Well it's a cube all sides should be the same size therefore 7 cm as it already says
Simplify brackets
16/20 = t + -13/20
Simplify 16/20 to 4/5
5/5 = t - 13/20
Add 13/20 to both sides
4/5 + 13/20 = t
Simplify 4/5 + 13/20 to 29/20
29/20 = t
Switch sides
<u>t = 29/20</u>
Shortest to tallest: Plant A, Plant B, Plant C.
Given:
Plant A 1/3 inch tall
Plant B 3/4 inch tall
Plant C 5/6 inch tall
Order from shortest to tallest.
First we need to get the least common multiple of the three fractions.
Multiple of 3: 3, 6, 9, 12
Multiple of 4: 4, 8, 12, 16
Multiple of 6: 6, 12, 18
Their least common multiple is 12. We need to multiply each fraction by the number that will give the product of 12 to the denominator.
Plant A: 1/3 * 4/4 = 4/12
Plant B: 3/4 * 3/3 = 9/12
Plant C: 5/6 * 2/2 = 10/12
Since the denominator is common, we will use the numerator as basis in ordering the plants from shortest to tallest.
4 is less than 9 and 9 is less than 10.
so, Plant A is the shortest, Plant B is the medium height, and Plant C is the tallest.
Step-by-step explanation:
(4-x)(4-x)=16-4x-4x+x= 16-7x
