6 0

Answer: <em>уравнение имеет 2 решения:</em>

<em>               x₁ = - 4;    x₂ = - 2.</em>

Step-by-step explanation:

<em>Ix + 3I = 1</em>

<em>1) x + 3 = 1</em>

<em>   x + 3 - 3 = 1 - 3</em>

<em>   x = -2</em>

<em>2) - (x + 3) = 1</em>

<em>    x + 3 = - 1</em>

<em>    x + 3 - 3 = - 1 - 3</em>

<em>    x = - 4</em>

The length of a rectangle is six times its width. If the perimeter of the rectangle is 98 yd , find its area.
kumpel [21]
P=2(W + L)
p= 2W + 2L
98=2W + 2(6W)
98=2W + 12W
98=W
98/14=14W/14
W=7

L= 6W
L = 6(7)
L= 42

CHECK
p=2(7 +42)
p=2(49)
p= 98

Area of a rectangle = W X L
Area of a rectangle = 7 X 42
Area of a rectangle = 294
