Answer:
Below in bold.
Step-by-step explanation:
x /18 = 12/10
10x = 18*12
x = 216/ 10
= 21.6.
10/w = 18/24
10/w = 3/4
3w = 40
w = 40/3 = 13 33 to the neaest hundredth.
Answer: D
Step-by-step explanation:
Answer: 45 ft
Step-by-step explanation:
and 15ft add 10ft to get 25ft
then subtract 70 from 25
In a standard binomial equation: ax² + bx + c = 0
To complete the square; divide the middle coefficient "b" in half and square it to find "c".
(-5/2)² = 25/4
x² - 5x + 25/4 = 25/4
completes the square:
(x - 5/2)² = 25/4
Options A, B and D are true.
