Answer:
989 ft.
Step-by-step explanation:
7*13=91
<u>91</u> is the first rectangles area.
13+6=19
19*17=323
<u>323</u> is the second rectangles area.
25*23=575
<u>575</u> is the third rectangles area.
575+323+91=989

The nature of the roots can be determined by the determinant of the equation. The determinant is:
b² - 4ac
If this is positive, there are two roots
If this is 0, there is only one root
If this is negative, there are complex roots
Answer:
y = - 5x
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = - 10 when x = 2, thus
k = = = - 5
y = - 5x ← equation of variation
