Perimeter = 2L + 2W (where L = length and W = width)
And we are given that L = 3W
So substituting for L, we have the equation:-
2(3W) + 2W = 64
6W + 2W = 64
8W = 64
W = 8 meters
So the length = 3*8 = 24 meters
Answer:- Length = 24 m and Width = 8 m.
-1(7+4b) - distribute the -1 to the expression
(-1 * 7) + (-1 * 4b) — ( + and - = - )when it is multiplied
= -7 - 4b — there is no like term to added to subtracted so it will stay as like
x(x^2 - 2xy+y^2) distribute x to all
= x(x^2) - x(2xy) + x(y^2)
= x^3 - 2x^2y + xy^2 in multiplication exponent add to similar variable
No like term to connect
-5x(-3+x)
= -5x(-3) -5x(+x). (- and - is +)
= 15x -5x. similar variable x so connect the like connect like term by subtracting them
= 10x
I'm not sure how to write the rule, but every time you add one more to the sum of the last two. First, you add 1, then 2, then 3. 1+1=2 2+2=4 4+3=7 7+4=11 and so on. I hope this helps!
Total number = 30
1/5 of 30 = 1/5 x 30 = 6
The attached figures show the total number of filled
circles in five lines. Each line have “6” filled circles.
So 5 lines having 6 filled circles = 5 x 6 = 30
<span>Every line represents “1/5” of total amount “30”. Which
proved that 1/5 of 30 is equal to 6. </span>
