Given the calculations shown, find the dimensions of the prism.
ra1l [238]

The dimensions of the prism has height of 7 units, width of 10 units and length of 10 units.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

From the prism:

Perimeter P = 2(w + l)

40 = 2(w + l)

w + l = 20   (1)

Also:

Base area (B) = wl

100 = wl   (2)

from equation 1 and 2:

w = 10, l = 10

The dimensions of the prism has height of 7 units, width of 10 units and length of 10 units.

Which of the relations given by the following sets of ordered pairs is not a function?
-Dominant- [34]

Answer:

Hi, there your answer will be C.

Step-by-step explanation:

The reason why is because X(Input) can not be repeated the same

for example the coordiante( 1,3) and (1,4). See there are two ones which make them not function

Also, if you're having trouble with Functions and nonfunctions

REMEMBER THS

Function: X and y has to be separarte  and can't have the same X

NON-FUNCTION- WHEN X REPEATS ITSELF

Hope this helps :)
