Answer:
width = 4.5 m
length = 14 m
Step-by-step explanation:
okay so first you right down that L = 5 + 2w
then as you know that Area = length * width so you replace the length with 5 + 2w
so it's A = (5 +2w) * w = 63
then 2 w^2 + 5w - 63 =0
so we solve for w which equals 4.5 after that you solve for length : 5+ 2*4.5 = 14
Answer:
12,500 liters
Step-by-step explanation:
Given that
One cubic meter = 1000 liters
One cubic decimeter = 1 liter
We need to find out the number of liters fit in a 12.5 cubic meter
So
As it is mentioned that
One cubic meter = 1000 liters
So for 12.5 cubic meter
The number of liters would be
= 1000 × 12.5
= 12,500 liters
I would say it equals 4 because if x=-4 than -x should equal 4 i may be wrong though
Hello,
Let's assume a the hypotenuse
b/a=sin 30°==>b=a/2
c/a=cos 30°==>c=√3 / 2 *a
(√3/2 a, a/2,a) are the sides of the triangle.
