Answer:
A = 10W - W²
Step-by-step explanation:
Perimeter of a rectangle = 2(L+W)
Area of a rectangle =LW
L is the length
W is the width
Given
Perimeter = 20m
20 = 2 (L+W)
10 = L+W
L = 10 - W ....2
Substitute equation 2 into the formula for calculating the area
Recall that A = LW
A = (10-W)W
A = 10W - W²
Hence the area of the rectangle as a function of the length of ones its side is expressed as A = 10W - W²
The answer is w = 12 hope this helped:)
Combine like terms so 3x + 3x= 6x
Then put the minus signs with the 4 and 5 and add them together so -4+ -5= -9
Now you have 6x=-9 So you divide by 6 on both sides canceling out 6
but 9 divided by 6 doesn't go into a specific number therefore it has no solution which is a possible answer
3.93 (million) + (5.31 million). y (3.91 M) + y (oth) = 1.
So in distributive property you multiply the outside number by the two inside so in this case 2(a) + 2(-2) = 3(a) + 3(-5)
Which will give you
2a+ - 4 = 3a + - 15
Or
2a-4=3a-15
Then if your solving for a your can subtract 3a from 2a giving you
- a-4=-15
Then add 4 to - 15
-a =-11
Then divide by negative 1 (this is so a isn't negative)
A=11
Hope this helps!
