+4\right)$

Factor out common term: w+4

$=\left(w+4\right)\left(w-5\right)$

Thus, the factors are: (w+4) and (w-5)

Therefore, from the given options, option D is the only choice that contains (w-5).

The areas of two equilateral triangles are 27 yd2 and 75 yd2. Find the ratio of their perimeters.

Cloud [144]

If the areas of two equilateral triangles are 27 yd² and 75 yd², then the ratio of these areas is 27/75 = 9/25

If the ratios of the areas are 9:25, then their similarity ratio and the ratio of their perimeters is √9:√35 = 3:5.
