Answer:

4x - 20

Step-by-step explanation:

Combine like terms (those with the same amount of variables:

x + x + x + x = 4x

4x - 20 => Note: You cannot combine these two terms, because they do not have the same amount of variables (one having one variable (x), the other being a constant (no variable) ).

Length 21cm area 315cm2 find the breath

Ronch [10]

Answer:

Breadth = 15 cm

Step-by-step explanation:

Area = length x breadth

315 = 21 x breadth

$\frac{315}{21} = \frac{21}{21} \times breadth$ [ dividing both sides by 21 ]

$15 = 1 \times breadth\\\\breadth = 15 \ cm$

According to the rational root theorem, what are all the potential rational roots of f(x)=5x^3-7x+11

Genrish500 [490]

Answer:

$\pm11,\pm1,\pm\frac{11}{5},\pm\frac{1}{5}$

Step-by-step explanation:

The given polynomial function is

$f(x)=5x^3-7x+11$

According to the Rational Roots Theorem, the ratio of all factors of the constant term expressed over the factors of the leading coefficient.

The potential rational roots are

$\pm\frac{11}{1}=\pm11$
