Answer:

Step-by-step explanation:
Let's call B at the base of the triangle and call h at the height of the triangle. Then we know that:
The height of a triangle is 5 cm shorter than its base. This means that:
.
The area of the triangle is 25 cm²
By definition the area of a triangle is:

For this triangle we know that
and
. We substitute these values in the equation and solve for B.


Now we use the quadratic formula to solve the equation.
For an equation of the form
the quadratic formula is:

In this case note that: 
Then:



The solutions are:


For this problem we take the positive solution.

Now we substitute the value of B in the equation to find the height h


"x = 2; a = 5; b = 3" A 5 inch tall bamboo shoot doubles in height every 3 days. If the equation y=ab^x, where x is the number of doubling periods, represents the height of the bamboo shoot.
Answer:
Y = 6
Step-by-step explanation:
i know this because if it tells me that X = 1 and it shows -x+7 then i know it will be 6. Have a Great Day!
10. 24x-8. 11. 5x+6x+2x+15x=28x I hope this is right
