Answer: 6 horses bc you just have to multiply by 3
Answer:
Step-by-step explanation:
check the picture below, you can pretty much count the units off the grid.
recall that A = (1/2)bh.
Rearrange to: x^2 + 18x - 25 = 0
Then factorise (I like to do it by completing the square):
(x + 9)^2 -81 -25 = 0
(x + 9)^2 = 106
x + 9 = sqrt(106)
The sol'ns are:
x = -9 + and - sqrt(106)
