Answer:
+ 9x - 5
Step-by-step explanation:
Take the whole rectangle and subtract the middle so
4x^2 + 4x + 1 - (x^2 -5x + 6) which is actually -x^2 + 5x -6
so 3x^2 + 9x -5
You cant really make a graph online but yiu have to know how many weeks she is saving for how much money she needs to save and once you find that out you multiply 8 by the number of weeks she is saving for. or take the number of how much money she needs to save and divide it by 8
987,164.302
I assume this is what you meant, sorta
9: hundred thousands
8: ten thousands
7: thousands
1: hundreds
6: tens
4: ones
.
3: tenths place
0: hundredths place
2: thousandths place
Answer:
It would be about 1.3 a piece.
Step-by-step explanation:
If there is 8 slices and six friends i think u would divide 8 by 6 which is 1.3 repeating which rounds up to 1.3
(Brainliest plz?)
First we define a variable:
x: length of the shortest side of the triangle.
Then, using the Pythagorean theorem we have:
(x + 8) ^ 2 = x ^ 2 + (x + 7) ^ 2
Rewriting we have:
x ^ 2 + 16x + 64 = x ^ 2 + x ^ 2 + 14x + 49
Clearing x we have:
64 - 49 = 2x ^ 2 - x ^ 2 + 14x - 16x
64 - 49 = 2x ^ 2 - x ^ 2 + 14x - 16x
15 = x ^ 2 - 2x
x ^ 2 - 2x - 15 = 0
The roots of the polynomial are:
x = -3
x = 5
We discard the negative root because it is a dimension.
Then, the perimeter is:
P = (x + 7) + (x + 8) + x
P = (5 + 7) + (5 + 8) + 5
P = 30
Answer:
the perimeter of the triangle is:
P = 30
