Answer:
They are both right becuase if you just take away 1 from 20 and 10 you get 2 and 1. For the 4:2 one take away 1 and mutiply by 2 equalling 4:2 but they are still the same thing.
Step-by-step explanation:
Answer:
They should insert that y value into the other equation.
Step-by-step explanation:
Answer:
1 inch by 36 inches
or
2 inches by 18 inches
or
3 inches by 12 inches
or
4 inches by 9 inches
Step-by-step explanation:
A right triangle has an area of 18 square inches
The triangle is not an isosceles triangle
The area of a right triangle is given by;
× base(b) × height(h)
In our case, the base and the height of the triangle are known as legs
So,
× b × h = 18 square inches
b × h = 18 × 2 = 36 square inches
The possible factors of 36 (or lengths of the legs) that could give an area of 18 square inches are:
Base by Height:
1 inch by 36 inches
or
2 inches by 18 inches
or
3 inches by 12 inches
or
4 inches by 9 inches
Coordinates of vertices of new triangle:
A´(0,0), B´(-12,0), C´(-6,12).
This transformation is dilatation, with the origin as the center of dilatation and the scale factor of the dilatation : s=3. A dilatation changes the size of a figure, while the shape of figure does not change.
Triangle A´B´C´ (image) is similar to triangle ABC (pre-image) because their corresponding angles are equal in measure and the ratio of their corresponding sides are in proportion (in attachment).
