Elina [12.6K]
1 ft equals 12 in. So 2ft equals 24 in. 24 in plus 5 in equals 29 in, and 29 in plus 9 in equals 38 in. 38/12 equals 3 ft 2 in.

Which algebraic expression represents the phrase “two times the quantity of a number minus 12”?
Yakvenalex [24]

Answer:

The algebraic expression which represents the phrase “two times the quantity of a number minus 12” is : 2x- 12

Step-by-step explanation:

Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.

for example :-

3x + 4y – 7,  4x – 10, etc.

These expressions are represented with the help of unknown variables, constants and coefficients. The combination of these three (as terms) is said to be an expression. It is to be noted that, unlike the algebraic equation, an algebraic expression has no sides or equal to sign

let the quantity mentioned in the question be 'x'

therefore according to the statement the algebraic expression which represents the phrase “two times the quantity of a number minus 12” is : 2x- 12 is

⇒2x - 12 (answer)

Explanation:

7^8/7y = 7^6
7^7/y = 7^6
In order for 7^7 to become 7^6 you need to divide by 7

Which mean y = 7

So that:
7^7/7= 7^6
7^6 = 7^6

The area of a rectangle is square units. Factor this expression. Given your answer in part A, describe what you can conclude abo
Brrunno [24]

Answer:

The factored area of the rectangle=2(2w-5)

Area of a rectangle=length×width

Step-by-step explanation:

Area of rectangle is 4w - 10 square units

We have to factor the expression

Area of rectangle = 4w - 10

common factor=2

Area of rectangle = 2(2w - 5)

Thus the given expression is factored

Area of a rectangle=length × width

Area of the rectangle=2×(2w-5)

Thus, it is safe to say

The length=2 or (2w-5)

The width=(2w-5) or 2
