Please write this polynomial as P(x) = <span>-2x^4+24x^2-10, using " ^ " to denote exponentiation.
This is a fourth degree polynomial, since the highest power of x is 4. Ordinarily, a fourth degree poly would have 5 terms, but here two of the coefficients of the powers of x are zero, leaving only 3 terms.
</span>The lead coeff. of P(x) = -2x^4+24x^2-10 is -2.
The constant terms is -10. The exponent of x here is zero (0).
The degree of the middle term is 2 (see 24x^2, above)
Would you please post your other questions separately. Thank you.
Answer:
1 1/4
Step-by-step explanation:

five eighths plus five eighths equals ten eighths simplified to one and two eighths and simplified again to one and one fourth.
If the triangle were to be a square, it would be 20 by 20. 20 × 20 is 400. To find the triangle divide by 2. 400 ÷ 2 = 200. The area of the triangle is 200.
When converted to a household measurement, 9 kilograms is approximately equal to a
