Answer:
(q + 4) + (d - 3) + n
Step-by-step explanation:
You have to add all of them.
You have to add q, d, and n.
so q + d + n
and then you add four more q's so
(q + 4) + d + n
and then you lost 3 dimes so
(q + 4) + (d - 3) + n
and nothing happened to n so that is the answer.
Answer: 5/1 or just 5

Answer:
A. 87
B. i dont uderstand velocily sorry
Step-by-step explanation:
3*a=3*17=51
4*b=4*9=36
51+36=87
The smallest region that can be photographed is
5*7 = 35 square km
so we want to know how long it takes to zoom out to an area of
35 * 5 = 175 square km.
Notice that the length and width increase at the same rate, 2 km/sec, and they start out with a difference of two, so when the width has increased from 5 to x, the length will have increased from 7 to x+2. At the desired coverage area, then,
x(x+2) = 175
x^2 + 2x = 175
x^2 + 2x + 1 = 176 [completing the square]
(x+1)^2 = 176
x+1 = ±4√11
x = -1 ±4√11
Since a negative value for x is meaningless here, x must be
-1 + 4√11 = about 12.27 km
and the time it took to increast to that value was
(12.27 - 5) km / (2 km/sec) = about 3.63 seconds
Answer:
<h2>( 6 , 7 )</h2>
Step-by-step explanation:
The midpoint M of two endpoints of a line segment can be found by using the formula
From the question we have
We have the final answer as
<h3>( 6 , 7 )</h3>
