Step-by-step explanation:

11x + 4       + 3x      + 78 = 180

14x +82 =180

x = 7

then B =   11x + 4    = 11(7) + 4 = 81 degrees

Which operation would you do second in the following problem?
sleet_krkn [62]

Answer:

C. Multiplication

Step-by-Step Explanation:

This problem is testing your knowledge of the Order of Operations. Here is the correct order:

Exponents (inside parenthesis)- There are no exponents for you to solve in this expression, so just ignore this step for now. (example: (4 + 2²) --> (4 + 4))

Parenthesis (from left to right)- In this case, you would solve the expressions inside the parenthesis <em>first</em> because there are no exponents.

Multiplication and Division (from left to right outside of parenthesis)- After solving the expressions inside the parenthesis, there will be one multiplication you need to solve next.

Addition and Subtraction (from left to right outside of parenthesis)- The only operation left for you to do now is addition. You can either do this in one whole step, or you can divide it into two steps. I've done it in two to keep it simple.

Here is the problem worked out in steps in case you are confused:

Step 1: Parenthesis

(-8 ÷ 4) + 5 + 4(3 - 6)

(-2) + 5 + 4(-3)

Step 2: Multiplication

-2 + 5 + 4(-3)

-2 + 5 + (-12)

Step 3: Addition

-2 + 5 + (-12)

3 + (-12)

-9

(Note: '3 + (-12)' could also be written as '3 - 12', making it a subtraction instead of an addition)

Hope this helps!

The area of a rectangle is found by multiplying the length by the width: A = lw. A certain rectangle has an area of x2 + 7x + 12
kupik [55]

Answer:

Option C is correct

l = x+4 unit and w = x+3 unit

Step-by-step explanation:

Area of a rectangle is given by:

A =lw           ....[1]

where

A is the area of rectangle

l is the length of a rectangle

w is the width of a rectangle.

As per the statement:

A certain rectangle has an area of x^2 + 7x + 12

⇒A = x^2+7x+12

Now factor this trinomial :

A = x^2+4x+3x+12

⇒A = x(x+4)+3(x+4)

⇒A=(x+4)(x+3) unit square

On comparing with [1] we have;

l = x+4 unit and w = x+3 unit

Therefore,the length and width of the rectangle are:

l = x+4 unit and w = x+3 unit
