We know that an isosceles triangle has 2 equal sides.
We can represent the equal sides with x, and the base with y:
2x + y = 15.6
Given states that y = x - 3, so:
2x + x - 3 = 15.6
3x = 18.6
x = 6.2
y = 3.2
The sides are 6.2 m, and the base is 3.2 m.
Yes is A and the solution is that when you add negatives it restart number like 3x - - 3= 0
Answer:
The rate of change is -0.75
Step-by-step explanation:
For each unit of <em>t</em> the volume of water is decreasing by 0.75.
At <em>t</em>=13.333 the volume of water is 0. at <em>t</em>=0 the volume of water is 10
Hope this helps
X=15. This is the Altitude theorem which is Altitude/Part = Altitude/Other part. In this question you would set up the proportion 9/X = X/25 and multiply cross products to get 225=X^2. Then you undo X^2 by doing the square route of 225 and then you get 15 as the final answer.
first one is C and second is D
