Step-by-step explanation:
Start with the given
Divide the two on both sides to get
Answer:
(1,2)
y=2
x=1
Step-by-step explanation:
x+y=3
3x+5y=13
solve the equation
x=3-y
3x+5y=13
substitute the value of x into an equation
3(3-y)+5y=13
distribute
9-3y+5y=13
add -3y to 5y
9+2y=13
subtract 9 from both sides
2y=4
divide both sides by 2
y=2
substitute the value of y into an equation
x=3-2
subtract 3 to 2
x=1

SA = 2<span>(<span><span><span>wl</span>+<span>hl</span></span>+<span>hw</span></span><span>)
Plug in what we know:
SA = </span></span>2<span>((24)(27)<span>+(38)(27)+(38)(24)</span><span>)
Multiply:
SA = 2(648 + 1026 + 912)
Add:
SA = 2(2586)
Multiply:
SA = </span></span>5172
The answer is 360 because LxWxH
