Step-by-step explanation:
3x + 1
=3x + 1
this is because a variable X is attached to the 3 so it makes the 3x and the 1 unlike
therefore you can not add them.
Hello!
So, here you want to do the distributive property.
Start on the left side of the + sign...
-3*u = -3u
-3*3 = -9
So we now we have:
(-3u + -9) + 4(4u + 2)
Now we focus on the right side of the + sign...
4*4u=16u
4*2=8
So now we have:
(-3u + -9) + (16u + 8)
Now you want to combine like terms. Start by adding terms with the same variable. So, we need to add -3u and 16u
<em>-3u + 16u =</em> 13u
Now we have:
13u + -9 + 8
Now add the constants, -9 + 8
-9 + 8 = -1
So, the simplified expression would be:
13u - 1 or 13u + -1
This shows that the number of quarts she should you buy to stain the wheelchair ramp is 9 quart
<h3>Surface area of a pyramid</h3>
This the sum of all the area of the surfaces. The given figures is made of 3 rectangles and 2 triangles
<u>Determine the surface area</u>
TSA = (25*25) + (2 * 5*301/12) + (5*2.08333)
TSa = 625 + 258.33333 + 10.41665
TSA = 893.74995
If a quart of stain covers 100 square feet, the total nuber to buy is given as:
Number to buy = 894/100 = 8.94
This shows that the number of quarts she should you buy to stain the wheelchair ramp is 9 quart

When x = 3 z = 57 57/3 = 19
19*8 = 152
So when X is equal to 8, Z is equal to 152.
