(8p - 2) (6p+2) help plz

qaws [65]

Answer:

$48p^2+2p-4$

Step-by-step explanation:

We can use the FOIL method to expand two multiplied binomials. It states that $(a+b)(c+d)=ac+bc+ac+bd$ . The FOIL method stands for First(first terms) outer(outer terms) inner(inner terms) last(last terms).

So, we can expand our binomials now!

$(8p-2)(6p+2)=(8p)(6p)-2(6p)+(8p)(2)-2(2)=48p^2-12p+14p-4=\boxed{48p^2+2p-4}$

Answer:

A. Eric rode 2 more miles per week than Kim rode

Step-by-step explanation:

Number of miles Kim rode bicycle in 9 weeks = 135 miles

Let x be the number of miles per week.

135miles => 9 weeks

x miles => 1 week

$x = \frac{135}{9}$

$x = 15$

Kim rode the bicycle 15 miles per week

Number of miles Eric rode bicycle in 6 weeks = 102 miles

Let x be the number of miles per week Eric rides the bicycle.

102 miles => 6 weeks

x miles => 1 week

$x = \frac{102}{6}$

$x = 17$

Kim rode the bicycle 17 miles per week

Comparing the number of miles per week they rode, we would conclude that: "Eric rode 2 more miles per week than Kim rode".

A regular hexagon has sides 2 feet long. What is the exact area of the hexagon? What is the approximate area of the hexagon?

nexus9112 [7]

The formula for the area of a hexagon is

$A=\frac{3\sqrt[]{3}}{2}s^2$

where 's' is the length of one side of the regular hexagon.

The side of our regular hexagon is 2 feet, therefore, its area is

$\begin{gathered} A=\frac{3\sqrt[]{3}}{2}\cdot(2)^2=6\sqrt[]{3} \\ 6\sqrt[]{3}=10.3923048454\ldots\approx10 \end{gathered}$

The exact area of the hexagon is 6√3 ft², which is approximately 10 ft².
