Start with the given formula for the surface area of a sphere.
Now substitute 2x + 5 in for r, the radius.
Then simplify the expression and write it in standard form.
Answer:
1,3
Step-by-step explanation:
Answer:c=127.3ft
Step-by-step explanation:Divide the square into two on the line between 1st and 3rd base, you now have two right triangles, pick one. The triangle has two legs and a hypotenuse, the length of the hypotenuse is the distance you need. The legs are 90ft long and you need to use the Pythagorean theorem. 90 squared plus 90 squared equals c squared, so 8100+8100=c^2, 16200=c^2, c=127.27922061
Answer:
Equation: 4x - 6 = -46
Solution: x=10.
Step-by-step explanation:
The difference between four times a number and six translated into a equation is: 4x - 6 = -46.
Solving for 'x'we have:
4x = -46 + 6 ⇒ 4x = -40 ⇒ x = 10.
Then, the solution is: x=10
