Answer:(x² + 14x)/(9x²)
Step-by-step explanation:
Explanation:To do this calculatio process:The first term: 2x/x² = 2/x.Then: (2/x) + (x - 4)/(9x).We should common the denominator by multiplying the denominators of the two terms (9x)(x) = 9x² and dividing each denominator by the common denominator.So, it will be equal:[(2)(9x) + (x - 4)(x)]/9x² = (18x + x² - 4x)/9x² = (x² + 14 x)/9x².

Step-by-step explanation:
A driver spent 45minutes to cover a distance of 120km
Convert minutes to hour
- 45 min = 45 /60 hr = 3/4 hr
Use the distance equation
Find the speed
Substitute the distance and time value and find the value of speed
- s = 120 / (3/4) = 120 * 4/3 = 160 km /h
Answer:
5 inches per hour

Answer:
FED ~ MLF
Step-by-step explanation:
∠L = ∠E
∠F = ∠F
Since both angles are congruent, that would mean all angles are congruent.
If all angles are congruent, then the triangles are always similar no matter the length of the sides.
