Answer:
A = 9 sq. meters
Step-by-step explanation:
From the graph, we can tell that it is a isosceles triange. So,
Answer:
3ab
-------------------
(b+a)
Step-by-step explanation:
3/a - 3/b
-------------------
1/a^2 - 1/b^2
Multiply the top and bottom by a^2 b^2/ a^2/b^2 to clear the fractions
(3/a - 3/b) a^2 b^2
-------------------
(1/a^2 - 1/b^2) a^2b^2
3ab^2 - 3 a^2 b
-------------------
b^2 - a^2
Factor out 3ab on the top
3ab( b-a)
-------------------
b^2 - a^2
The bottom is the difference of squares
3ab( b-a)
-------------------
(b-a) (b+a)
Cancel like terms from the top and bottom
3ab
-------------------
(b+a)

Step-by-step explanation:
Answer:
X-int: (2,0) , (-5,0)
Y-int: (0,-10)
Step-by-step explanation:
To solve for the x-int, set y to 0.
0= x^2 + 3x - 10
0= (x-2)(x+5)
x= 2, and -5
To solve for the y-int, set x to 0.
y= (0)^2 + 3(0) - 10
y= -10
