In Polynomials all the exponents of x-variable must be positive integers, then polynomials are:
a) -x^5+7x-1/2x^2+9, the exponents of x's are: 5, 1, and 2
b) x^3-4x-3, the exponents of x's are: 3, and 1
f) x^4+x^3√7+2x^2-√3/2x+π, the exponents of x's are: 4, 3, 2, and 1

Not polynomials are:
c) 4 / x^2-4x+3 = 4x^(-2)-4x+3, the exponents of x's are -2, and 1
d) x^4+5/x^3-√x+8=x^4+5x^(-3)-x^(1/2)+8, the exponents of x's are 4, -3, and 1/2
e) |x|^2+4√x-2=|x|^2+4x^(1/2)-2, the exponents of x's are 2 and 1/2

Which statement regarding the diagram is true?

dedylja [7]

Answer:

m∠KML+m∠MLK=m∠JKM

Step-by-step explanation:

we know that

The sum of the interior angles of triangle must be equal to 180 degrees

m∠KML+m∠MLK+m∠MKL=180° -----> equation A

m∠JKM+m∠MKL=180° -----> by supplementary angles (form a linear pair)

m∠MKL=180°-m∠JKM ----> equation B

substitute equation B in equation A

m∠KML+m∠MLK+(180°-m∠JKM)=180°

m∠KML+m∠MLK=m∠JKM

The area of a rectangle is 77ft and the length of the rectangle is 3ft more than double the width. Find the dimensions of the re

Radda [10]

Let b= length and a=width
Area= a*b and the problem said b=2a+3 (the length is 3ft more than double the width)
Replace b into Area formula:
Area= a*(2a+3) and we know that Area=77ft from the problem, so:
77=2a^2+3a now order and equal to zero:
2a^2+3a=77 now solve this with quadratic formula and you will get so values for a: -7ft and 5.5ft as you know the dimensions could not be negative so the correct answer for "a" side is 5.5ft, for getting the b side you haeve to replace a=5.5 into b=2a+3 and you will get b=2*5.5+3= 14ft.
Finished.
