Answer:
The dimensions of the inside rectangle are
Step-by-step explanation:
we know that
The area of the shaded region is equal to the area of the outside rectangle minus the area of the inside rectangle
see the attached figure to better understand the problem
so
using a graphing calculator
the solution is
see the attached figure
Find the dimensions of the inside rectangle
I’m pretty sure that it’s C, because you distribute the 2 that makes it 2(10)+2x-8, then you multiply 2 by 10 and get 20+2x-8, combine like terms so 20-8=12 that leaves you with 2x+12.
Hi there! :)
Answer:
x = 1/2 or -7.
Step-by-step explanation:
(I'm assuming the expression is 2x² + 13x - 7 = 0)
Factor the equation to solve for the possible values of "x":
2x² + 13x - 7 = 0
When factored, we get:
(2x - 1) ( x + 7) = 0
Use the Zero-Product property to solve for the roots:
2x - 1 = 0
2x = 1
x = 1/2.
-----------
x + 7 = 0
x = -7.
Therefore, possible values of x are x = -1/2, 7.
The total area that the cellphone will have service while at that location to the nearest million square feet is 13, 000, 000 square feet.

How to calculate the area?</h3>
Note that the shape is an isosceles triangle and θ = 45° for that side of the triangle
Using the formula:
Area = 1/2 base× height
base = 6000ft
To find the height use;
Sin θ = opposite/ hypotenuse
Sin 45 = height/ 5050
Find the value of sin 45 and substitute to the equation
0. 8509 = height/ 5050
Height = 0. 8509 × 5050
Height = 4297. 06 feet
Area = 0.5 × 6000 × 4297. 06
Area = 12, 892, 800 square feet
Area = 13, 000, 000 square feet.
Thus, the total area that the cellphone will have service while at that location is 13, 000, 000 square feet.
