Answer:
the answer is 12 cm
Step-by-step explanation:
Because of 8 cm on the small one, the 16 is double that, which means that 6 on the small would be 12 on the large
Answer:
6 laps.
Step-by-step explanation:
On Monday she runs 2x + 8 miles, where x miles = the length of the trail.
On Tuesday she runs 4x + 4 miles and this is the same distance as Monday, so
2x + 8 = 4x + 4
4 = 2x
x = 2 miles which is the length of the trail.
So each day she runs 4(2) + 4 = 12 miles.
So on Saturday she runs 12/ 2 = 6 laps.
Answer:
x = 40 , y = 70
Step-by-step explanation:
y = 70°
x° = 180° - 2 × 70° = 40°
Answer:
y = x² - 13x + 36
Step-by-step explanation:
Given the zeros x = 4 and x = 9, then the corresponding factors are
(x - 4) and (x - 9)
The polynomial is then the product of the factors
y = (x - 4)(x - 9) ← expand using FOIL
y = x² - 13x + 36
