Answer:
The answer to your question is 4
Step-by-step explanation:
Data
calculate x
Process
1.- Calculate the length of RT using trigonometric functions
sin 60 = 2√3 / RT
-Solve for RT
RT = 2√3 / sin 60
-Simplification
RT = 2√3 / √3/2
RT = 4
2.- Calculate RQ using trigonometric functions
tan 45 = RQ / RT
-Solve for RQ
RQ = RT tan 45
-Substitution
RQ = 4 (1)
-Result
RQ = x = 4
Answer: 30 Ribbons
Step-by-step explanation:
24 divided by 4, which is the numerator.
24/4 = 6
He can attach 6 ribbons every 12 Minutes (1/5 of an hour)
5 * 5 (the other 5 is from the denominator)
30 ribbons

Answer:
Step-by-step explanation:
Given equation:
Factor out 3 from the first 2 terms:
Divide the coefficient of x by 2 and square it: (-3 ÷ 2)² = 9/4
Add this inside the parentheses and subtract the distributed value of it outside the parentheses:
Factor the parentheses and combine the constants:
