Answer:

Step-by-step explanation:

2ax -6ay +bx -3by

take common from first two terms and take common from third and fourth term

=2a(x-3y)+b(x-3y)

take common (x-3y) is common

=(x-3y)(2a*1+b*1)

=(x-3y)(2a+b)

Answer:

The answer is

$\frac{2s}{n} - l = a$

Step-by-step explanation:

$s = \frac{n}{2} (a + l)$

multiply both sides by 2 to get

$2s = n(a + l)$

divide both sides by n to get

$\frac{2s}{n} = a + l$

subtract L from both sides to get the answer

$\frac{2s}{n} - l = a$

What percent of 20 is 15

Vesnalui [34]

To solve for this, we need to set up fractional proportions.
We have x% out of 100%, x being what we're looking for and 100 being the total maximum percent.
We have 15 out of 20, being one of our fractions.
Our fractions are:
x/100 = 15/20.
To solve for this, we need to cross multiply the denominator of one fraction by the numerator of the other fraction.
Multiply x and 20, and then 100 and 15.
You should end up with:
20x = 1500.
Divide both sides by 20 to solve for x.
20x/20 = x.
1500/20 = 75.
x = 75.
Your final and absolute answer is :
15 is 75% of 20.

Take a look at the figure. The distance h a body will move in free fall is expressed by the formula shown. If g = 980 centimeter

matrenka [14]

I'm not sure what D says but if it is 196000 cm then that is the answer.
