Answer:
Slope = -1
Step-by-step explanation:
Hope it helps you.......
Step-by-step explanation:
2×length + 2×width = 45
length = 4×width
now, we are using the second equation (a variable identity) in the first equation
2×4×width + 2×width = 45
8×width + 2×width = 45
10×width = 45
width = 45/10 = 4.5 in
length = 4×width = 4×4.5 = 18 in
the area of the rectangle is
length × width = 18 × 4.5 = 81 in²
Answer:
17i
Step-by-step explanation:
d= (under radical sign) (x2-x1)^2 + (y2-y1)^2
plug in the numbers and simplify and youll get (again under the radical sign) (-8)^2 + (-15)^2
do the math again and youll get -289 under the radical. square root of 289 is 17 and you add the i next to it because it is negative and those numbers aren't real
