Step 1:
x² + 4x = 192
Step 2:
Take x common:
x ( x + 4) = 192
Length is x and width is x+4
Step 3:
x² + 4x - 192 = 0
Step 4:
x² + 16x - 12x - 192 = 0
x(x+16) - 12(x+16) = 0
(x-12)(x+16) = 0
⇒ x=12, x=-16
Because the length can't be -16, the length is 12.
Answer:
17.03 units
Step-by-step explanation:
The distance formula for the distance between two points (x1, y1) and (x2, y2) is ...
d = √((x2 -x1)^2 +(y2 -y1)^2)
For the given points, the distance is ...
d = √((8-(-3))^2 +(-6-7)^2) = √(11^2 +(-13)^2)
d = √(121 +169) = √290
d ≈ 17.03
The distance between the points is about 17.03 units.
Answer:
yellow 9/25
yellow and green is 14/25
Answer:
it's not a right triangle
Step-by-step explanation:
5² + 13² = 14²
=> 25 + 169 = 196
=> 194 ≠ 196
