Step-by-step explanation:
Let x=number 1 let y=number2
there sum is equal to 70
then
number1+number2=70
substituting
x+y=70
y=70-x
let there product will be p
p=xy
substituting
p=x(70-x)
which is choice c
Answer:
The width of the garden must be 7 feet.
Step-by-step explanation:
Total amount of fencing material = 56 feet, and given that the length of the garden = 21 feet.
Since the fence would be in the shape of a rectangle, then;
perimeter of a rectangle = 2(l + w)
where l is the length and w is the width.
So that, perimeter = 56 feet, l = 21 feet.
Thus,
56 = 2(21 + w)
28 = 21 + w
w = 28 - 21
= 7
The width of the garden must be 7 feet.
