You should really learn these, since later when you go into college they will also test you about graphs and such.

To do this, focus on one point of the pre-image A. Now, look at this point, and see how it gets there to the actual image. In this case, it is translated 10 units to the right, and then 10 units down. If it was reflected across the y or x axis, the shape would be flipped, this pre-image was simply just translated to another place.

So, the answer you're looking for is <span>B) translated 10 units to right and then 10 units down </span>

The base of an isosceles triangle is 2 cm. The perimeter of the triangle is 10 cm.

Answer and Step-by-step explanation:

$Greetings!$

$Let's~solve~your~question!$

$To~find~the~length~of~equal~sides~of~an~isosceles~triangle,~we~use~the~following\\formula.$

$\boxed{~P=2a+b~}$

$Now,~solving~for~``a":$

$P=\frac{P}{2} -\frac{b}{2}$

$=\frac{10}{2}-\frac{2}{2}$

$=5-1$

$=4$

$Thus,~each~equal~sides~of~an~isosceles~triangle~is~4cm.$

Find the area of the rhombus.

Inessa [10]

A=24

Find the area by multiplying both diagonals and dividing them by 2. Like so: And you might be wondering how to do that. By using the pythagorean theorem and some simple addition, you could get the answer. One diagonal is 8 and the other is 6....so, 8x6=48....48/2=24

Please let me know if you have any other questions!
