Answer:
this is how you solve it so what you gotta do is ...The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other. Once you know the constant of proportionality you can find an equation representing the directly proportional relationship between x and y, namely y=kx, with your specific k.
Step-by-step explanation:
Answer:
Below.
Step-by-step explanation:
The zeroes are at x = -2, 0, 1 and 3 so the factors are
(x +2)
x
(x - 1)
(x - 3)

Step-by-step explanation:
Given:
Right triangular prism
To find:
The surface area of the right triangular prism
Solution:
<u>Using nets of the prism:</u>
Area of large rectangle = length × width
= 7 × 5
Area of large rectangle = 35 square units
Area of middle rectangle = length × width
= 7 × 4
Area of middle rectangle = 28 square units
Area of small rectangle = length × width
= 7 × 3
Area of small rectangle = 21 square units
Area of top triangle =
Area of top triangle = 6 square units
Area of bottom triangle =
Area of bottom triangle = 6 square units
Total surface area = 35 + 28 + 21 + 6 + 6
= 96 square units
The surface area of the right triangular prism is 96 square units.
