Answer:
Step-by-step explanation:
2) l = 9 cm
b = 7 cm
h = 3 cm
Surface Area= 2*(lb + bh + hl)
=2*(9*7 + 7*3 + 3*9)
=2*(63 + 21 + 27)
= 2 * 111
= 222 cm²
Using the midpoint concept, it is found that the value of a is of a = 2.
<h3>What are the coordinates of the points?</h3>
Researching this problem on a search engine, the coordinates are given as follows:
<h3>What is the midpoint concept?</h3>
The midpoint between two points is the halfway point between them, and is found using the mean of the coordinates.
Hence the following system of equations can be built:
(b + 1 + 2a)/2 = 3.
b + 1 + 2a = 6.
b = 5 - 2a.
(a + 2 + 3b + 3)/2 = 5
a + 3b + 5 = 10
a + 3b = 5.
Since b = 5 - 2a, we have that:
a + 15 - 6a = 5.
5a = 10
a = 10/5
a = 2.
The value of a is of a = 2.

Easy peasy
the midpoint between

and

is

just average them
so given that (3,5) is the midpoint of (-4,5) and (x,y)

so by logic

and

times both sides by 2 for everybody
-4+x=6 and 5+y=10
add 4 to both sides for left one and minus 5 from both sides for right
x=10 and y=5
the coordinate of point C is (10,5)
the x coordinate is 10
Answer:
10 will be answer

Answer: D It is moving in a different direction as the kayak because it slowed Jaime down.
Step-by-step explanation:
Jaime can paddle her kayak at an average rate of 6 miles per hour in still water.
Distance = speed × time
After 2 hours of paddling north in a river, she traveled 8 miles. This distance covered was supposed to be
6 × 2 = 12 miles
Therefore, the following is true about the direction of the current in the river:
D It is moving in a different direction as the kayak because it slowed Jaime down.
