Answer:

Step-by-step explanation:

To determine which point is a solution, substitute into the left side of the equation and if it is equal to the right side then it is a solution.

(- 4, 4 )

- 3(- 4) - 4 = 12 - 4 = 8 ≠ 6 ← Not a solution

(- 3, 3 )

- 3(- 3) - 3 = 9 - 3 = 6 ← Solution

Thus (- 3, 3 ) is the only solution → B

A cuboid has side lengths 3cm, 4cm and 7cm. A cylinder with a height double that of the longest side of the cuboid has the same

mart [117]

Step-by-step explanation:

Longest side of cuboid: 7cm

Height of cylinder:

2 × 7 = 14 cm

Volume of cuboid:

7x3x4=84 $cm^3$

Volume of cylinder:

$84=14\pi r^2 \\r=\sqrt{\frac{6}{\pi} } \ \ \ cm\\r=1.38 \ cm\\$

Surface area of the cylinder:

$\pi r^2 + 2 \pi r h$

$6+2\pi (\sqrt{\frac{6}{\pi} } ) (14)$

=128 cm^2
