Answer:
16
Step-by-step explanation:
Simplify the following:
4 + 3×2^3/2
3×2^3/2 = (3×2^3)/2:
4 + (3×2^3)/2
Combine powers. (3×2^3)/2 = 3×2^(3 - 1):
4 + 3×2^(3 - 1)
3 - 1 = 2:
4 + 3×2^2
2^2 = 4:
4 + 3×4
3×4 = 12:
4 + 12
4 + 12 = 16:
Answer: 16
Step-by-step explanation:
your going to distribute the 2 to the x and the four your equation will then become (2x-8)=-5 you would then do the opposite of subtraction which is add so add +8 to the -8 and that cancels it out then you would +8 to the -5 and get 2x=3 then I'm confused from there hope that helps kinda
Answer:
it is an answer if you are using a coordinate plane
Step-by-step explanation:
My best answer is B) 96 square feet
Using the tree as an origin point we know the location of both corners of the rectangular garden around the tree. this can help us find the area of perimeter of this rectangle -
the rectangle is 3 feet wide and 7 feet long - However only the numbers matter here because we will use them to find the values of the path Jenny is paving which can be depicted as a 3 ft wide border along the rectangular garden.
The values are 7 + 3+ 3 = 13 (I added 3 ft to each side )
and 3 + 3 + 3 = 9 ( added 3 ft border to each side)
Now we can find the area of this new larger rectangle
13 x 9 = 117
then we subtract the area of the garden within this larger rectangle so that we may be left with only the <em>area of the path on the outside</em>
7( Length of inside rectangle) x 3 ( Width of inside rectangle) = 21 ft squared (area of inside garden)
so then the total area 117 - 21 ( internal area used for gardening)
Which gives us the final answer of B) 96 square feet
