Let length = l , width = b
Perimeter = 2 (l +b)
46= 2 (l +b)
(l + b) = 23
l*b = 120
So l + 120/l = 23
l^2 + 120 - 23l = 0
l^2 -15l + 8l + 120 = 0
(l-8) (l - 15) =
l = 8 or 15
i.e if l =8, w=15
and if l = 15, w = 8
Answer:
V-20
Step-by-step explanation:
(-2) + (-18)= -20
Answer:
790
Step-by-step explanation:
The volume equals: Height * Width * Length
Therefore, the volume = 22.9*7.5*4.6 = 790 cubic meters.
We can set up a proportion here. On map scales, the scale goes like:
“1 (length on the map) : x (real life length)”
Here, we have 2 : 8. We need to make it so the first number is 1, because thats easier for measuring.
2 : 8 /divide both sides by 2
1 : 4
The scale would be 1in : 4mi (in other words, 1 inch on the map corresponds to 4 miles in real life).
Answer:
y = 46
Step-by-step explanation:
I'm assuming you wanted to solve for y.
x = 5
y = 8(5) + 6
y = 40 +6
y = 46
