Three triangles are shown on the centimetre grid. A, B,C. A\ Which triangle has the largest area? b\ work out of the area of the triangle. Give your answer as a decimal.

Step-by-step explanation:

The three triangles are shown in the image attached.

Remember that the area of a triangle is determined by

Where is the base and is the height.

The first triangle is a right triangle with height of 4 units, and a base of 5 units. So, its area is

Therefore, the first triangle (at the left), has an area of 10 square units.

The second triangle (middle), has a height of 5 units and a base of 4 units, so its area is

Therefore, the second triangle has an area of 10 square units.

The third triangle has a height of 5 units, and a base of 4 units. Therefore, it also has an area of 10 square units.

Therefore, all three triangles are congruent.

step-by-step explanation:

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
