8 laps * 400 m + 4 laps *400 + 8 laps * 400 m + 4 laps *400 + 8 laps * 400 m =
3200 + 1600 + 3200 + 1600 + 3200 = 12800 m = 12,8 km

Rewrite the following polynomial in standard form 5x-4-3x²+2x²

Lunna [17]

The standard form of the polynomial is expressed as $P(x)=-x^2+5x - 4$

<h3 /><h3>The standard form of a polynomial</h3>

The standard form of a polynomial is degree 3 is expressed as:

$P(x) = ax^3+bx^2+cx+d$

Given the expression 5x-4-3x²+2x², we are to write it in standard form. The standard form is expressed as shown:

Collect the like terms;

$5x-4-3x^2+2x^2$

$-3x^2+2x^2+5x-4|\\$

Group the terms:

$P(x) = (-3x^2+2x^2+5x-4)\\P(x)=-x^2+5x - 4$

Hence the standard form of the polynomial is expressed as $P(x)=-x^2+5x - 4$

If two sides in one triangle are 9 and 21 , then the third side might be

slamgirl [31]

Answer:

13

Step-by-step explanation:

there is a rule that says that if you add any 2 sides, it should be more than the third. 9+21 is greater than 13. 21+13 is greater than 9. 13 is the only number which if you add 9 to it it will be greater than 21. 12 will equal 21, but it still wont work.

hope this helps :))

Simplify 6-2(x-4)=22

taurus [48]

Assuming there 6-2 isn't in brackets, otherwise, it would be a tad more complex:

6 -2(x-4) = 22
6 -2x + 8 = 22
14 - 2x = 22
-2x = 8
-x = 4
x = -4
