Factor completely 4x2 − 8x − 60. (4x − 20)(x + 3) 4(x − 5)(x + 3) (4x − 4)(x + 15) 4(x − 1)(x + 15)

katovenus [111]

after complete factorization of $4x^2-8x-60$ the answer is $4(x+3)(x-5)$

Step-by-step explanation:

We need to factor $4x^2-8x-60$

Taking 4 common and factorizing:

$=4(x^2-2x-15)\\=4(x^2+3x-5x-15)\\=4(x(x+3)-5(x+3))\\=4(x+3)(x-5)$

So, after complete factorization of $4x^2-8x-60$ the answer is $4(x+3)(x-5)$

18 = 3 × 3 × 2

or (3 power 2 × 2)

10=2×5

a . GCF = 2

b. factor out 2 out of both 10 and 18 which their sum is 28 and write every thing that is left in the prantheses .

Plot the x-intercept(s), y-intercept, vertex, and axis of symmetry for the function below.

telo118 [61]

<span>g(x) = x^2 + 4x + 3

y-intercept: let x=0. Then y=3. y-intercept is (0,3).

roots: set g(x) = 0 and solve for x. x=-1 and x=-3.

-4
axis of symmetry: find x = -b / (2a), which here is x = ----- = -2

$P\approx0.90$

1) The first thing we need to do is to find the total number of visitors. This is going to be our Sample Space

31+26+2=31+28=59 Visitors altogether

2) The next thing to do is to find the favorable event. Note that we can see that 26 people purchased only one costume.

3) The final and last step is to find the probability, so we can write out the following:

$P=\frac{26}{59}=0.8965\approx0.90$

Thus, this is the answer: 0.90
