Answer:
<em> 200cm²</em>
Step-by-step explanation:
Total surface area of the prism = bh + L(s1+s2+s3)
b is the base of the triangle = 15cm
h is the height of the triangle = 8cm
Perimeter of the triangular base = s1 + s2 + s3 = 8+17+15
Perimeter of the triangular base = 40cm
L is the lateral height = 2cm
Substitute the given values into the formula;
Total surface area of the prism = 15(8) + 2(40)
Total surface area of the prism = 120+80
Total surface area of the prism = 200cm²
<em>Hence the total surface area of the prism is 200cm²</em>
Simple...
you have:

and

To solve for....

Multiply to remove the denominator-->>

n=12*3
n=36
Then-->>>

Do the same thing-->>

n=-12*3
n=-36
Thus, your answer.
Answer:
A
Step-by-step explanation:
It is the first one because it you mark the number 2 between 0 and 4 and the number 5 between 0 and 10, you can see it is just in the middle which is 2:5
x= 18
let me show you the workout
6x+1+12x-5=32
Combine like terms .Combine 6x+12=18x
18x-4=32 Subtract -4 from 32
18x=36 Divide by 18 and
X=16
Hoped this helped Im not sure if this is right
