Well on 3 for the circle its 1/2×15×8=60
Answer:
first one: B and C
Second one: x=12, y=10 so the answer is B.
Step-by-step explanation:
First one: Irrational numbers are any numbers that go on forever in the decimal without ever repeating. Any square roots of numbers that aren't perfectly square, such as 4 and 9, are irrational. And anything with pi, or 
, is always irrational.
Second one: 144 and 100 are perfect squares, meaning it can be created by multiplying the same number by itself, in this case 12 and 10. Subtract those and you get 2.

Its Easy 63137x7821/767382(87438>989)8788123.
Step-by-step explanation:
Usando un sistema de ecuaciones, se encuentra que ese número es n = -3 o n = 3.
<h3>¿Qué es un sistema de ecuaciones?</h3>
Un sistema de ecuaciones es cuando dos o más variables están relacionadas y las ecuaciones se construyen para encontrar los valores de cada variable.
En este problema, la variable es el número n.
El quintuple de un número cuadrado disminuido en 9 da como resultado 36, o sea, la ecuación es:
5n² - 9 = 36
5n² = 45
n² = 9
n = -3 o n = 3.
