Answer: B. x = 150
Step-by-step explanation:
x/5 = 30
x = 30 * 5
x = 150
H represents the number of hours:
-13+5h=12
5h=12+13 (add 13 to both sides)
5h=25
h=25÷5 (divide both sides by 5)
h=5
After 5 hours the temperature will be 12°F. If it was 4 a.m. 5 hours ago then now it's 9 a.m. (4+5=9)
Hope this helped.
Hello from MrBillDoesMath!
Answer:
4( x + 1.5)^2 + 0
Discussion:
4x^2 + 12x + 9 = => factor "4" from first 2 terms
4 (x^2 + 3x) + 9 = => complete the square, add\subtract (1.5)^2
4(x^2 + 3x + (1.5)^2) - 4 (1.5)^2 + 9 =
4 ( x + 1.5)^2 + ( 9 - 4(1.5)^2) = => as (1.5)^2 = 2.25
4 ( x + 1.5)^2 + ( 9 - 4(2.25)) = => as 4 ( 2.25) = 9
4 ( x+ 1.5)^2 + 0
Thank you,

Answer:
18,20
Step-by-step explanation:
Start aat the -10, go up to the 5, its 15, so if its 15 to one end go the other way and you get 20
