Answer:

(x^2 + 3)(x + 1).

Step-by-step explanation:

x^3 + x^2 + 3x + 3

= x^2(x + 1) + 3(x + 1)

= (x^2 + 3)(x + 1).

SECOND TIME ASKINGAt a summertime poolside snack bar, 200 ice cream scoops were sold in one day. Double scoops were sold for $1.

Snezhnost [94]

What we know:

200 ice cream scoops sold in one day

$1 for Single scoop

$1.25 for Double scoop

Proceeds $221.75

What we want to know:

We want to account for Double scoops($1.25) and Single scoops($1) and end up with exactly 200 ice cream scoops. So if we have exactly 200 how many of each cone were sold.

Reference:

100 x $1= $100

100 x $1.25= $125

200 x $1= $200

200 x $1.25= 250

Work:

So using the reference above we can see that if you split 200 even we get $225 which is very close to $221.75.

So $225-$221.75= 3.25

If we have 117 and 83 we get 220.75 so how do we get that 1 dollar more. tax i guess....

A line passes through A(3,7) and B(-4,9) find the value of a if C (a 1) is on the line

Xelga [282]

What we need to do first, is to write the equation of the line through points A and B.

the slope of the line through A(3, 7) and B(-4, 9) is

$m= \frac{9-7}{-4-3}= \frac{2}{-7}=- \frac{2}{7}$

the equation of the line is :

$y-7=- \frac{2}{7}(x-3)\\\\y-7=- \frac{2}{7}x+ \frac{6}{7}\\\\y= - \frac{2}{7}x+ \frac{6}{7}+ \frac{49}{7}\\\\y= - \frac{2}{7}x+ \frac{55}{7}$

C(a, 1) is on this line so it must satisfy the equation:

$y= - \frac{2}{7}x+ \frac{55}{7} \\\\1= - \frac{2}{7}a+ \frac{55}{7}\\\\ \frac{2}{7}a= \frac{48}{7}\\\\2a=48\\\\a=24$
