Answer:
D. -2x - 8
Step-by-step explanation:
1) Simplify 1/3(6x+15) to 6x+15/3
-6x+15/3 - 3
2) Factor out the common term 3.
-3(2x+5)/3 - 3
3) Cancel 3.
-(2x+5)-3
4) Remove parentheses.
-2x-5-3
5) Collect like terms.
-2x+(-5-3)
6) Simplify
-2x-8
U add 1.5 everytime
so the next 3 terms: 8, 9.5 and 11
Answer:
2n+5 =3
n=-1
The number is -1
Step-by-step explanation:
Let n be the number
Twice the number
2n
Plus 5
2n+5
is means equals
2n+5 =3
Now we want to solve
Subtract 5 from each side
2n+5-5 = 3-5
2n = -2
Divide each side by 2
2n/2 = -2/2
n = -1
The perimeter is about 82 yards
first, the perimeter of the rectangles is 30*2 = 60 (the 7 is not a part of the overall perimeter so we do not need to add it)
the "perimeter" (circumference) of the 2 semi circles = (22/7)*7 = 22by using the formula C = pi*d (2 semi circles of the same diamter = 1 circle)
now just add the 2 answers
22 + 60
= 82 yards
