Answer:
Step-by-step explanation:
Cross multiply and reduce to lowest possible terms
(Reduced 15 and 360 by 3)
(Reduced 72 and 120 by 24)
(cancelled out 5 in both numerator and denominator)
D is the only viable answer among these, as A, B, and C all contain two even integers which, by definition, have a greatest common factor of 2.
<em>Correction: </em>I was incorrect in saying that <em>all </em>even integers have a greatest common factor of 2; 2 is at least guaranteed to be <em>one of the common factors </em>in any group of even numbers, but these examples all have it as their <em>greatest </em>common factor as well.
Answer:
c
Step-by-step explanation:
just plug each coordinates
5=x
18=y
if its tru for both then thats the answer
The longest of the four side lengths is 24 cm
<h3>How to find the value of the longest of the four side lengths?</h3>
The given parameters are:
Perimeter, P = 90 cm
The lengths are consecutive integers
Let the smallest be
Smallest = x
So, we have
P = x + x + 1 + x + 2 + x + 3
Evaluate the like terms
P = 4x + 6
Substitute P = 90 cm in P = 4x + 6
4x + 6 = 90
Subtract 6 from both sides
4x = 84
Divide by 4
x = 21
The longest side is
Longest = x + 3
This gives
Longest = 21 + 3
Evaluate
Longest = 24
Hence, the longest of the four side lengths is 24 cm
