The difference between the y-coordinates is 7 units. If the area is to be 42 square units, the missing coordinates must be 42/7 = 6 units to the right of those shown.
B = A +(6, 0) = (-4, 4) +(6, 0) = (-2, 4)

D = C +(6, 0) = (-4, -3) +(6, 0) = (-2, -3)

The appropriate choice is the last one, ...
(-2, 4) and (-2, -3)

A pencil holder shaped like a triangular prism the height of the pencil is 12cm and the volume is 216cm what is the area of the

mamaluj [8]

Given that Volume of triangular prism = 216 cubic centimetre

Given that Height of the pencil = 12 centimetre

Now we have to find the area of the base of the prism means find the area of triangular part.

Volume of triangular prism is given by formula:

Volume of triangular prism = (Area of base) x (Height of the prism)

now plug the given values

216= (Area of the base) x 12

$\frac{216}{12}=$ Area of the base

18= Area of the base

Hence final answer is 18 square centimetres.

O triangulo retângulo ABC é isósceles, e a área do quadrado BCDE é 128 cm². Qual é a medida do lado AB?

adell [148]

áreaBCDE = 128 cm² => BC = 8√2 cm

BC = AB√2 =>

8√2 = AB√2 =>

AB = 8 cm
