(2y-9x)²
(2y-9)(2y-9)
the equation is ² so break it
into two bracket

4y²-18y -18y+81 multiply it out
=4y² - 36y + 81 (the answer)

The ratio of red cars to blue cars in a parking lot was 5:3 . If there was 40 red cars , how many blue cars were there ?
Bas_tet [7]
The answer is x equals 24
you set up a proportion new over old
so for red cars 40 over 5
since we don’t know the new for blue cars we’ll use x
so x over 3
we then make them equal to each other
40 x
—- = —-
5 3
cross multiply, then we get
120=5x
isolate the x by dividing 5 from both sides to get 24

Split the second term in 5x^2 + 23x + 26 into two terms

5x^2 + 13x + 10x + 26

Factor out common terms in the first two terms, then in the last two terms

x(5x + 13) + 2(5x + 13)

Factor out the common term; 5x + 13

<u>(5x + 13)(x + 2)</u>
