Multiplying binomials (×+2) (×-9)

musickatia [10]

Answer:

x² -7x -18

Step-by-step explanation:

In algebra, a binomial consists solely of a sum or subtraction of two monomials.

To solve the multiplication of two binomials we have to multiply term by term and then simplify common terms.

(x + 2)(x - 9) = x(x) + x(-9) +2(x) + 2(-9) = x² -9x + 2x -18 = x² -7x - 18

11) Specific resistance is also called ? and is abbreviated with the capital letter K or the Greek letter ρ (rho).

Nuetrik [128]

Answer:

Resistivity

Step-by-step explanation:

Resistivity : It is a fundamental property of a material that measures how strongly a particular material opposes the flow of electric current. It is also known as specific resistance.

A low resistivity indicates a material that easily allows the flow of electric current.

Resistivity is commonly represented by the Greek letter ρ (rho) or abbreviated with a a capital letter K. The SI unit of electrical resistivity is the ohm-metre (Ω⋅m).

Hence, the correct answer for the blank is Resistivity.

Sum : $(5 x+1)$

Term : 1, $5x$ and $3y$

Product : $9(5x+1),5x$ and $3y$

Factor : 5 and x, 3 and y, 9 and 5x+1

Quotient : $\frac{9(5x+1)}{3y}$

Coefficient : 5 is the coefficient of x and 3 is the coefficient of y.

Explanation:

The expression is $\frac{9(5x+1)}{3y}$

Sum: Sum is the result of addition of terms.

Thus, from the expression,

Sum = $(5 x+1)$

Term : A term is a single number or a variable or a number multiplied with a variable.

Thus, from the expression,

Term = 1, $5x$ and $3y$

Product : Product is the result of multiplication of numbers.

Thus, from the expression,

Product = $9(5x+1),5x$ and $3y$

Factor : The numbers that are multiplied is called a factor.

Thus, from the expression,

Factor = 5 and x, 3 and y, 9 and 5x+1

Quotient : Quotient is the result of dividing two numbers or variables.

Thus, the given whole expression is a quotient.

Hence, Quotient = $\frac{9(5x+1)}{3y}$

Coefficient : Coefficient of a variable is a number multiplied with a variable.

Thus, from the expression,

Coefficient : 5 is the coefficient of x and 3 is the coefficient of y.

You and your friend each start a car-washing service. you spend $25 on supplies and charge $10 per car. your friend spends $55 o

lakkis [162]

Let x be the number of cars. We will find out how many cars you have to wash to make as much money as your friend:
10x - 25= 13x - 55 Add 25 on both sides and subtract 13x, also both sides:
3x = -30 Now divide both sides by -3:
x= 10 cars you have to wash.
