Do you have a picture I could look at?
other leg = 12 cm
using Pythagoras' identity with x as the side to be found, then
x = √(13² - 5² ) = √(169 - 25 ) =√144 = 12
Y - y1 = m(x - x1)
slope(m) = 3/4
(-4,6)....x1 = -4 and y1 = 6
now just sub...and pay attention to ur signs
y - 6 = 3/4(x - (-4)...not done yet
y - 6 = 3/4(x + 4) <===

Step-by-step explanation:
Answer:
P = 28cm
Step-by-step explanation:
The general formula for the perimeter of a rectangle is: 'P = 2L +2W' (L being the length and W being the width of the rectangle.)
Step 1: Substitute L = 7, W = 7 into the general formula.
P = 2(7) + 2(7)
Step 2: Solve!
P = 2 x 7 + 2 x 7
P = 14 + 14
P = 28
Step 3: Don't forget to add the units of measurement! (In this case 'cm')
Therefore, P = 28cm
