Answer and Step-by-step explanation:
You got the triangle at front, half of 6 is 3, so then you do 4 times 3 divided by 2, which is 6.
There are 4 of those triangles, so 4 times 6 is 24.
Now, we got two rectangles on top. 5 times 12 is 60, and 60 + 60 is 120.
the bottom rectangle is 6 times 12, which is 72.
Now we add.
24 + 120 + 72 is 216
<u>216 </u>

Answer:
an=12−1.5n
Step-by-step explanation:
The first term is 10.5.
The common difference is ...
9 - 10.5 = -1.5
The n-th term can be described by ...
an = a1 +d(n -1)
an = 10.5 -1.5(n -1) = 10.5 -1.5n +1.5 . . . . eliminate parentheses
an = 12 -1.5n
Objective: Solve 3y - 20 = 8y for y.
Step 1: Collect the y-terms.
To collect the y-terms, you'll need to subtract 3y from both sides.
3y - 20 - 3y = 8y - 3y
-20 = 5y
Step 2: Isolate y.
Now that there is only one variable term, you must isolate the variable by dividing the term by the coefficient of the variable.
-20 ÷ 5 = 5y ÷ 5
-4 = y
Answer:
y = -4
