Answer:
x=11.5
Step-by-step explanation:
2x+8=-15
x=-23/2
x=-11.5
I'll draw it for you cause im nice.
Ok so if you have 5ft on a square, all the sides are 5ft.
That mean that if its in half, one of the sides will be 2.5ft.
Now you can add 2.5 + 2.5 + 5+5 = 15.
So its 15 ft.
A.
the area of a polygon is/
A= perimeter X apothem /2
A=500
apothem = 10
500 = (P * 10)/2
P =100
B. 100*7.95 = $795
C.
60*100= 6,000
6,000 * $7.95=

Answer: the increase each year is 423 tv sets
Step-by-step explanation:
The formula for determining the sum of n terms of an arithmetic sequence is expressed as
Sn = n/2[2a + (n - 1)d]
Where
n represents the number of terms in the arithmetic sequence.
d represents the common difference of the terms in the arithmetic sequence.
a represents the first term of the arithmetic sequence.
From the information given,
n = 10 years
a = 1000
S10 = 29035
We want to determine d which is the amount by which the production increased each year. Therefore, the sum of the first 10 years would be
29035 = 10/2[2 × 1000 + (10 - 1)d]
29035 = 5[2000 + 9d]
29035/5 = [2000 + 9d]
9d = 5807 - 2000 = 3807
d = 3807/9 = 423
F(-1)=2
F(2)=-1
F(3)=-3
The f(x) part is the input and the stuff after is the output
