In Russia long ago there’s was a man
The base of this rectangle is 4
cm.
The height of this rectangle is 6
cm.
The area of this rectangle is 24
cm2.
Answer:
t = 1 3/7 hours
Step-by-step explanation:
For plane 1
distance = rate *t
d1 = 40 *t
For plane 2
distance = rate * time
d2 = 100 * t
We know that d1+d2 = 200 (the planes will meet)
We know that the times will be the same because the leave at the same time.
Substitute in d1 =40t and d2 = 100t into d1+d2 = 200
d1+d2 = 200
40t + 100t = 200
Combine like terms
140t = 200
Divide each side by 140
140t/140 = 200/140
t= 200/140
t= 20/14
t = 10/7
t = 1 3/7 hours
Answer:
Ok ive done that too, but my answer was B.
Step-by-step explanation:
The solution to the answer is as follows:
We have...
y = (x + 9)(x + 6)
Then...
<span>y = (x + 5(9)) (x + 5(6))
</span>
= (x + 45) (x + 30)
<span>Hence, the x-intercepts are -45 and 30.
