Answer:
f(-4)=-2(-4)²+8(-4)-10=-2×16-32-10=-74
Answer:
7
Step-by-step explanation:
I am assuming that the division problem looks like this:
-2| 1 2 -3 1
Going off that assumption, we will work this problem. The first thing you always do in the execution of synthetic division is to bring down the first number. Then multiply that number by the one "outside", which is -2, then put that number up under the next number in the line:
-2| 1 2 -3 1
-2
1
Now add the 2 and -2 and bring that down as a 0 and multiply the -2 times the 0:
-2| 1 2 -3 1
-2 0
1 0
Now add -3 and 0 to get -3 and multiply that -3 times the -2 and put the product up under the next numbe in line;
-2| 1 2 -3 1
-2 0 6
1 0 -3
Now add the 1 and the 6 to get the remainder:

Answer:
A. -9
Step-by-step explanation:
If one of the variables were negative than, it would not be able to equal 2/7.
Answers:
- AE = 26
- AN = 58
- CT = 22.5
- Perimeter of triangle AEN = 127
=========================================================
Work Shown:
Because points C, P, and T are midpoints of the sides of triangle AEN, this means the segments CP, PT, and CT are midsegments of triangle AEN.
The segment PT = 13 is a midsegment of the larger triangle, and it is parallel to the side AE. Recall the midsegment is half as long as its parallel side.
This means,
PT = (1/2)*AE
2*PT = AE
AE = 2*PT
AE = 2*13
AE = 26
---------------
We'll use the same idea to find AN
CP = (1/2)*AN
2*CP = AN
AN = 2*CP
AN = 2*29
AN = 58
---------------
And we can also say,
CT = (1/2)*EN
CT = (1/2)*43
CT = 22.5
----------------
Add up the sides of triangle AEN to find its perimeter
Perimeter of triangle AEN = (AE)+(EN)+(AN)
Perimeter of triangle AEN = (26)+(43)+(58)
Perimeter of triangle AEN = 127
Let width = 4x
Therefore length must equal 4x - 9
4x + 4x - 9= 90
8x - 9 = 90
(plus 9 to both sides)
8x = 99
(divide both sides by 8)
x= 12.375
width = 4 x 12.375
width = 49.5
length = 49.5 - 9
length = 40.5
