Answer:

A) P = 6n + 8

Step-by-step explanation:

Given:

Perimeter of the 1 triangle = 24

Perimeter of the 2 triangle = 30

Perimeter of the 3 triangle = 36

Let's check with option A.

P = 6n + 18, where "n" is the number in the figure.

Plug in n = 1, we get

P = 6(1) + 18

= 6 +18

P = 25 True.

Plug in n =2, we get

P = 6(2) + 18

= 12 +18

P = 30 True.

Plug in n =3, we get

P = 6(3) + 18

P = 18 + 18

P = 36, true.

Therefore, the answer is A. P = 6n + 18

Thank you.

Mekhanik [1.2K]

Answer:

C and e

Step-by-step explanation:

the 50r represents the commision he receives for each refrigerator he sells, and the 250 is the base salary and it’s bigger than, >, because he needs to earn MORE than 900 and you get D by solving the inequality, 50r >900, r>15

would be amazing if you marked this brainliest :)

If PQR is a triangle,given that /PQ\=15m, /QR\=17m and /RP\=18m.Find the area of the triangle to the nearest whole number.

nydimaria [60]

Answer:

118.3 m²

Step-by-step explanation:

Step 1. Calculate the semiperimeter (s).

s = (p + q + r)/2

s = (17 + 18+ 15)/2

s = 50/2

s = 25 m

===============

Step 2. Calculate the area (A).

Use Heron’s formula:

$A = \sqrt{s(s-p)(s-q)(s-r)}$

$A = \sqrt{25(25-17)(25-18)(25-15)}$

$A = \sqrt{25\times8\times7\times10}$

$A = \sqrt{14 000}$

$A = 20\sqrt{35}$

A = 118.3 m²
