Answer:
add 21 to both sides to get everything on one side
x^2 - 10x + 21 = 0
do factorization, guess and check
(x - 7) (x -3) = 0
x =7, and x =3
You find the volume by multiplying the legnth x width x height
Answer:
Step-by-step explanation:
AOB=180°
ZOB =c=31°
XOY=b= 40°
AOY= a+b =24+40 = 64°
YOZ =180-a-b -c=180-24-40-31=85°
Hope this helpsxx
Answer:
0 feet.
Step-by-step explanation:
h = -16t^2 + 12t + 4
h = -4(4t^2 - 3t - 1)
= -4(4t + 1)(t - 1)
After 1 second height = -4 * 1 * 0 = 0 feet.
