Step-by-step explanation:
Apply Rational Root Thereom:
If we have a polynomial, P(x), the possible roots of the polynomial are the factors of the constant divided by the factors of the leading coeffceint.
Our constant is 10 and our leading coefficient is 2 so our possible factors are (the factors are positive and negative).
10:1,2,5,10
2:1,2
So our possible roots are
Remeber to include the plus and minus sign.

<h3>RESPUESTA</h3><h3>la recta numérica también puede medirse en centímetros</h3>
X=area of Sahara.
y=area of the Gobi Desert.
We suggest this system equations:
x+y=4000000
x=7y
solve by susbstitution method.
(7y)+y=4,000,000
8y=4,000,000
y=4,000,000 / 8=500,000
x=7y
x=7(500,000)=3,500,000
The area of Sahara=3,500,00 miles².
The area of the Gobi Desert=500,000 miles²
To check:
Te sum of their areas is : 3,500,000 miles²+500,000 miles²=4,000,000 miles²
Te area of sahara (3,500,000 miles²) is 7 times the area of the Gobi Desert (7*500,000 miles²=3,500,000 miles²).
