PLEASE HELP MEEE
Romashka-Z-Leto [24]

Answer:

2x^3 + 9x^2 + 16x + 21.

Step-by-step explanation:

We first multiply the expression in the second parentheses by x , then by +3:

(x + 3)(2x^2 + 3x + 7)

= x(2x^2 + 3x + 7) + 3(2x^2 + 3x + 7)

= 2x^3 + 3x^2 + 7x + 6x^2 + 9x + 21   Now we add like terms:

= 2x^3 + 9x^2 + 16x + 21.

Nerissa paid a total of $8 for 4 packs of pencils she purchased from the convenience store. Let p represent the cost of one pack
BARSIC [14]

Answer: 4*p=8

Step-by-step explanation:

<em>You can use inverse operation to answer this equation.</em>

  • <em>write out you problem: 4 x p =8</em>
  • <em>The inverse of multiplication is division</em>
  • <em>you do 4/4 which gives you one but the 4 will cancel itself out</em>
  • <em>Do 8/4 which gives you 2</em>
  • <em>under the equation write p = 2</em>
  • <em>And be sure to line the p up with the p, the equal sign with the equal sign, and  the 2  stays where it is ( which should be already lined up with the 8)</em>

Write the equation of the line in point-slope form that passes through (5, -1) and has a slope of 2/3
kolezko [41]

Answer:

y-(-1)=2/3(x-5)

Step-by-step explanation:

Point slope form is

y-y_1=m(x-x_1) where m is the slope, x_1 is the x coordinate of a point that the line passes through, and y_1 is the y coordinate of a point the line passes through.

Substituting, we get

y-(-1)=2/3(x-5)

In one hour, 17 cars drive through an intersection. Two-fifths of the 17 cars fail to come to a complete stop at the stop sign.
Rasek [7]

Answer:

Step-by-step explanation:

When you have a number (17) and want to know some fraction (2/5) of that number, you should multiply the number by the fraction.

17 * (2/5)

= (17*2)/5

= 34/5

= 6.8

You can then round this number up --> about 7 cars.
