The vertices of ABC are A(-2, 2), B(6,2), and CO, 8). The perimeter of ABC?

Alexxx [7]

Answer:

Perimeter = 22.809836694575

Step-by-step explanation:

A(-2, 2) ; B(6,2) ; C(0, 8)

$AB=\sqrt{\left( 6--2\right)^{2} +\left(2-2 \right)^{2} } =\sqrt{64} =8$

$AC=\sqrt{\left( 0--2\right)^{2} +\left(8-2 \right)^{2} } =\sqrt{40} =2\sqrt{10}$

$BC=\sqrt{\left( 0-6\right)^{2} +\left(8-2 \right)^{2} } =\sqrt{72} =6\sqrt{2}$

Then

The perimeter of ΔABC = AB + BC + AC

$=8+6\sqrt{2} +2\sqrt{10}$

= 22.809836694575

Arithmetic sequence help!!!!

andrew-mc [135]

a₅ = 10

a₁₀ = 20

a₁₅ = x

-------------------------------------------------------------------------------------------------------------------

Note that from a₅ to a₁₀, there is a addition of 10. This means that for every x(₅) jump, you add 10 to the whole number.

-------------------------------------------------------------------------------------------------------------------

So in this case:

a₁₀ = 20

a₁₅ = x

a₁₀ (+₅) = 20 (+10)

a₁₅ = 20 + 10

a₁₅ = 30

Note that: a₁₅ = x = 30

-------------------------------------------------------------------------------------------------------------------

x = 30, or (A) is your answer

-------------------------------------------------------------------------------------------------------------------

hope this helps
