Since 36x² + 60x + 25 is the perfect square trinomial, we use this formula a² + 2ab + b² = (a + b)². Hence, the solution is (6x + 5)²
Answer:
x = 11.4 m
y = 21 m
man's shadow = 9.6 m
Step-by-step explanation:
measure of third angle must be 50 degrees (180 - (40 + 90))
you can take tan50° = 15/y and 'y' will equal approx. 21
to find 'x' you can take tan21° = (21-x) /25 and 21 - x = 25 · tan21°
21 - x = 9.6
-x = -11.4
x = 11.4
man's shadow is the difference of 21 and 11.4, which is 9.6
Answer:
Step-by-step explanation:
you would show x and y lines and title frequency to side and colours to bottom
0-40 on the y axis title is frequency
and on bottom graph put the colours. red blue and green always using equal intervals for names or time or colours along the x axis.
Answer:
32 cars
Step-by-step explanation:
we know that he can paint 12 cars in 3 weeks.
