Answer:

7x + 33

Step-by-step explanation:

Distribute the multiplication in the last term: 5(x + 6) becomes 5x + 30. Then, 2x + 3 + 5(x+ 6) becomes 2x + 3 + 5x + 30. 2x and 5x are 'like terms' and add up to 7x; 3 and 30 are also like terms of a different type (constants) and add up to 33.

Thus we have the equivalent, simpler expression 7x + 33.

Kyle has a storage box that is 2 ft. Long, 3 ft. High, and has a volume of 12 ft. 3 12 ft.3. Myla has a storage box that is 4 ft

Alex17521 [72]

Answer: The widths of Kyle and Myla's boxes is the same as 2 ft.

Step-by-step explanation:

Formula : Volume of cuboidal box = length x width x height

$width=\dfrac{Volume}{length\times height}$

Given: Kyle has a storage box that is 2 ft. Long, 3 ft. High, and has a volume of 12 ft³ .

$width=\dfrac{12}{2\times3}=2\ ft.$

Myla has a storage box that is 4 ft. High, 2 ft. Long, and has a volume of 16 ft³.

$width=\dfrac{16}{4\times2}=2\ ft.$

Hence, the widths of Kyle and Myla's boxes is the same as 2 ft.

$y - 3x = 13$

Add sides 3x

$y - 3x + 3x = 13 + 3x$

$y = 13 + 3x$

$y = 3x + 13$

It says: Find the surface area of the rectangular prism with l=16 m, w=19 m, annd h = 2 m

ratelena [41]

The surface area of a rectangular prism needs an formula.
For a rectangular prism you have to understand some about the shape.
It is a 3D shape consisting of 6 sides
all are rectangles
to determine the area of one rectangle is the base multiplied by the height or in this case length times with.
but you also need to account for all sides and the height.
so the Surface area formula would be like
$sa = l \times w + l \times h + w \times h$
this accounts for 3 of the sides of the rectangular prism.
the top,bottom,and side.
so to get the surface area of a rectangle prism you must mutiply each side by 2 to account for all sides of the rectangular prism.
so the surface area formula for a rectangular prism is
$SA = 2\\ \times l \times w +2 \times l \times h+2 \times h \times w$
I won't solve it for you but just plug in your values for l,w,and h into that formula and you will get your answer in metres squared or m
${m}^{2}$

The length of a rectangular garden is 7x + 3 feet. The width of the garden is 6x – 3 feet. Which expression represents the area

iren [92.7K]

Answer:

42x² - 3x - 9

the area of the garden is:

(7x + 3)(6x - 3)

= 42x² - 21x + 18x - 9

= 42x² - 3x - 9
