Answer:

x =  \boxed{2}\:  and\: x =  \boxed{ \frac{5}{2} }

Step-by-step explanation:

2 {x}^{2}  - 9x + 10 = 0 \\  \\ 2 {x}^{2}  - 4x - 5x + 10 = 0 \\  \\ 2x(x - 2) - 5(x - 2) = 0 \\  \\ (x - 2)(2x - 5) = 0 \\  \\ x - 2 = 0 \:  \: 2x - 5 = 0 \\  \\ x =  \boxed{2} \: and \: x =  \boxed{ \frac{5}{2} } \\  \\

A shape is shown on the centimetre grid below.
krok68 [10]

Answer:

The area of the shape after it has been enlarged by

scale factor 2 will be: 10 cm²

Step-by-step explanation:

The Area is basically a measure of how much space in square units there is inside an object.

As the shape is shown on the centimeter grid.

  • The shape clearly occupies the space of 5-centimeter squares.

We also know that If the scale factor > 1, the image is enlarged.

As we know to determine the area of the shape after it has been enlarged by scale factor 2, all we need to do is to multiply the area of the original shape by 2.

The area of original shape = 5 cm²

The area of the shape after the dilation by a scale factor 2 = 5 × 2 = 10 cm²

Thus, the area of the shape after it has been enlarged by

scale factor 2 will be: 10 cm²
