The long division below shows the first term of the quotient. which polynomial should be subtracted from the dividend first? x 2
Doss [256]

The polynomial to be subtracted is derived from the multiplication of the first term of the quotient and is given as: x³ + 2x²

<h3>What are polynomials?</h3>

Polynomials are mathematical expressions consisting of variables, constants and exponents, which are combined using mathematical operations such as addition, subtraction, multiplication and division.

The long division is as follows:

(x³ + 3x² + x) ÷ x + 2

The first quotient will be x².

Multiplying (x + 2) and x² gives the polynomial to be subtracted from the dividend.

(x + 2)×(x²) = x³ + 2x²

Therefore, the polynomial to be subtracted is x³ + 2x².

The value of y varies directly with x, and y= -10 when x=40. Identify the value of y when x=-5
scoray [572]

Answer:

y = 1.25

Step-by-step explanation:

Use the direct variation equation y = kx, and solve for k:

y = kx

-10 = k(40)

-0.25 = k

So, the equation is y = -0.25x. Solve for y when x = -5

y = -0.25x

y = -0.25(-5)

y = 1.25

So, y = 1.25 when x = -5

What is 1 3/5 × 2 1/7​
MakcuM [25]

Answer:

\large\boxed{1\dfrac{3}{5}\times2\dfrac{1}{7}=3\dfrac{3}{7}}

Step-by-step explanation:

Step 1:

Convert the mixed numbers to the improper fractions:

1\dfrac{3}{5}=\dfrac{1\cdot5+3}{5}=\dfrac{8}{5}\\\\2\dfrac{1}{7}=\dfrac{2\cdot7+1}{7}=\dfrac{15}{7}

Step 2:

We multiply the numbers remembering about simplifying:

1\dfrac{3}{5}\times2\dfrac{1}{7}=\dfrac{8}{5\!\!\!\!\diagup_1}\times\dfrac{15\!\!\!\!\!\diagup^3}{7}=\dfrac{8\times3}{1\times7}=\dfrac{24}{7}=\dfrac{21+3}{7}=\dfrac{21}{7}+\dfrac{3}{7}=3\dfrac{3}{7}
