Answer:

The answer is 57.

Step-by-step explanation:

{\tt{\underline{\underline{\pink{SOLUTION:}}}}}

To solve the above equation we will follow the BODMAS rule.

  • \blue\star BODMAS is an order of mathematic operations.
  • \blue\star BODMAS rule is to be followed while solving expressions in mathematics.

It stands for :

  • \purple\star B = bracket
  • \purple\star O = order of power
  • \purple\star D = division
  • \purple\star M = multiplication
  • \purple\star A = addition
  • \purple\star S = subtraction

Solving this question by bodmas rule :

\begin{gathered}\qquad{\sf{ = 9 + 6( {2}^{2}  + 4)}}\\\\\qquad{\sf{ = 9 + 6(2 \times 2  + 4)}}\\\\\qquad{\sf{ = 9 + 6(4 + 4)}}\\\\\qquad{\sf{ = 9 + 6(8)}}\\\\\qquad{\sf{ = 9 + 6 \times 8}}\\\\\qquad{\sf{ = 9 + 48}}\\\\\qquad{\sf{ = 57}}\end{gathered}

Hence, the answer is 57.

(Score for Question 3: ___ of 5 points) The measure of ∠2=8x+10 and the measure of ∠4=42+6x. Find the measure of ∠4. Show your w
Svetradugi [14.3K]

Answer:

∠4 = 78°, assuming out measurements have been taken in degrees.

Step-by-step explanation:

If ∠2 = 8x + 10 and

∠4 = 42 + 6x

We will assume that x in both cases is represented by the same number, therefore, we will first need to solve for x. We will do so by equating both angle measurement expressions.

8x + 10 = 42 + 6x        Take away 6x from both sides

2x + 10 = 42                Take 10 away from both sides to combine like terms

2x = 32                        Divide both sides by 2 to isolate x

x = 16

Knowing x, we can solve for the measure of ∠4 by plugging in 16 for x

∠4 = 42 + 6x

∠4 = 42 + 6(6)

∠4 = 42 + 36

∠4 = 78°, assuming out measurements have been taken in degrees.

The top and bottom margins of a poster are each 6 cm and the side margins are each 4 cm. If the area of printed material on the
sweet-ann [11.9K]

Answer:

  24 cm wide by 36 cm high

Step-by-step explanation:

The poster with the smallest area will have an aspect ratio that makes the margin dimensions the same percentage of overall dimension in each direction.

Since the ratio of margin widths is 6:4 = 3:2, the poster and printed area will have an aspect ratio of 3:2. That is, the width is ...

  width of printed area = √(2/3·384 cm²) = 16 cm

Then the width of the poster is ...

  width = left margin + printed width + right margin = 4cm + 16 cm + 4 cm

  width = 24 cm

The height is 3/2 times that, or 36 cm.

The smallest poster with the required dimensions is 24 cm wide by 36 cm tall.

_____

If you need to see the calculus problem, consider the printed area width to be x. Then the printed height is 384/x and the overall dimensions are ...

  (x + 8) by (384/x + 12)

We want to minimize the area, which is the product of these dimensions:

  a = (x +8)(384/x +12) = 384 +12x +3072/x +96

  a = 12x + 3072/x +480

This is a minimum where its derivative is zero.

  a' = 12 -3072/x^2 = 0

  a' = 1 -256/x^2 = 0 . . . . . . divide by 12; true when x^2 = 256

This has solutions x=±16, of which the only useful solution is x=16.
