Answer:
A and B
16 times 13=208
18 times 18=324
Subtract those and you get 116
Answer:
Step-by-step explanation:
x^3+3x^2+5x+3 divided by x+1
x^2+2x+3
Let the two numbers be x and y
(x+y)-18=2x
x+y-18=2x
x+y-2x=18
-x+y=18_______(1)
(x-y) -32=2y
x-y-32=2y
x-y-2y=32
x-3y=32_______(2)
from eqn (1) y=18+x____(3)
substitute eqn (3) into eqn(2)
x-3{18+x} = 32
x-54-3x=32
-2x=32+54
-2x = 86
x= -43
sub x=-43 into eqn (3)
y=18+(-43) = 18-43 = -25
Answer:
The approximate length of the garden is at least 22 feet and at most 51 feet.
Step-by-step explanation:
A rectangular garden must have a perimeter of 145 feet.
Let x feet be the lengths of the garden. Then the width of the garden can be found using the perimeter:
The area of the garden is
The area must be at least 1,100 square feet, then
Solve this quadratic inequality:
