Answer:
158 in²
Step-by-step explanation:
<u>Surface area</u>
A = 2·(l·w + l·h + w·h)
= 2·(3in·8in + 8in·5in + 3in·5in)
= 2·(24in² + 40in² + 15in²)
= 2·(79in²)
= 158 in²

Equation = a² + b² = c²
a = 80
b = 39
c = Diagonal
a² + b² = c²
80² + 39² = c²
6400 + 1521 = c²
c² = 7921
c = √7921
c = 89
Answer = 89 units
Answer:
Step-by-step explanation:
we have to divide the given distance by 3.
Then we will be able to find the distance between markers.
Given distance is
Since, there are three markers,
So, we have to divide this distance by 3
So, the distance between markers is-
So, the distance between marker is
Now, we have to convert this into mixed number.
Then, the distance is-
3(x+4)=1/2x-8 that's your original equation. If you read through the problem as you look at my work, you will see it matches up as you read it out loud and see my equation.
to solve, first distribute.
3x+12=1/2x-8
next you need to subtract 1/2x from both sides. this is using the identity property of addition.
2.5x+12=-8
next, subtract 12 from both sides. this demonstrates the identity property of subtraction.
2.5x=-20
next, divide by the coefficient of x (which is 2.5) to find the value of x, your variable.
x=8. you're done. hope this helped :)
