<span>In two similar triangles, like the one we see above, the ratio of their areas is the square of the ratio of their sides.
Based on the graph, we see that BD is 3 times larger than BA. This means that the area of DBE will be 3</span>² times larger, or 9 times larger, than the area of ABC.
Area of ABC = 3 square units
Area of DBE = 3 * 9 = 27 square units
Answer is A.
Y=4 is the answer for this
Answer:
3x + 7y > 21
Step-by-step explanation:
3x + 7y > 21
where:
x = number of field goals needed to win
y = number of touchdowns (plus extra point) needed to win
Since your team is 21 points behind and you want to win the game, not tie it, the number of field goals and touchdowns must result in a number higher than 21, not equal to or higher than.
En este problema simplemente tenemos que usar la suma de fracciones.
Veremos que entre ambos tienen un frasco entero de miel.
Sabemos que Clauida tiene 3/6 de un frasco de miel, y el hermano tiene 9/18 de un frasco de miel.
En total, entre ambos, tienen:
3/6 + 9/18
Para poder realizar esta suma tenemos que tener el mismo denominador en ambas fracciones, asi que podemos simplificar.
en 9/18 si dividimos numerador y denominador por 9 obtenemos:
9/18 = 1/2
en 3/6 si dividimos numerador y denominador por 3 obtenemos:
3/6 = 1/2
Así:
3/6 + 9/18 = 1/2 + 1/2 = 1
Entre ambos tienen un frasco entero de miel.
