Answer:
<h2>
2(w)+2(3w-2), or, 8w-4</h2>
Step-by-step explanation:
The formula for finding the perimeter is 2w+2L (2*width + 2*length)
So, since we know the width is "w" and the length is "3w-2", we can just substitute those into the equation.
2(w)+2(3w-2)
From there, if needed, you can simplify to:
2w + 6w-4
Add like terms:
8w - 4

Answer:
52.5 kg ANS
Step-by-step explanation:
Weight of a pile of sand = 90kg
Ratio of weight of sand in three bags = 2:3:7
Let the weight be 2x kg, 3x kg, 7x kg respectively A.T.Q.
= 2x + 3x +7x = 90
= 12x = 90
= X= 90/12
= X = 7.5 kg
Weight of sand in medium bag =
= 3 × 7.5
= 52.5 kg ANS
I hope this answer is correct
Answer: 5√2
Let’s say A(-5,-3) and B(2,-4)
AB= sqr (xB-xA)² + (yb-yA)²
= sqr [2-(-5)]² + [-4-(-3)]²
= sqr 49 + 1
= sqr 50
AB= 5 sqr 2
(sqr=square root)
First you divide them all by 7 to see which are greater than 19
28/7=4
84/7=12
35/7=5
105/7=15
even if you add 1 to them they all are still less than 19
so select them all
hope this helps! :)
