Answer:
20, 21
Step-by-step explanation:
The number halfway between the middle two integers is the average of the four:
78/4 = 19.5
Then the four integers are 18, 19, 20, 21.
The 3rd and 4th integers are 20 and 21.
Answer: <em>x=-4</em>
Step-by-step explanation:
<em>-4x=16</em>
<em>Divide by -4 on each side to cancel it out</em>
<em>x=-4</em>
Answer:
d. 4x^2-20x-25
Step-by-step explanation:
So, we have to multiply (2x-5) by itself. That gives:
(2x-5) (2x-5) = 2x (2x-5) - 5 (2x-5) = 4x² - 10x -10x + 25
so, the correct answer is 4x² - 20x + 25
It's just important to multiply each component carefully by using the distributive property.

Answer:
<em>v = 3.75 mph</em>
Step-by-step explanation:
<u>Constant speed motion
</u>
An object travels at a constant speed if the ratio of the distance traveled by the time taken is constant.
Expressed in a simple equation, we have:
Where
v = Speed of the object
d = Distance traveled
t = Time taken to travel d.
Sam walks from home to school for a distance of d=0.75 miles in t=12 minutes. To calculate the speed, we need to convert the time to hours.
t=12/60 = 0.2 hours. Now compute the speed:
v = 3.75 mph
