8+4=12
9+7=16
12^2=144
16^2=256
144+256=400
square root of 400 is 20
therefore the distance from (8, -7) to (-4,9) is 20.

Answer:
$1,216
Step-by-step explanation:
Costs for Handsome Homes fabric
Area (sq. ft.) Cost (dollars)
(x) (y)
250 475
500 950
750 1,420
1000 1,900
If you divide any y-value by its corresponding x-value, the quotient will be 1.9
This means that each square foot costs $1.90 at Handsome Homes
Discount Diggers = 20% per sq. ft. less than Handsome homes
Discount Diggers = $1.90 - 20%
Discount Diggers = $1.90(100 - 20%)
Discount Diggers = $1.90(0.8)
Discount Diggers = $1.52
Now that it is known how much 1 square foot of fabric costs at Discount Diggers, we need to find how much 800 square feet of fabric costs.
$1.52 = 1 sq. ft.
$1.52(800) = 800 sq. ft.
$1,216
800 square feet of landscape fabric at Discount Diggers costs $1,216
Hope this helps :)
Answer:
Quotient = -6
Remainder = -19
Step-by-step explanation:
(3*4 - 3*3 - 6x-10) / (x-2)
= (12 - 9 - 10 - 6x) / (x-2)
= (-6x -7) / (x-2)
Quotient = -6
Remainder = -19
