Answer:
16 yards by 14 yards
Step-by-step explanation:
let w be the additional width from the walkway
The total area is then
(w + 10)(w + 8) = 224
Expand
w^2 + 18w + 80 = 224
Subtract 224 from both sides
w^2 + 18w - 144 = 0
Factor (if you can't see how this factors use the quadratic equation)
(w + 24)(w - 6) = 0
w = {-24, 6}
Disregard the -24 since width cannot be negative
w + 10 = 6 + 10 = 16
w + 8 = 6 + 8 = 14
The garden plus walkway is 16 yards by 14 yards
Answer:
if the garden is 10 by 8 that would equal 80. so you have to take 80 out of 224. it equals 144. so you have to figure out what would equal 144. 12 times 12 equals 144. so that is the dimension for the walkway.

1 3/4 - a<3/4
proof:
1 3/4 -a<3/4
=>1 3/4 - 1 3/4 -a<3/4- 1 3/4
=>-a<-1
=>a>1
Answer:
m = - 1/4
Step-by-step explanation:
When two line is perpendicular to each other the product of them is - 1
So let the other line be B
Gradient of B = t
Gradient of A = 4
therefore m = - 1/4
