Answer:
(a) 156 cm²
Step-by-step explanation:
The total surface area of the 12 blocks can be computed by first finding the surface area of one block. That result can then be multiplied by 12. The area of one rectangular prism is given by the formula ...
A = 2(LW +H(L +W))
A = 2(4·1 +1/2(4+1)) = 2(4 +5/2) = 13 . . . cm²
The area of 12 such prisms will be ...
12 × (13 cm²) = 156 cm²
Victor needs 156 cm² of fabric to cover 12 blocks.

<em>Additional comment</em>
This problem offers an opportunity to exercise your number sense. The area of the largest surface of one block is (4 cm)×(1 cm) = 4 cm². 12 of these surfaces will have an area of 48 cm². This is only part of the total area, so the only reasonable choice among those offered is 156 cm².
<span>This is the case because quadratum is the Latin word for square, and since the area of a square of side length x is given by x2, a polynomial equation having exponent two is known as a quadratic ("square-like") <span>equation</span></span>

Answer:
(-2, 1) and (0, 3) has the slope of m = 1 and the equation is y = x + 3
(0, -2) and (3, -5) has the slope of m = 1 and the equation is y = -x - 2
