Answer: -2
Step-by-step explanation:
The information in the question can be used to form an equation which goes thus:
2nd term = a + d = 4 ...... i
5th term = a + 4d = 22 ....... ii
From equation i
a = 4 - d ........ iii
Put equation iii into ii
a + 4d = 22
(4 - d) + 4d = 22
4 - d + 4d = 22
4 + 3d = 22
3d = 22 - 4
3d = 18
d = 18/3
d = 6
Commons difference is 6
Since a + d = 4
a + 6 = 4
a = 4 - 6
a = -2
The first term is -2
Answer: k=0 or k=−10
Step-by-step explanation: Let's solve your equation step-by-step.
3k(k+10)=0
Step 1: Simplify both sides of the equation.
3k2+30k=0
Step 2: Factor left side of equation.
3k(k+10)=0
Step 3: Set factors equal to 0.
3k=0 or k+10=0
k=0 or k=−10
3x+2=14
-2 -2
3x=12
/3 /3
X=4
Answer: B) 6
Explanation:
Segment BA is half as long as ZY, since BA is a midsegment.
This means ZY is twice as long as BA
ZY = 2*BA
2*BA = ZY
2*(x-1) = 10
2x-2 = 10
2x = 10+2
2x = 12
x = 12/2
x = 6
Note how this leads to BA = x-1 = 6-1 = 5, which is half as long as ZY = 10.
Answer:
n=6
Step-by-step explanation:
six less than what number is zero
n-6 =0
add 6 to each side
n-6+6 =0+6
n = 6
