Answer:
Step-by-step explanation:
The question is incomplete. Here is the complete question.
In a square ABCD, if AB = (3x-8) and BC = (x+12), find the value of x. Also, find the length of each side of the square.
Note that all sides of a square are equal. Hence AB = BC for the square ABCD.
Given AB = (3x-8) and BC = (x+12), then AB = BC
3x-8 = x+12
collect like terms;
3x-x = 12+8
2x = 20
x = 20/2
x = 10
Substitute x = 10 into any of the side. Using side AB
AB = 3x-8
AB = 3(10)-8
AB = 30-8
AB = 22
BC = x+12
BC = 10+12
BC = 22
<em>Hence x = 10 and the length of each side is 22</em>
Step-by-step explanation:
we are given a equation
we want to figure out x
add 10 to both sides:
square root both sides:
remember that,
by that
cancel 15 from both sides:
so
If the span is 16-ft, then the half-span is 8-ft.
Pitch = (rise) / (half-span) = 6/8 = 3/4 or 0.75 or 75% .
That's a VERY steep roof !
Answer:
5 adults
Step-by-step explanation:
So 4 adults are taken for 32 children. We can use 32 divided by 4 to see how many children it takes to assign an adult. the answer to this would be 8. if 8 more children are added ( which would make 32+8 which is 40) than another adult would be needed.
