WILL GIVE BRAINLIEST<br><br><br> Write 2/7x(1.4x^2-3.5y) as a polynomial
olya-2409 [2.1K]

The expression (2/7)x (1.4x² - 3.5y) can be written in the form of a polynomial as 0.4x³ - xy.

<h3>What is polynomial?</h3>

Polynomial is an algebraic expression that consists of variables and coefficients. Variables are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.

The expression is given below

\rm \dfrac{2x}{7} \times (1.4x^2-3.5y)

The expression can be written in the form of the polynomial

\rightarrow \rm \dfrac{2x}{7} \times (1.4x^2-3.5y)\\\\\\\rightarrow \rm \dfrac{2x \times 1.4x^2}{7} - \dfrac{3.5y\times 2x}{7 }\\\\\\\rightarrow \dfrac{2.8x^3}{7} - \dfrac{7xy}{7 }\\\\\\\rightarrow 0.4x^3 - xy

The expression in the form of a polynomial is given as

\rm \rightarrow 0.4x^3 - xy

More about the polynomial link is given below.

What is m Please help me
8090 [49]

Answer:

Angle BCA = 70

Angle CAB = 20

Step-by-step explanation:

Not sure what angle you meant, so I'll give you all of them <3

Angle BCA = 70 degrees, because If two angles form a line, they add up to 180.  (110+x=180, x = 70)

Angle CAB = 20 degrees, because there are 180 degrees in a triangle, so 90+70+x=180, x = 20

Hope it helps <3
