Answer:
D
Step-by-step explanation:
With no middle term, we factor the quadratic into two binomials of the form (x+a)(x-a) where a is the same number. 64 factors only into 8(8) where the factors are equal. We write in the form (x+8)(x-8).
To find the root or x-intercept, we set equal to 0.
(x+8)(x-8)=0
x=-8,8.

Answer:
10.5.
Step-by-step explanation:
By similar triangles:
IJ / 21 = 8 /(8+8) = 1/2
IJ / 21 = 1/2
IJ = 1/2 * 21
= 10.5.
It will take Ahmad 12 hours to drive 864 miles
Step-by-step explanation:
- Step 1: Find the speed of Ahmad.
Distance = 360 miles
Time = 5 hours
⇒ Speed = Distance/Time = 360/5 = 72 miles/hour
- Step 2: Find the time required to drive 864 miles
⇒ Time = Distance/Speed = 864/72 = 12 hours
