Factor the perfect-square trinomial in y = (x2 + 2x + 1) − 1− 1.<br> y = (x + <br> )2 − 1 −1

$y = ( {x}^{2} + 2x + 1) - 1$

$y = ({x + 1})^{2} - 1$

$y = ({x + 1})^{2} - ({1})^{2}$

We're done now but I have something to tell...

Hint :

${a}^{2} - {b}^{2} = (a + b)(a - b)$

$y = ( \: (x + 1) + 1)( \: (x + 1) - 1) \\$

$y = (x + 2)(x)$

In the first game of the year, the modified basketball team made 63.5% of their foul shot free throws. Matthew made all 6 of his

SVETLANKA909090 [29]

So 6 shots equal 25% of the teams total shots(x)
So 6= 0.24(x)
X = 6/0.25
X= 24

If the team made 62. 5% of their shots then they missed 100% - 6.25% = 37.5 %
37.5 % of 24 = 24(0.375) = 9

How to use the distributive property to write an expression equivalent to 5x(3 4)?

Nitella [24]

I am assuming theres an addition sign between the 3 and 4.
So basically you want to multiply the 5x by both terms so it will end up being
(5x•3) + (5x•4)
Now simplify:
15x+20x
Hope this helped ^_^
