Answer:
x²-10x=area
Step-by-step explanation:
Area= length×width
Length: x
Width: x-10
Area= x(x-10)= x²-10x

Answer:
98 ft²
Step-by-step explanation:
There are a couple of ways you can think about this one. Perhaps easiest is to treat it as a square with a triangle cut out of it. The cutout triangle has a base (across the top) of 14 ft and a height of 14 ft, so its area is ...
A = (1/2)(14 ft)(14 ft) = 98 ft²
Of course the area of the square from which it is cut is ...
A = (14 ft)² = 196 ft²
So, the net area of the two triangles shown is ...
A = (196 ft²) - (98 ft²) = 98 ft²
_____
Another way to work this problem is to attack it directly. Let the base of the left triangle be x. Then the base of the right triangle is 14-x, and their total area is ...
A = A1 + A2 = (1/2)(x ft)(14 ft) + (1/2)((14-x) ft)(14 ft)
We can factor out 7 ft to get ...
A = (7 ft)(x ft + (14 -x) ft)
A = (7 ft)(14 ft) = 98 ft²

5(2)+5(7)
Step-by-step explanation:
The equation that models the situation is 15x + 9y = 450
The x-intercept is (30, 0) and the y-intercept is (0, 50)
Given the following parameters:
- Cost of concert tickets for general admission= $15
- Cost of a ticket for those with student ID = $9
Given that the total sales is $450, the equation that models this situation will be expressed as:
where:
x is the those that admitted generally
y are those with student ID
<u />
<u>Get the x-intercept.</u>
This is a point where the y-axis is zero
15x + 9y = 450
15x + 9(0) = 450
15x = 450
x = 450/15
x = 30
Thee x-intercept is (30, 0)
<u>Get the y-intercept.</u>
This is a point where the x-axis is zero
15(0) + 9y = 450
0 + 9y = 450
9y = 450
y = 450/9
x = 50
The y-intercept is (0, 50)
