Answer:

Step-by-step explanation:
Given the rectangular poster shown in the picture, you know that its dimensions (its width and its lenght) are:

In order to calculate the dimensions of the rectangular at
times its current size, you need to multiply the original lenght by
and multiply the original width by
.
Knowing this, you get:

Slope of the line = (0- -5) / 6-3) = 5/3
in point slope form the equation is
y - 0 = 5/3( x - 6)
y = 5/3x - 10
multiply through by 3:-
3y = 5x - 30
In Standard form this is
5x - 3y = 30 Answer
In order to round to the nearest 100 you look at the 10s place.
It's 7 which means we round up. So 178 rounded to the nearest 100 is 200.<span />
Answer:
(ab - 6)(2ab + 5)
Step-by-step explanation:
Assuming you require the expression factorised.
2a²b² - 7ab - 30
Consider the factors of the product of the coefficient of the a²b² term and the constant term which sum to give the coefficient of the ab- term
product = 2 × - 30 = - 60 and sum = - 7
The factors are - 12 and + 5
Use these factors to split the ab- term
= 2a²b² - 12ab + 5ab - 30 ( factor the first/second and third/fourth terms )
= 2ab(ab - 6) + 5(ab - 6) ← factor out (ab - 6) from each term
= (ab - 6)(2ab + 5) ← in factored form
3/5 = .60, 65% = .65, 0.70 is the greatest
