Answer:
3n^2+n-2
Step-by-step explanation:
Coefficient is the number that we multiply an expression that contains a variable. In all the expressions above the variable is n.
Some examples:
Coefficient of n^2 is 1.
Coefficient of n in n^2+2n+1 is 2.
Solution:
In 5n^2+6n-1 the Coefficient of n is 6.
In 2n^2+5n+1 the Coefficient of n is 5.
In 40^2 - n +9 the Coefficient of n is - 1.
In 3n^2 +n - 2 the Coefficient of n is POSITIVE 1.
We tend to not write 1*n because 1*n=n.
The answer is 33 years .
Here's why:
10% of 3 is .3
Just move the decimal to the left .
.3 times 33=9.9
9.9~10
X + 5y = 14
5y = -x + 14
y = -1/5x + 14/5.....the slope here is -1/5. A perpendicular line will have a negative reciprocal slope. All that means is flip the slope and change the sign. So our perpendicular slope will be 5. See how I flipped -1/5 making it -5/1...and then changed the sign, making it 5.
y = mx + b
slope(m) = 5
(-5,-2)....x = -5 and y = -2
now we sub and find b, the y int
-2 = 5(-5) + b
-2 = -25 + b
-2 + 25 = b
23 = b
so ur perpendicular equation is : y = 5x + 23 <==
x is the middle line because it divides each catheter into two equal parts.
==> x is half the hypotenuse.
