Answer:
a = -2
Step-by-step explanation:
-(5a+6)=2(3a+8)
-5a -6 = 2*3a +2*8
-5a -6 = 6a +16
-5a -6a = 16+6
-11a = 22
a= -22/11
a = -2
Let's call the width of our rectangle
and the length
. We can say
, since the length is equal to 4 cm greater than the width.
Also remember that the perimeter of a rectangle is the sum of two times the width and two times the length, or
. To solve this problem, we can substitute in the information we know, as shown below:




Now, we can substitute in the width we found into the formula for length, which is
:


The width of our rectangle is
cm and the length of our rectangle is 
Subtract 17 from both sides , x=1
Answer:
common ratio
Step-by-step explanation:
When you have a geometric sequence
an = a1 r^(n-1)
The term r is call the common ratio, which is the number we are multiplying by each time
Answer:
JK = 6 units
3 equal parts
-7
Step-by-step explanation:
The total distance for JK = -3 - -9 = -3+9 = 6
The length of JK = 6 units
ratio 1:2 total is 3
Divide JK into 3 equal parts
When we divide into 3 equal parts, we split the line at -7 and -5
To have the ratio at 1 to 2 take the 1st point -7
