Answer:

x = 4

Step-by-step explanation:

expand out the brackets to get   7 - 2x = 2x - 8 - 1

we can then add 2x to both sides to get        7  = 4x - 8 - 1

add 9 to both sides to get       16 = 4x

divide both sides by 4 to get     x = 4

hope that helps

  • 185 × 24 = 4440
  • 1288 × 33 = 42504
  • 6301 × 47 = 296147
  • 3440 × 75 = 285000

<h3>What is multiplication?</h3>
  • Multiplying in math is the same as adding equal groups.
  • The number of items in the group grows as we multiply.
  • Parts of a multiplication issue include the product, the two factors, and the product.
  • The factors in the multiplication problem 6 x 9 = 54 are the numbers 6 and 9, and the product is the number 54.

So, multiplication of the numbers:

  • 185 × 24 = 4440
  • 1288 × 33 = 42504
  • 6301 × 47 = 296147
  • 3440 × 75 = 285000

(Refer to the images attached below for calculations)

Therefore, the answers to all the subparts of the multiplication problem are shown:

  • 185 × 24 = 4440
  • 1288 × 33 = 42504

2. Find the area in square meters of the figure<br> below? Use 3.14 for.<br> 6m
Illusion [34]

Answer:

in order to find the area, we should break up the figure. you can see that in the image we have a quarter of a circle and a square. here are the areas for each of these shapes

square:

area = {x}^{2}

circle:

area = \pi {r}^{2}

but since we only have a quarter of this circle we need to divide the area by 4 so the formula becomes

\frac{\pi {r}^{2} }{4}

now we can plug in our numbers

we are given 6 m for our radius or length of square

the square will be (6)^2 = 36 m^2

now onto our circle

π(6)^2/4 = 28.26 m^2

now add these two shapes together to find the total area = 64.26 m^2
