Simplify 3(x-4)+8(x+2) A) 11x-4 B)11x+4 C)11x-2
swat32
It is depending upon multiplication of values to variable and values of numbers again. Here the answer is Option B) 11x + 4. Here is my process on this equating expression.

For this we have to apply the law of distribution or the distributive law, in this we distribute the parentheses into the brackets to further expand them, we further eliminate the bracketed groups and perform the calculations. So, it is stating that, for any number, variable or a quantity if multiplied into a bracketed expression yields two products of multiplication of two quantities; one being the first quantity outside the brackets and two separately distinguished quantities inside the brackets. They are furthermore subtracted by the first quantity to that of the second quantity to obtain and achieve the distributive law.

If I were to express it through mathematical LaTeX Expressions, it will be represented as the first quantity as a variable of "a" where it can exhibit a value or a variable or a term or rule, etc. and then inside the brackets represented as "b" and "c".

Performing the law of distribution of values, variables, etc. It is demonstrated as:

\boxed{\mathbf{a \times (b - c) = a \times b - a \times c}}

We are given the values of the variables as a separate context and addition of two expressions. So, for both of them:

\mathbf{First \: \: Expression: \: 3 (x - 4)}

\mathbf{Second \: \: Expression: \: 8 (x + 2)}

Apply the following distribution law to expand the values onto variables and numbered values inside the brackets.

So, the variable "a", "b" and "c"; For First Expression is: a = 3, b = x and c = 4.

And, Similarly, for the variable of "a", "b" and "c", For Second Expression is: a = 8, b = x and c = 2.

Therefore, According to our distributive law of expanding the components will directly yield us:

\mathbf{3 \times x - 3 \times 4 + 8 \times x + 8 \times 2}

\mathbf{3x - 12 + 8x + 16}

Regroup the terms for a better visualisation and a clearer understanding for similarities between the terms; it makes it more easier to proceed further. So:

\mathbf{3x + 8x - 12 + 16}

All we did, was to separate the variable attached numbered values and shift it on one side; And, separating or shifting the values without variables to the other side.

\mathbf{11x - 12 + 16}

\boxed{\huge{\mathbf{Required \: \: Answer: \: 11x + 4}}}

Hope it helps.

Find the height of the a parallelogram with an area of 63 square yards and base 9 yards<br>​
den301095 [7]

Answer:

7

Step-by-step explanation:

The formula for the area of a parallelogram is the same formula to get the area of a rectangle. In a rectangle, the height is the area divided by base. Therefore, the height of the parallelogram would simply be the area divided by base.

three boards are placed end to end to make a walkway. the first board is 4 feet 5 inches long, the second is 6 feet 9 inches lin
AysviL [449]

Answer:

15 feet 1 inch

Step-by-step explanation:

Given :

Length of boards placed end to end :

Board 1 = 4 feet 5 inches

Board 2 = 6 feets 9 inches

Board 3 = 3 feets 11 inches

The length is the addition of the lengths of the 3 boards :

4 ft 5in + 6 ft 9 in + 3 ft 11 in

(4+6+3) ft + (5+9+11) in

13ft + (25in)

1 ft = 12 in

25 in = 2 ft 1 in

13 ft + 2ft 1 in

15 ft 1 in

a family of five pick apple trees. Two can pick 1.5 bushels per hour. Three can pick 2.3 bushels per hour. How many bushels does
Step2247 [10]

Answer:   79.2 bushels

<u>Step-by-step explanation:</u>

Total for 1 hour is: 2(1.5 bushels) + 3(2.3 bushels)

                            =   3 bushels    +   6.9 bushels

                            =              9.9 bushels


Total for 8 hours is: 9.9 × 8

                               = 79.2
