Answer:
x=6
Step-by-step explanation:
2(3x+4)=5x+3x-4
combine all like terms and distribute
6x+8=8x-4
-8 -8
6x= 8x-12
-8x -8x
-2x= -12
x= 6
Good evening Brian,
For this problem, let's look at what we're given. So we have a pool with a length that is 13 m (meters) longer than its width, and we're given the perimeter, or distance around the entire pool, which is 74 m.
We know that the pool has a rectangular shape and that the perimeter of a rectangle is <span>width + length + width + length ⇒ 2(W) + 2(L)</span>.
Given the information provided, we can rewrite the equation to fit this problem. Since we're told that the length is equal to 13 m + the width, so we can represent the length as W +13 m. We can now rewrite the perimeter equation to be:
2(w) + 2 (w + 13 m) ⇒ 2(w) + 2(w) + 2(13 m) ⇒ 4(w) + 26 m = 74 m.
We're down to one variable now so this should be easy. Subtract 26 m from both sides,
4(w) = 48 m
Now divide each side by 4 in order to find the width.
w = 12 m
-Hope this helps!

Answer:
<em>16.8 cubic centimeter</em>
Step-by-step explanation:
Dimensions of rectangular prism are:

To find:
The volume of rectangular prism in cubic cm ?
Solution:
The formula for volume of prism is given as:

Where
is the length of rectangular prism
is the width of rectangular prism
is the height of rectangular prism
Here we are given the three dimensions of prism as:
Length,
= 4 cm
Width,
= 3 cm
Height,
= 1.4 cm
Putting the values in formula for volume:

So, volume is <em>16.8 cubic centimeter</em>.
3y - x = a
To solve for y we isolate the y variable.
3y = x + a
y = (x + a)/3
