1. Factor completely: 2a^2 + 6a + 18

USPshnik [31]

Answer:

$2(a+3)(a+3)$

$5(x+1)(x-1)$

$3t(t-2)(t+8)$

$n(2+n)(2-n)$

Step-by-step explanation:

Factor each expression

$2a^2 + 6a + 18$

$2(a^2 + 3a + 9)$

product =9 and sum =6

3 times 3 is 9

3 plus 3 is 6

$2(a+3)(a+3)$

2. Factor completely: 5x^2 − 5

GCF is 5

$5x^2 - 5$

$5(x^2 - 1)$

$5(x+1)(x-1)$

3. Factor completely: 3t^3 + 18t^2 − 48t

$3t^3 + 18t^2 -48t$

$3t(t^2 + 6t -16)$

product is -16 and sum is 6

-2 times 8 = -16

-2+8=6

$3t(t^2 + 6t -16)$

$3t(t-2)(t+8)$

4. Factor completely: 4n − n^3

$n(4 -n^2)$

$n(2+n)(2-n)$

Henry correctly factored 4x^(2)+5x-6 as (4x-3)(x+2). He then claimed that the zeros of that quadratic function are located at x=

svlad2 [7]

Answer:

I believe Henrey is wrong

Step-by-step explanation:

because the roots of the quadratic function are

<em>"</em><em>(</em><em>x</em><em>=</em><em> </em><em>3</em><em>/</em><em>4</em><em>,</em><em> </em><em>-</em><em>2</em><em>)</em><em>.</em><em>"</em>

Collins middle school's basketball team won 75% of their games if they lost the board games how many games did they win?

attashe74 [19]

<em>The phrase in the original question is:</em>

<em>....if they lost 12 games......</em>

<em>not</em>

<em>....if they lost board games......</em>

Answer:

36 games won

Step-by-step explanation:

Given

$\%Win = 75\%$

$Lost = 12\ games$

Required

Number of games won

Give that: $\%Win = 75\%$

The percentage loss is:

$\%Loss = 100\% - \%Win$

So, we have:

$\%Loss = 100\% - 75\%$

$\%Loss = 25\%$

Calculate the number of games (n) using:

$Lost = \%Loss * n$

$12 = 25\% * n$

Make n the subject

$n = \frac{12}{25\%}$

$n = 48$

So, the games won is:

$Win = n - Lost$

$Win = 48 - 12$

$Win = 36$
