Answer:
A)
Step-by-step explanation:
Subtract 2c from both sides
5c-25-2c=2c+6-2c
3c-25=6
add 25 to both sides
3c-25+25=6+25
3c=31
Divide both sides by 3
3c/3=31/3
c=31/3

Supposing we begin with n=1, the first few terms of this arith sequence are
5, 1, -3, -7, and so on. 4 is the common difference.
<u>Answer:</u>
Given below.
<u>Explanation:</u>
Coordinates given: W( -4, -3 ) , X( 1 , -2 ), Y(2, -7 ) , Z( -3, -8)
To find the distance we will use the formula: distance=√((x2-x1)²+(y2-y1)²)
WX = √((1--4)²+(-2--3)²)
= √26
YZ = √((-3-2)²+(-8--7)²)
= √26
XY = √((2-1)²+(-7--2)²)
= √26
WZ = √(-3--4)²+(-8--3)²
= √26
WY = √(2--4)²+(-7--3)²
= 2√13
XZ = √(-3-1)²+(-8--2)²
= 2√13
Answer:
2 with the sqaure root of 12 is = 6.9 simp = 6.9
4 with the sqaure root of 10 is = 12.6 simp= 12.6
sum = 19.5
I hoped this helped! :)
